Hi,
Can anoyone tell me why this command is not executed (or it is without

(yes, i've restarted crontab service)
It works from the command line? that's kind of surprising. It may work
via tab completion in the shell, but will not work with that as typed.
You'd suffer from shell expansion.

# clean up postmaster
00 30 * * * root /usr/bin/find
/var/qmail/maildirs/postmaster@xxxxxxxxx/Maildir/new -type f -print0 |
xargs -0 -n 50 rm
You very likely need to escape the @ as the shell is probably trying
to do something with it.
It's true that, using tab-completion, the @ can get escaped, but I can't
find that bash actually does anything with it in this context:
[summer@bilby ~]$ mkdir /tmp/x@j
[summer@bilby ~]$ mkdir /tmp/x\@j/
The second, I used tab-completion to expand from "/tmp/x." As you can
see, it was used as typed.
I would first, check the logs.
I generally use the user's crontab, so
crontab -e
and ensure I have a line
MAILTO=me@xxxxxxxxxxx
so I get the results mailed to me. It's good to set PATH too.
I also have had bad experiences (one day I will complain to someone's
bugzilla) with crond eating stuff. This does not work:
0 * * * * echo $(date)
The workaround is to put the command(s) into a script.
