20 find COMMAND Examples

find - search for files in a directory hierarchy.

find . -name file.txt
  • find command
  • . means it will search all the directory you are in and sub directories.
  • -name will look for that name exactly, if a character is different or upper or lower case, it will ignore it.
  • file.txt filename

find /home/ -iname file.txt
  • /home/ will only search this directory recursively (sub directories)
  • upper or lower case name

find /home/ -name *ile*
  • finds all files that have the word file at the beginning, middle or end
