The Linux system provides a useful tool called alias, which allows us to set an alias for commands that need to be used frequently but are too lengthy, which can be achieved by typing a short alias later.

1. Set alias = 'original command-options / parameters' 1

For example:

Alias ll='ls-lt'1

In this way, the alias of the ls-lt command is ll, and when the terminal enters ll, it is equivalent to entering the ls-lt command

For example:

Unalias ll14. Set the alias to be available for each login

The alias command only works on the current login operation. If you want to be able to use aliases for these commands every time you log in, you can store the corresponding alias commands in the ~ / .bashrc file.

Open the ~ / .bashrc file, enter the alias command you want to set, save, and then run

Source / .bashrc1

If this does not work, there is no ~ / .bashrc file or the ~ / .bashrc file is not executed in the file.

You can add the command source ~ / .bashrc to ~ / .bashrc and save it.

In this way, you can use the set command alias after each login.
