Finding a Lost File
Step #1: Log in to the system as the "root" user.
Step #2: Assume the filename was "Invoice-1101". Type the following "find" command:
find / -name "Invoice-1101" -print
This command searches through the "/" (root) filesystem for the file, and prints out the location when it is found.
NOTE: If the file is not found, nothing will be printed.
If you only know part of the name, you can use that for your search. For instance, let’s say you only knew the name began with the letters "Invoice". The following command will work:
find / -name "Invoice*" -print
