This video describe about two commands.
which command is used to find the real path of the command where the command executable resides.
whatis command is a single line manual of each command. Altough most of the shell commands have the whatis manual, some of them are not available.
you must check check with all of your command and dig into the whatis command alongwith which command.
For the Linux command line Interface video I have used here the Arch Based Manjaro Distro and Guake Terminal with BASH SHELL
12 | "which" - path of the command | "whatis"- one line manual of command | Linux CLI
