'find' command with examples

The find command is used to locate files on a Unix or Linux system. 'find' will search any set of directories you specify for files that match the supplied search criteria. You can search for files by name, owner, group, type, permissions, date, and other criteria. The search is recursive in that it will search all sub-directories too.
