It does this by a variety of means available to it, depending on the platform that it is running on. * getpwent On UNIXy systems with getpwent, that can be used to determine the login shell. * dscl Under Mac OS X getpwent will typically not provide any useful information, so the dscl command is used instead. * proc file systems On UNIXy systems with a proc filesystems (such as Linux), Shell::Guess will attempt to use that to determine the running shell. * ps On UNIXy systems without a proc filesystem, Shell::Guess will use the ps command to determine the running shell. * Win32::Getppid and Win32::Process::List On Windows if these modules are installed they will be used to determine the running shell. This method can differentiate between PowerShell, command.com and cmd.exe. * ComSpec If the above method is inconclusive, the ComSpec environment variable will be consulted to differentiate between command.com or cmd.exe (PowerShell cannot be detected in this manner). * reasonable defaults If the running or login shell cannot be otherwise determined, a reasonable default for your platform will be used as a fallback. Under OpenVMS this is dcl, Windows 95/98 and MS-DOS this is command.com and Windows NT/2000/XP/Vista/7 this is cmd.exe. UNIXy platforms fallback to bourne shell. The intended use of this module is to enable a Perl developer to write a script that generates shell configurations for the calling shell so they can be imported back into the calling shell using eval and backticks or source. For example, if your script looks like this: #!/usr/bin/perl use Shell::Guess; my $shell = Shell::Guess->running_shell; if($shell->is_bourne) { print "export FOO=bar\n"; } else($shell->is_c) { print "setenv FOO bar\n"; } else { die "I don't support ", $shell->name, " shell"; } You can then import FOO into your bash or c shell like this: % eval `perl script.pl` or, you can write the output to a configuration file and source it: % perl script.pl > foo.sh % source foo.sh Shell::Config::Generate provides a portable interface for generating such shell configurations, and is designed to work with this module. CLASS METHODS These class methods return an instance of Shell::Guess, which can then be interrogated by the instance methods in the next section below. Shell::Guess->running_shell Returns an instance of Shell::Guess based on the shell which directly started the current Perl script. If the running shell cannot be determined, it will return the login shell. Shell::Guess->login_shell( [ $username ] ) Returns an instance of Shell::Guess for the given user. If no username is specified then the current user will be used. If no shell can be guessed then a reasonable fallback will be chosen based on your platform. Shell::Guess->bash_shell Returns an instance of Shell::Guess for bash. The following instance methods will return: * $shell->name = bash * $shell->is_bash = 1 * $shell->is_bourne = 1 * $shell->is_unix = 1 * $shell->default_location = /bin/bash All other instance methods will return false Shell::Guess->bourne_shell Returns an instance of Shell::Guess for the bourne shell. The following instance methods will return: * $shell->name = bourne * $shell->is_bourne = 1 * $shell->is_unix = 1 * $shell->default_location = /bin/sh All other instance methods will return false Shell::Guess->c_shell Returns an instance of Shell::Guess for c shell. The following instance methods will return: * $shell->name = c * $shell->is_c = 1 * $shell->is_unix = 1 * $shell->default_location = /bin/csh All other instance methods will return false Shell::Guess->cmd_shell Returns an instance of Shell::Guess for the Windows NT cmd shell (cmd.exe). The following instance methods will return: * $shell->name = cmd * $shell->is_cmd = 1 * $shell->is_win32 = 1 * $shell->default_location = C:\Windows\system32\cmd.exe All other instance methods will return false Shell::Guess->command_shell Returns an instance of Shell::Guess for the Windows 95 command shell (command.com). The following instance methods will return: * $shell->name = command * $shell->is_command = 1 * $shell->is_win32 = 1 * $shell->default_location = C:\Windows\system32\command.com