The possible search criteria include a [[pattern matching|pattern(contracted; show full) find /foo -type d -empty -delete

Delete files and directories (if empty) named <code>bad</code> 
 find /foo -name bad -delete

 find /foo -delete)

 find /tmp -exec grep "search string" '{}' /dev/null \; -print

The <tt>[[/dev/null]]</tt> argument is used to show the name of the file before the text that is found. Without it, only the text found is printed.  An equivalent mechanism is to use the "-H" or "--with-filename" option to grep:
