in reply to Changing a unix users environment

if you want to use a Perl script to change your current shell environment you basically have to make a shell script that evals the output of the Perl script, then source the shell script (or run the eval manually).

Something like: 

#!perl
print "setenv FOO bar\n";

[download]
shell script would have... 
eval `perl_script.pl`

[download]
or whatever... is a pain since you still need to output shell commands, and may or may not need to semi-colon separate them...
