1. First of all, let's open the Linux command line and enter a command. As shown in the following figure, it doesn't matter what the command is for.

2. Next we want to type a few letters to implement the above command, as shown in the following figure

3. Then we give the command an alias through alias, as shown in the following figure. Pay attention to the correct way to write it.

4. Then we enter the alias to achieve the same command effect, as shown in the following figure

5. To cancel the alias, we only need to call the unalias command, as shown in the following figure

6. Finally, if you want to see how many aliases there are on the current system, just type alias on the command line, as shown in the following figure

To sum up, aliasing commands in Linux is mainly achieved through alias, which can greatly speed up our command input speed.