All other instance methods will return false Shell::Guess->dcl_shell Returns an instance of Shell::Guess for the OpenVMS dcl shell. The following instance methods will return: * $shell->name = dcl * $shell->is_dcl = 1 * $shell->is_vms = 1 All other instance methods will return false Shell::Guess->fish_shell Returns an instance of Shell::Guess for the fish shell. The following instance methods will return: * $shell->name = fish * $shell->is_fish = 1 * $shell->is_unix = 1 Shell::Guess->korn_shell Returns an instance of Shell::Guess for the korn shell. The following instance methods will return: * $shell->name = korn * $shell->is_korn = 1 * $shell->is_bourne = 1 * $shell->is_unix = 1 * $shell->default_location = /bin/ksh All other instance methods will return false Shell::Guess->power_shell Returns an instance of Shell::Guess for Windows PowerShell. The following instance methods will return: * $shell->name = power * $shell->is_power = 1 * $shell->is_win32 = 1 All other instance methods will return false Shell::Guess->tc_shell Returns an instance of Shell::Guess for tcsh. The following instance methods will return: * $shell->name = tc * $shell->is_tc = 1 * $shell->is_c = 1 * $shell->is_unix = 1 * $shell->default_location = /bin/tcsh All other instance methods will return false Shell::Guess->z_shell Returns an instance of Shell::Guess for zsh. The following instance methods will return: * $shell->name = z * $shell->is_z = 1 * $shell->is_bourne = 1 * $shell->is_unix = 1 * $shell->default_location = /bin/zsh All other instance methods will return false INSTANCE METHODS The normal way to call these is by calling them on the result of either running_shell or login_shell, but they can also be called as class methods, in which case the currently running shell will be used, so Shell::Guess->is_bourne is the same as Shell::Guess->running_shell->is_bourne $shell->is_bash Returns true if the shell is bash. $shell->is_bourne Returns true if the shell is the bourne shell, or a shell which supports bourne syntax (e.g. bash or korn). $shell->is_c Returns true if the shell is csh, or a shell which supports csh syntax (e.g. tcsh). $shell->is_cmd Returns true if the shell is the Windows command.com shell. $shell->is_command Returns true if the shell is the Windows cmd.com shell. $shell->is_dcl Returns true if the shell is the OpenVMS dcl shell. $shell->is_fish Returns true if the shell is Fish shell. $shell->is_korn Returns true if the shell is the korn shell. $shell->is_power Returns true if the shell is Windows PowerShell. $shell->is_tc Returns true if the shell is tcsh. $shell->is_unix Returns true if the shell is traditionally a UNIX shell (e.g. bourne, bash, korn) $shell->is_vms Returns true if the shell is traditionally an OpenVMS shell (e.g. dcl) $shell->is_win32 Returns true if the shell is traditionally a Windows shell (command.com, cmd.exe) $shell->is_z Returns true if the shell is zsh $shell->name Returns the name of the shell. $shell->default_location The usual location for this shell, for example /bin/sh for bourne shell and /bin/csh for c shell. May not be defined for all shells. CAVEATS Shell::Guess shouldn't ever die or crash, instead it will attempt to make a guess or use a fallback about either the login or running shell even on unsupported operating systems. The fallback is the most common shell on the particular platform that you are using, so on UNIXy platforms the fallback is bourne, and on OpenVMS the fallback is dcl. These are the operating systems that have been tested in development and are most likely to guess reliably. * Linux * Cygwin * FreeBSD * Mac OS X * Windows (Strawberry Perl) * Solaris (x86) * MS-DOS (djgpp) * OpenVMS Always detected as dcl (a more nuanced view of OpenVMS is probably possible, patches welcome). UNIXy platforms without a proc filesystem will use Unix::Process if installed, which will execute ps to determine the running shell. It is pretty easy to fool the ->running_shell method by using fork, or if your Perl script is not otherwise being directly executed by the shell. Patches are welcome to make other platforms work more reliably.

