	There are several ways to search for files on a Linux system. The simplest is to use the '''find''' command which searches through the system directory by directory for files which match your search string. You can specify many options for the find command which do things such as restrict to searching in one particular directory and it's sub-directories, etc.		There are several ways to search for files on a Linux system.
