Re: setenv in perl

I'm not sure if I understand you correctly, but if you are trying to set the environment of the parent process calling your Perl script, then that's not possible.

The environment is always copied from parent to child process and not shared.

A changed environment in your Perl script is only visible inside this script and children processes of that script.

If your problem is in the other direction, try export with variables meant to be available to a child process

lanx@ubuntu:~$ export TEST=TRUE
lanx@ubuntu:~$ perl -E 'say $ENV{TEST}'
TRUE

Can you `qx/export .../`?	[reply]

you can but it doesn't make sense, since %ENV is by definition automatically exported. lanx@ubuntu:~$ perl -E '$ENV{TEST}=TRUE; say `echo \$TEST` ' TRUE [download] Again, you can only effect the child process. ( update: please note you have three different processes in this example: `~$` Bash > Perl `-E '...'` > `Bash` ) If you want to effect the parent process, you need to return text information which is either eval'ed or source'd (when put into a file). lanx@ubuntu:~$ eval `perl -E 'say q{export TEST=TRUE}'` lanx@ubuntu:~$ echo $TEST TRUE [download] In other words the parent process always keeps full control of the environment.
