crontab log removal

hello,

i know that this is not the correct forum, but i am not sure where to put a crontab question, so i came
here.

my question is probably very easy for those of you that use crontabs:

i want to remove my logs once a day, i found this in a tutorial:

45 23 * * * /usr/local/bin/vnukelog

but i am not sure if this is a standard way of doing this, or if i have to edit it to fit into my server,
and if so, what should i be putting where?

thanks for any help..

The syntax of your crontab is correct (Running a daily job at 23:45PM). In fact, your question really has nothing to do with crontab.

Why you wanted to remove it? You should rotate it instead. man 8 newsyslog. If you are worrying about those already rotated logs like messages.0.gz, you can run a cron to recombine and remove it. Like writing a script that will zcat the content of messages0.gz and place it to another file like /var/private/messages/messages_log, then delete the messages.0.gz on exit. Yes, your /var/private/messags/messages_log may accumulate to be very large file. What I would do is to run another cron to post-process this message_log and remove unwanted entries and preformat it and insert into a database.

Anyhow, read up the manpage of newsyslog, maybe that's what you really wanted to do.
