PERL script not seeing env vars when run by cron

Boomn4x4 · 05-04-2012, 08:33 AM

I have a perl script that works fine when I run it from the command line, but now that I'm running it (as root) from cron, it isn't picking up my environment variables.

my $host = $ENV{HOST}
print "Host = $host\n";

when run from cron it results in
"Host ="

but when I run it from the shell,
"Host = myhostname"

probably HOSTNAME will work.

(Re)read 'man cron' - I vaguely remember 'cron' deals with environment in a special way.
