%description
|
|
Shell::Guess makes a reasonably aggressive attempt to determine the shell
|
|
being employed by the user, either the shell that executed the perl script
|
|
directly (the "running" shell), or the users' login shell (the "login"
|
|
shell). 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.
