Linux aliases are convenient shortcuts for often-used commands. They can save you time and headache when typing out long or complicated command lines, but they’re easy to set up. First, open your terminal (Command Line Interface) by finding it on your Linux computer. Once you’ve opened it up, type in the following code. This article is made by https://ask4files.com
Create an alias
To create an alias, you first need to know the name of a command. Then, you can use that name in place of the actual command. For example:
To make it easier for yourself (and your coworkers), you can create aliases for long or hard-to-remember commands. Aliases let you type a short word instead of typing out long strings every time you want to run a certain tool or command line option!
Aliases are useful because they save time and effort when typing out commands over and over again. They also help keep things organized by grouping related commands together under one name instead of having them scattered throughout different files on your computer’s hard drive. You can discover also disk cleanup compresses your os drive.
Print the list of defined aliases
- alias command
- alias -l: List all defined aliases.
- alias -p: Print the definition of an existing alias.
- alias -s: Search for an existing alias by name or description, and display its definition if found
Delete an alias
To delete an alias, run the unalias command. For example:
unalias echo
This will remove the alias for echo and any other aliases you have created. You can also use this to remove all of your current aliases at once by running:
unalias -a
Modify an existing alias
To modify an existing alias, you’ll need to use the appropriate command for your version of Linux.
- For Ubuntu and Debian:
“`sudo update-alternatives –config editor“`
This will open up a text editor where you can make any changes that you want to your alias and save them by hitting Ctrl + X > Y > Enter . The next time you run `editor`, it will be using your new settings!
For Red Hat and Fedora: “`sudo alternatives –config editor“` This will open up a text editor where you can make any changes that you want to your alias and save them by hitting Ctrl + X > Y > Enter . The next time you run `editor`, it will be using your new settings!
For CentOS: “`sudo alternatives –config editor“` This will open up a text editor where you can make any changes that you want to your alias and save them by hitting Ctrl + X > Y > Enter . The next time you run `editor`, it will be using your new settings!
Remove all aliases at once
To remove all aliases at once, you can use the unalias command. You can also use it to remove a specific alias:
- unalias
For example:
- unalias myname
Conclusion
In summary, aliases are a great way to make your Linux terminal more interactive and easier to use. They can help you avoid typing long commands or remembering complex ones. Aliases are also useful if you want an easy way to run the same command over and over again without needing to type it each time.
