I’m actually not positive that is the case. The && syntax chains the commands into a dependent chain (sa-update only triggers if sa-update succeeded and sa-spamd restart only triggers if both previous commands succeeded, so it would certainly make sense that some state like setting variables is preserver. Haven’t tested this, but it’s pretty trivial. # /bin/sh # PATH=/bin:/usr/local/bin echo $PATH && echo $PATH /sbin:/bin:/usr/sbin:/usr/bin:/usr/games:/usr/local/sbin:/usr/local/bin:/root/bin /sbin:/bin:/usr/sbin:/usr/bin:/usr/games:/usr/local/sbin:/usr/local/bin:/root/bin Hm. That’s odd. Something else going on there. > The next two commands sa-compile and sa-spamd would not get PATH set > differently for them. Is that important to you? No idea. I don’t know about the internals of sa-compile.

Sa-update, portsnap, and some deleting aging emails. -- 'I really should talk to him, sir. He's had a near-death experience!' 'We all do. It's called living.'
