Hi!
What's the proper way to remove the files (in subj)? Kill syslogd,
remove them and start it over again?

Thanks

You might look for a package called "cleanlog" somewhere within the
Sunsite archives, as it provides a more reasonable method in dealing
with growing system log files.

Run as a cron job, it gzips the current log file, empties it for the
next cycle and keeps two or three previous compressed versions around.

It solves the problem of disk space usage and saves this important
information. Deletion of log files is not recommended.

That'll only work with some shells (sh and ksh-derived ones).  The first
one should be portable to sh, csh, ksh, and rc-style shells.

'course, everyone should be using an sh/ksh style shell.  That doesn't
mean that they are, though...

I usually do:

        >/var/adm/messages
        >/var/adm/syslog

This retains the inode info, so there's no need to restart the logger
processes.

I just delete them then make a new file with the same name. Example
delete messages then use vi or whatever to make a new file called
messages. Never had a problem doing it this way.

Your specific log files will differ, of course.
