can anybody give me a solution to truncate all logfile in /var/log/ directory?
and a question just for knowledge, is it a good idea or not?
#!/bin/bash
LOGDIR="/var/log"
for logfile in $(ls $LOGDIR/*log)
do
truncate -s 0 $logfile
done
try this:
truncate -s 0 /var/log/*log
EDIT:
if you want to do this more than once you should use logrotate to handle your logs. Usually it's installed in ubuntu. Have a look at man logrotate (or if you do not have it installed look at the online manpage or install it with sudo apt-get install logrotate)
from the manpage:
logrotate is designed to ease administration of systems that
generate
large numbers of log files. It allows automatic rotation, compression,
removal, and mailing of log files. Each log file may be handled daily,
weekly, monthly, or when it grows too large.
