Disk Fill up

[James I]

A disk fills up regularly on my system. When the disk is full a necessary process called file4 dies.The disk that fills up it /var.I need a shell script that checks the disk to see if it's full, if it is, it prunes the logfiles causing the problem in /var/log/logfile and also checks to see if the file4 process is running and if it isn't restarts it by executing /etc/init.d/file4 start

bdf | awk '{ if ($5 ~ /[8-9][0-9]/ || $5 ~ /[1][0-5][0-9]/) print }' >> $drep

rep=$(cat $drep | wc -l)


if [ $rep -ge 1 ]
mess=$(bdf /var | grep var | awk '{print $5}')
echo $mess
/usr/contrib/bin/trimlogs
else
echo no problems
fi

trimlogs


while read -r rfile
do
> $rfile
done < /var/filelist

/var/filelist is a list of log files with full path of files that you want to trim in an emergency.

I suggest you look in /var and build the list

Here are some suggestions

/var/adm/syslog/syslog.log
/var/mail/root

Take a look at sam routine tasks trim log files for more suggestions.

be careful, once this data is gone its done. No recycle bin.

Have you thought of putting /var/log in its own logical volume so it doesn't affect /var?

The solutions posted to me have not answered the question satisfactorily.I mean the script should be able to run on bash.