This is free software, licensed under: The GNU General Public License, Version 1, February 1989 GNU GENERAL PUBLIC LICENSE Version 1, February 1989 Copyright (C) 1989 Free Software Foundation, Inc. 51 Franklin St, Fifth Floor, Boston, MA 02110-1301 USA Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed. Preamble The license agreements of most software companies try to keep users at the mercy of those companies. By contrast, our General Public License is intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. The General Public License applies to the Free Software Foundation's software and to any other program whose authors commit to using it. You can use it for your programs, too. When we speak of free software, we are referring to freedom, not price. Specifically, the General Public License is designed to make sure that you have the freedom to give away or sell copies of free software, that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs; and that you know you can do these things. To protect your rights, we need to make restrictions that forbid anyone to deny you these rights or to ask you to surrender the rights. These restrictions translate to certain responsibilities for you if you distribute copies of the software, or if you modify it. For example, if you distribute copies of a such a program, whether gratis or for a fee, you must give the recipients all the rights that you have. You must make sure that they, too, receive or can get the source code. And you must tell them their rights. We protect your rights with two steps: (1) copyright the software, and (2) offer you this license which gives you legal permission to copy, distribute and/or modify the software. Also, for each author's protection and ours, we want to make certain that everyone understands that there is no warranty for this free software. If the software is modified by someone else and passed on, we want its recipients to know that what they have is not the original, so that any problems introduced by others will not reflect on the original authors' reputations. The precise terms and conditions for copying, distribution and modification follow. GNU GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 0. This License Agreement applies to any program or other work which contains a notice placed by the copyright holder saying it may be distributed under the terms of this General Public License. The "Program", below, refers to any such program or work, and a "work based on the Program" means either the Program or any work containing the Program or a portion of it, either verbatim or with modifications. Each licensee is addressed as "you". 1. You may copy and distribute verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this General Public License and to the absence of any warranty; and give any other recipients of the Program a copy of this General Public License along with the Program. You may charge a fee for the physical act of transferring a copy. 2. You may modify your copy or copies of the Program or any portion of it, and copy and distribute such modifications under the terms of Paragraph 1 above, provided that you also do the following: a) cause the modified files to carry prominent notices stating that you changed the files and the date of any change; and b) cause the whole of any work that you distribute or publish, that in whole or in part contains the Program or any part thereof, either with or without modifications, to be licensed at no charge to all third parties under the terms of this General Public License (except that you may choose to grant warranty protection to some or all third parties, at your option). c) If the modified program normally reads commands interactively when run, you must cause it, when started running for such interactive use in the simplest and most usual way, to print or display an announcement including an appropriate copyright notice and a notice that there is no warranty (or else, saying that you provide a warranty) and that users may redistribute the program under these conditions, and telling the user how to view a copy of this General Public License. d) You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee. Mere aggregation of another independent work with the Program (or its derivative) on a volume of a storage or distribution medium does not bring the other work under the scope of these terms. 3. You may copy and distribute the Program (or a portion or derivative of it, under Paragraph 2) in object code or executable form under the terms of Paragraphs 1 and 2 above provided that you also do one of the following: a) accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Paragraphs 1 and 2 above; or, b) accompany it with a written offer, valid for at least three years, to give any third party free (except for a nominal charge for the cost of distribution) a complete machine-readable copy of the corresponding source code, to be distributed under the terms of Paragraphs 1 and 2 above; or, c) accompany it with the information you received as to where the corresponding source code may be obtained. (This alternative is allowed only for noncommercial distribution and only if you received the program in object code or executable form alone.) Source code for a work means the preferred form of the work for making modifications to it. For an executable file, complete source code means all the source code for all modules it contains; but, as a special exception, it need not include source code for modules which are standard libraries that accompany the operating system on which the executable file runs, or for standard header files or definitions files that accompany that operating system. 4. You may not copy, modify, sublicense, distribute or transfer the Program except as expressly provided under this General Public License. Any attempt otherwise to copy, modify, sublicense, distribute or transfer the Program is void, and will automatically terminate your rights to use the Program under this License. However, parties who have received copies, or rights to use copies, from you under this General Public License will not have their licenses terminated so long as such parties remain in full compliance. 5. By copying, distributing or modifying the Program (or any work based on the Program) you indicate your acceptance of this license to do so, and all its terms and conditions. 6. Each time you redistribute the Program (or any work based on the Program), the recipient automatically receives a license from the original licensor to copy, distribute or modify the Program subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. 7. The Free Software Foundation may publish revised and/or new versions of the General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Program specifies a version number of the license which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of the license, you may choose any version ever published by the Free Software Foundation. 8. If you wish to incorporate parts of the Program into other free programs whose distribution conditions are different, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally. NO WARRANTY 9. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 10. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. END OF TERMS AND CONDITIONS Appendix: How to Apply These Terms to Your New Programs If you develop a new program, and you want it to be of the greatest possible use to humanity, the best way to achieve this is to make it free software which everyone can redistribute and change under these terms. To do so, attach the following notices to the program. It is safest to attach them to the start of each source file to most effectively convey the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found. Copyright (C) 19yy This program is free software; you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation; either version 1, or (at your option) any later version. This program is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU General Public License for more details. You should have received a copy of the GNU General Public License along with this program; if not, write to the Free Software Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston MA 02110-1301 USA Also add information on how to contact you by electronic and paper mail. If the program is interactive, make it output a short notice like this when it starts in an interactive mode: Gnomovision version 69, Copyright (C) 19xx name of author Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. This is free software, and you are welcome to redistribute it under certain conditions; type `show c' for details. The hypothetical commands `show w' and `show c' should show the appropriate parts of the General Public License. Of course, the commands you use may be called something other than `show w' and `show c'; they could even be mouse-clicks or menu items--whatever suits your program. You should also get your employer (if you work as a programmer) or your school, if any, to sign a "copyright disclaimer" for the program, if necessary. Here a sample; alter the names: Yoyodyne, Inc., hereby disclaims all copyright interest in the program `Gnomovision' (a program to direct compilers to make passes at assemblers) written by James Hacker. , 1 April 1989 Ty Coon, President of Vice That's all there is to it! --- The Artistic License 1.0 --- This software is Copyright (c) 2012 by Graham Ollis.

