Search for big files and directories

Finding all large directories – For example find all directories taking 50k (kilobytes) blocks of space. This is useful to find out which directories on system taking lot of space.

find / -type d -size +50k

Finding all large files over 20000 KB:

find / -type f -size +20000k

Find big files in /usr and list them with ls:

find /usr -type f -size +20000k -exec ls -alh {} \;

Find big files everywhere but in /var and list them:

find / -type f -size +20000k -exec ls -alh {} \; | grep -v /var*

Restrict the search on a single mount point:

find / -mount -size +800k -type f -printf "%k %p %\n"
