	passing environment variables through to screen by Bugzilla from markd@kermodei.com :: Rate this Message: \| View Threaded \| Show Only this Message Is there a way to cause screen to pass through environment variables when invoked? My particular problem is TMPDIR, which varies on different systems we have.

	Re: passing environment variables through to screen by Kevin Van Workum-4 :: Rate this Message: \| View Threaded \| Show Only this Message As far as I know, screen behaves like any other process and inherits its environment. So invoking screen as follows should work, if not, then you have some other problems.

	Re: passing environment variables through to screen by Bugzilla from markd@kermodei.com :: Rate this Message: \| View Threaded \| Show Only this Message Thanks for the response. In case this hits anyone else, the problem is this is a Linux security measure due to screen being setgid. This seems Linux-specifc in the system and specific to TMPDIR and certain other environments variables. See below. It's mentioned here: https://bugzilla.redhat.com/show_bug.cgi?id=129682#c1 Although this is not documented in man ld.so(8) as suggest in one of the postings. The best work around I can see is to have TMPDIR set in /etc/screenrc. Mark FreeBSD 8.2, OS/X 10.7.4: TMPDIR=/var/barney FRED=fred screen echo $TMPDIR /var/barney echo $FRED fred CentOS 5.2, Ubuntu 12.0 TMPDIR=/var/barney FRED=fred screen echo $TMPDIR bash: TMPDIR: unbound variable echo $FRED fred Kevin Van Workum <vanw+screen@...> writes: > As far as I know, screen behaves like any other process and inherits > its environment.