Installing Shell-Guess is straightforward. ## Installation with cpanm If you have cpanm, you only need one line: % cpanm Shell::Guess If you are installing into a system-wide directory, you may need to pass the "-S" flag to cpanm, which uses sudo to install the module: % cpanm -S Shell::Guess ## Installing with the CPAN shell Alternatively, if your CPAN shell is set up, you should just be able to do: % cpan Shell::Guess ## Manual installation As a last resort, you can manually install it. Download the tarball, untar it, then build it: % perl Build.PL % ./Build && ./Build test Then install it: % ./Build install If you are installing into a system-wide directory, you may need to run: % sudo ./Build install ## Documentation Shell-Guess documentation is available as POD. You can run perldoc from a shell to read the documentation: % perldoc Shell::Guess dist.ini100644001750001750 132512457734574 15307 0ustar00ollisgollisg000000000000Shell-Guess-0.06name = Shell-Guess author = Graham Ollis license = Perl_5 copyright_holder = Graham Ollis copyright_year = 2012 version = 0.06 [@Author::Plicease] release_tests = 1 travis_status = 1 diag = +Unix::Process diag = +Win32::Getppid diag = +Win32::Process::List [RemovePrereqs] ; comes with Perl remove = strict remove = warnings remove = lib remove = File::Spec remove = FindBin ; optional remove = Unix::Process remove = Win32::Getppid remove = Win32::Process::List ; part of the testlib remove = FakeLogin [Author::Plicease::Upload] [Author::Plicease::Thanks] current = Graham Ollis contributor = Buddy Burden (BAREFOOT) [Meta::Dynamic::Config] META.yml100644001750001750 126012457734574 15112 0ustar00ollisgollisg000000000000Shell-Guess-0.06--- abstract: 'Make an educated guess about the shell in use' author: - 'Graham Ollis ' build_requires: Module::Build: '0.28' Test::More: '0.94' perl: '5.006' configure_requires: Module::Build: '0.28' perl: '5.006' dynamic_config: '1' generated_by: 'Dist::Zilla version 5.031, CPAN::Meta::Converter version 2.143240' license: perl meta-spec: url: http://module-build.sourceforge.net/META-spec-v1.4.html version: '1.4' name: Shell-Guess requires: perl: '5.006' resources: bugtracker: https://github.com/plicease/Shell-Guess/issues homepage: http://perl.wdlabs.com/Shell-Guess repository: git://github.com/plicease/Shell-Guess.git version: '0.06' Build.PL100644001750001750 221612457734574 15137 0ustar00ollisgollisg000000000000Shell-Guess-0.06 # This file was automatically generated by Dist::Zilla::Plugin::ModuleBuild v5.031. use strict; use warnings; use Module::Build 0.28; use lib qw{inc}; use My::ModuleBuild; my %module_build_args = ( "build_requires" => { "Module::Build" => "0.28" }, "configure_requires" => { "Module::Build" => "0.28", "perl" => "5.006" }, "dist_abstract" => "Make an educated guess about the shell in use", "dist_author" => [ "Graham Ollis " ], "dist_name" => "Shell-Guess", "dist_version" => "0.06", "license" => "perl", "module_name" => "Shell::Guess", "recommends" => {}, "recursive_test_files" => 1, "requires" => { "perl" => "5.006" }, "script_files" => [], "test_requires" => { "Test::More" => "0.94", "perl" => "5.006" } ); my %fallback_build_requires = ( "Module::Build" => "0.28", "Test::More" => "0.94", "perl" => "5.006" ); unless ( eval { Module::Build->VERSION(0.4004) } ) { delete $module_build_args{test_requires}; $module_build_args{build_requires} = \%fallback_build_requires; } my $build = My::ModuleBuild->new(%module_build_args); $build->create_build_script; MANIFEST100644001750001750 150712457734574 14776 0ustar00ollisgollisg000000000000Shell-Guess-0.06# This file was automatically generated by Dist::Zilla::Plugin::Manifest v5.031.

