    Hi,
    There was a post on this forum which seems to have disappeared :( . It showed how to get a crontab listing for all users by parsing the passwd file and then display the crons for each user found.

    Can anybody remember how this was done?

    This is probably it, if you're talking linux anyway

    cut -d: -f1 /etc/passwd | grep -vE "#" | xargs -i{} crontab -u {} -l

    I was gonna suggest:

    crontab -l | tee `awk -F":" '{ print $1}' /etc/passwd

    I tested this on Solaris 10 and it works. It wont work on SuSE 9.2 as it seems tee is only passing back the first user, which is root.

    Thanks guys, I have something to go on from here. I need this for Solaris 8 & 9 and for Tru64 systems. Thanks again.

    the command i posted should work for you so, the only problem is there is no way of identifying which crontab belongs to which user then they are all together

    One point to note is that /etc/passwd isn't necessarily an authoritative list of all user accounts on a system. It is only one potential source albeit the most common. It's a far better idea to use 'getent passwd' in any scripts that do this as it will include all potential NSS passwd sources (LDAP, NIS, PAM-MySQL, ...) and as such avoid problems should extra sources be added.
