In macOS, you can create aliases to simplify frequently used commands or to shorten long commands. An alias is a custom name for a command or group of commands. You can create and manage aliases in the Terminal app or in your shell configuration file.
To create an alias, use the
alias command followed by the alias name and the command it represents:
alias ll='ls -l'
In this example, the
ll command is an alias for
ls -l. Whenever you run
ll, it will execute the
ls -l command.

ll alias from your system.

Note that some commands may not work correctly when used with aliases. For example, if you alias
rm -i, it will prompt you for confirmation before deleting files. However, some scripts or programs may not expect this behavior and may fail unexpectedly. Use aliases with caution and only for simple, well-known commands.
