“Command not found” is an error message that is displayed in the terminal when the shell is unable to locate an executable file or command that you have entered.

There are several reasons why this error can occur:

• You may have mistyped the command name.

• The command is not installed on your system.

• The command is installed, but it is not in a directory listed in your PATH environment variable.

• The command requires superuser or root privileges to run and you are not currently running the shell as superuser or root.