It does this by a variety of means available to it, depending on the platform that it is running on. =over 4 =item * getpwent On UNIXy systems with getpwent, that can be used to determine the login shell. =item * dscl Under Mac OS X getpwent will typically not provide any useful information, so the dscl command is used instead. =item * proc file systems On UNIXy systems with a proc filesystems (such as Linux), Shell::Guess will attempt to use that to determine the running shell. =item * ps On UNIXy systems without a proc filesystem, Shell::Guess will use the ps command to determine the running shell. =item * L and L On Windows if these modules are installed they will be used to determine the running shell. This method can differentiate between PowerShell, C and C. =item * ComSpec If the above method is inconclusive, the ComSpec environment variable will be consulted to differentiate between C or C (PowerShell cannot be detected in this manner). =item * reasonable defaults If the running or login shell cannot be otherwise determined, a reasonable default for your platform will be used as a fallback. Under OpenVMS this is dcl, Windows 95/98 and MS-DOS this is command.com and Windows NT/2000/XP/Vista/7 this is cmd.exe. UNIXy platforms fallback to bourne shell. =back The intended use of this module is to enable a Perl developer to write a script that generates shell configurations for the calling shell so they can be imported back into the calling shell using C and backticks or C. For example, if your script looks like this: #!/usr/bin/perl use Shell::Guess; my $shell = Shell::Guess->running_shell; if($shell->is_bourne) { print "export FOO=bar\n"; } else($shell->is_c) { print "setenv FOO bar\n"; } else { die "I don't support ", $shell->name, " shell"; } You can then import FOO into your bash or c shell like this: % eval `perl script.pl` or, you can write the output to a configuration file and source it: % perl script.pl > foo.sh % source foo.sh L provides a portable interface for generating such shell configurations, and is designed to work with this module. =head1 CLASS METHODS These class methods return an instance of Shell::Guess, which can then be interrogated by the instance methods in the next section below. =head2 Shell::Guess->running_shell Returns an instance of Shell::Guess based on the shell which directly started the current Perl script. If the running shell cannot be determined, it will return the login shell. =head2 Shell::Guess->login_shell( [ $username ] ) Returns an instance of Shell::Guess for the given user. If no username is specified then the current user will be used. If no shell can be guessed then a reasonable fallback will be chosen based on your platform. =head2 Shell::Guess-Ebash_shell Returns an instance of Shell::Guess for bash.

May not be defined for all shells. =head1 CAVEATS Shell::Guess shouldn't ever die or crash, instead it will attempt to make a guess or use a fallback about either the login or running shell even on unsupported operating systems. The fallback is the most common shell on the particular platform that you are using, so on UNIXy platforms the fallback is bourne, and on OpenVMS the fallback is dcl. These are the operating systems that have been tested in development and are most likely to guess reliably. =over 4 =item * Linux =item * Cygwin =item * FreeBSD =item * Mac OS X =item * Windows (Strawberry Perl) =item * Solaris (x86) =item * MS-DOS (djgpp) =item * OpenVMS Always detected as dcl (a more nuanced view of OpenVMS is probably possible, patches welcome). =back UNIXy platforms without a proc filesystem will use L if installed, which will execute ps to determine the running shell. It is pretty easy to fool the -Erunning_shell method by using fork, or if your Perl script is not otherwise being directly executed by the shell.
