No -- you can't assume that. The correct thing to do is to set $PATH
within your script, then it should stand a much improved chance of
running correctly irrespective of how it gets started. Add a line like
this near the top of the script:
export PATH=/bin:/usr/bin:/sbin:/usr/sbin:/usr/local/bin:/usr/local/sbin
That should be good enough for most purposes, but feel free to modify if
needed.
Another debugging tip: add
set -x
or
set -v -x
towards the top of the script and you'll get a trace of what the script
does e-mailed to you. (Well, e-mailed to root, but I assume yould've
been reading root's mailbox anyhow, or redirected the root e-mails to
somewhere more useful.)
> PATH is set at the top of /etc/crontab
Well, yes. However that only helps for the scripts run out of
/etc/crontab. If the OP has done the right thing and left /etc/crontab
alone, but instead set up a root crontab by running
# crontab -u root -e
then that wouldn't help at all.
Cheers,
Matthew
