  • desired path to search for files. Change it to your desired path

• -type f

  • only find files, not directories

• -exec md5sum {} \;

  • executes md5sum command for each found file, represented by {} sign here.

    • -exec COMMAND_HERE \; execute the given command on a found file.
    • md5sum {} execute md5sum command on input passed by find command using {} symbol
