Trim Log Files.

[Bill Hassell]

Here is a sample logtrim.conf configuration file.

[Geoff Wild]

I'm with Bill - just copy the file then zero out the original

cp -p syslog.log syslog.log.1

> syslog.log

Or install logrotate:

content of trimlog.sh

filesize=`cat $1 | wc -l`
trim=`expr $filesize - $2`
if [ $trim -gt 0 ]
then
sed "1,$trim d" $1 > $1TMP
mv $1TMP $1
echo $1 trimmed by $trim line
fi

usage:
for example you like to delete 100 lines of syslog.log
u need to run the the shell in following way

trimlog.sh syslog.log 100
