Sometimes when using find, you end up with "Permission denied" errors that add noise to your output. There are a couple solutions for this. Use the '''prune''' option to skip entire trees that you should avoid (e.g. /proc). Use shell redirection to ignore remaining error messages (e.g. 2>/dev/null).
The following example searches all of my hard drive starting at / but skips over the backups directory I have in my external disk drive and also skips over the "process" directory. Any errors like files in /var that I do not have permission to see are discarded by redirecting STDERR to the bitbucket.
<source lang="bash">
find / -path /media/disk/backups -prune -o -path /proc -prune -o -type d -name soffice.cfg 2>/dev/null
