In Linux, commands help you achieve tasks like troubleshooting network issues, executing scripts, organizing system structure, and more. Moreover, some situations require you to run lengthy commands repeatedly, and typing them consumes much of your time. In this case, the alias command is the savior, creating shortcuts for long commands or a sequence of commands. It also improves productivity and reduces errors.

However, many users and even Linux experts have yet to learn how to use the alias command correctly. So, this short tutorial will quickly explain how to use the alias command in Linux without any hassles.

The alias Command with Examples

The alias command is simple, and you can use it as:

Please replace the ‘alias_name’ and ‘command’ with the name of the alias and the target command, respectively.

After that, add the aliases in the following manner:

Finally, save the file and run the ‘source ~/.bashrc’ command to apply the changes.

The alias command in Linux empowers a user to customize the command line experience and enhance productivity. By creating personalized shortcuts, you can easily streamline your workflow and navigate your system. Here, we discussed the method to create temporary and permanent aliases.
