In this article, we will be sharing the use of aliases in Linux. Aliases are shortcuts for frequently used commands. They allow you to execute a long command with a short keyword. This saves time and makes it easier to remember commands.
Creating aliases is simple and easy. In this article, I’ll show you how to create aliases, the benefits of using them, some commonly used aliases, and best practices for using them.
So, let’s get started!
Introduction to Aliases
An alias is a custom command that you create to replace a longer command. For example, instead of typing “ls -lh” every time you want to see the list of files in a directory, you can create an alias “ll” for it. Then, every time you type “ll” in the terminal, it will execute the “ls -lh” command.
Aliases can be simple or complex, and they can include options and arguments. They can also be created for any command, including custom scripts.
How to Create Aliases in Linux
Creating an alias is simple. All you have to do is open the terminal and type the following command:
Replace “alias_name” with the name you want to give your alias and “command” with the command you want to execute.
For example, to create an alias “ll” for the “ls -lh” command, you would type:
alias ll='ls -lh'
Now, every time you type “ll” in the terminal, it will execute the “ls -lh” command.
1. Basic Aliases
Here are some basic aliases that you can create:
- “la” for “ls -a”
- “ll” for “ls -lh”
- “grep” for “grep –color=auto”
- “cp” for “cp -i” (interactive copy)
2. Advanced Aliases
Here are some advanced aliases that you can create:
- “update” for “sudo apt-get update && sudo apt-get upgrade” (update the system)
- “lsof” for “sudo lsof -i” (list open files and ports)
- “today” for “date ‘+%A, %B %d, %Y’” (display the current date)
Benefits of Using Aliases in Linux
Using aliases has several benefits:
Creating aliases for frequently used commands can save you a lot of time. Instead of typing out a long command every time, you can simply type a short keyword.
Aliases make it easier to remember commands. Instead of having to remember a long command with all its options and arguments, you only have to remember a short keyword.
3. Increased Productivity
Using aliases can increase your productivity by allowing you to work more efficiently. With aliases, you can perform tasks faster and with greater accuracy, which can help you get more done in less time.
Commonly Used Aliases in Linux
Here are some commonly used aliases:
ls Command Aliases
The “ls” command is used to list files and directories in a directory. Here are some aliases for the “ls” command:
- “la” for “ls -a” (show hidden files)
- “ll” for “ls -lh” (long listing format)
- “ld” for “ls -d */” (list only directories)
cd Command Aliases
The “cd” command is used to change directories. Here are some aliases for the “cd” command:
- “cd..” for “cd ..” (move up one directory)
- “cd~” for “cd ~” (move to the home directory)
- “cd..” for “cd ../..” (move up two directories)
Git is a popular version control system used by developers. Here are some aliases for Git commands:
- “g” for “git”
- “gs” for “git status”
- “ga” for “git add”
- “gc” for “git commit”
- “gp” for “git push”
- “gl” for “git log”
Best Practices for Using Aliases in Linux
Here are some best practices for using aliases:
1. Keep it Simple
Keep your aliases simple and easy to remember. Avoid using complicated commands or options that you might forget.
2. Avoid Overwriting Existing Commands
Avoid creating aliases that overwrite existing commands or system functions. This can cause confusion and errors.
3. Be Consistent
Be consistent in the way you create and use aliases. Use a consistent naming convention and make sure that your aliases are easy to remember.
And there you have it, guys! Aliases are a simple and effective way to save time and increase productivity in Linux. With aliases, you can execute frequently used commands with just a short keyword, making your work more efficient and effective.
