How to clear contents of all the files using find command

Question

Is there an easy step to clear contents of all ".log" file using find command.

Currently i am using "echo -n > filename.log" i have tried echo -n > /var/application-logs/*.log but it is not working..

is there a better way to clear contents of multiple files?

Answer 1

To clear everything find /var/application-logs -type f -name "*.log" finds, use this:

find /var/application-logs -type f -name "*.log" -exec tee {} \; </dev/null

If your version of find supports it, use + instead of \; to use a single run of tee for all of the files. Alternately, if a shell glob is sufficient:

tee /var/application-logs/*.log </dev/null

Answer 2

If you want to stop your logs from growing, use logrotate. You should not be blindly wiping logs just because they are full. There are good HOWTOs available for many different distros.

Alternatively, consider using a syslog server such as rsyslog or syslog-ng.
