Re: error messages not getting logged when running script from cron
I am seeing a bizarre behavior. The command works fine when called directly from prompt, but when invoked via cron, there is no output nor mail.
This works fine:
script 2>&1 | tee /tmp/ff ; mailx -s "email" -myemail@company.com < /tmp/ff
Now, I place the identical line in crontab file and the output file /tmp/ff does not get generated.
Inside script, i am running a pg_restore which dumps output to stdout. The usage of tee is the only way to cause it to go into a file.
Any idea here? Thanks

Uh, read it again: you're redirecting stdout to /dev/null and then
redirecting stderr to go where stdout goes. So all output is
going to the bit bucket, not the pipe.
