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).
