Question

I have a Perl script which has a variable like my $name. Can we set the contents of $name as an environment variable which we can import and use in other files?

I tried like $ENV{NAME}=name, but this is not working.

If you want to affect the environment of your process or your child processes, just use the %ENV hash:

$ENV{CVSROOT}='<cvs>';

If you want to affect the environment of your parent process, you can’t. At least not without cooperation of the parent process. The standard process is to emit a shell script and have the parent process execute that shell script:

#!/usr/bin/perl -w
print 'export CVSROOT=<cvs>';

… and call that script from the shell (script) as:

eval `myscript.pl`
