NAME
Shell::Source - run programs and inherit environment changes
DESCRIPTION
The Shell::Source allows arbitrary shell scripts, or other programs for
that matter, to be run and their environment to be inherited into a Perl
program.
Begin by creating a Shell::Source object, and specifying the shell it
will use.
If the shell is unknown to the module, you will also need to specify how
to run the shell in such a way that the output is a series of lines of
the form NAME=value. For example, to run a csh script:
my $csh = Shell::Source->new(shell => "csh",
file => "stuff.csh",
run => "csh -f -c 'source [[file]]; env' |");
However, for known shells this is not required. Note that [[file]] will
be replaced with the filename of the program you want to run.
Output from running the program is returned from $csh->output.
Changes made to the environment by running the program may be inherited
by calling $csh->inherit.
The environment changes are available as a hash from $csh->env, or in
Bourne shell syntax from $csh->shell.
