bash : run command on find results

Unix find command allows user to execute a command on the results by using -exec command. For example see below. {} get replaced by filename, Make sure to escape {} and ;.

find . -type f -exec ls -l {} ;

This triggers ls -l on all the files that were found. I used this with -maxdepth (how deep directory structure to examine) and -mtime (last modified time) to cleanup old files as below.

find /var/log -type f -mtime +30 -maxdepth 0 -exec rm -f {} ;
