Assuming you have a find command of
find . -type f -name '*.log'
Then it’s as simple as:
for item in $(find . -type f -name '*.log' ) ;do cat /dev/null > $item ;done
Handy for truncating log files…

Thanks for the tip, saved my time.
Great tip, thanks.
Good one 🙂
Hard to find the answer on search engines. They all think I’m looking for zero byte files. Great when I found this! I trimmed it a bit though by removing the superfluous “cat /dev/null” :
for CleanUp in $(find / -type f -name known_hosts ) ; do > $CleanUp ; done
Thanks! Exactly what I was looking for.
Do not use for i in `find …`; do… to handle files found with find because you’ll get in trouble with files with spaces in their filenames.
Use something like this:
find /var/log -type f -exec truncate -s 0 {} \;
To cleanup the whole /var/log directory I use these few lines:
CMD_FIND=”/usr/bin/find”
$CMD_FIND /var/log -type f -name ‘*.gz’ -exec rm -f ‘{}’ \;
$CMD_FIND /var/log -type f -name ‘*.[0-9]*’ -exec rm -f ‘{}’ \;
$CMD_FIND /var/log -type f -exec truncate -s 0 {} \;
