p5-Shell-GetEnv

Extract shell environment after executing commands

Shell::GetEnv provides facility for obtaining changes made to environment variables as the result of running shell scripts. It does this by causing a shell to invoke a series of user provided shell commands (some of which might source scripts) and having the shell process store its environment (using a short Perl script) into a temporary file, which is parsed by the Shell::Getenv. Communications with the shell subprocess may be done via standard IPC (via a pipe), or may be done via the Perl Expect module (necessary if proper execution of the shell script requires the shell to be attached to a "real" terminal).
