Log Trim on 10.20

[Bill Pontius]

I have the following bootp and info logs that I'd like to trim. There are active DHCP files. I've added these logs to other logs using SAM and have tried various ways of trimming but none have worked. Usually it will show 0 bytes or a trimmed amount but when I do the ll or check SAM, it is back to the same growing size. I guess the worse case is to bring DHCP down, trim with SAM or echo > to logs and restore DHCP.

Hello,

Have you tried this?:

>bootp.log

That should zero out the file, even if a process is holding it open.

Could you not just save them off and zip them?

for x in `ls *log*`
do
cp $x $x.bak
/usr/contrib/bin/gzip $x.bak
cp /dev/null $x
done

...jcd...
