Re: Set shell environment variables from within a perl script

environment variables can only be set for the current process, and are passed on to the child processes at fork()/exec().

IOW, your example doesn't work because it executes the export command in a child process (the shell) which then immediately exits.

You probably want something like:

$ENV{CVSROOT} = "something";
system("cvs whatever") and die;

`system("cvs whatever") and die;` I might be wrong but wouldn't `exec("cvs whatever");` have the same effect? Cheers, JohnGG	[reply] [d/l] [select]

Only if the system line is the last one in the program (exec never returns, unless it completely fails to start the new program). "What should it profit a man, if he should win a flame war, yet lose his cool?"	[reply]
