find /home -user bob

• Find every file under the directory /var/spool that was modified more than 60 days ago.

find /var/spool -mtime +60

• Find files named core in or below the directory /tmp and delete them, processing filenames in such a way that file or directory names containing single or double quotes, spaces or newlines are correctly handled. The -name test comes before the -type test in order to avoid having to call

find /tmp -name core -type f -print0 | xargs -0 /bin/rm -f

• Runs `file' on every file in or below the current directory

find . -type f -exec file '{}' \;
