Create Alias Into Hosting Bash – If you’re tired of typing long commands over and over again, it’s time you try using bash aliases. Bash aliases essentially let you create a short, memorable command and use it in place of a longer command.
In this article, we’ll go over how to create a Bash alias for those long commands you’re reluctant to type.

Command followed by the name or short command you want to use, and put it directly to the command you want to run, encapsulated in a string.

For example, to create an alias to list a directory in verbose format, you would normally have to type
If you declare a bash alias in sudoterminal, it stays in memory as long as the terminal session is active. Once you close the terminal, the alias will be removed. To make an alias permanent, you must declare it in the
Step 3: When done, save and exit the file. Now update the file with the following command.
We have already covered bash functions in a previous article. The great thing is that you can also create bash aliases using functions and passing arguments. This adds a whole new level of versatility to your aliases.

The basic syntax for this is the same as for bash functions, except that the name of the function becomes your alias.
In the example below, we created a bash alias function that creates a directory with the name passed as an argument and then enters the directory.

How To Create Custom Bash Commands?
Aliases allow you to give short names to commands that you run all the time. You use the Set-Alias cmdlet to give your alias a name and the command to run—that is, if you can’t type
If you want to alias more complex commands, you can first create a function and alias the function. So if your morning routine starts with opening Chrome, Firefox, VS Code, and Slack, you can wrap that in a function and give it an alias
Use Start means the feature doesn’t wait for the apps to start before moving on to the next one. You can specify explicit paths if required.
But aliases live only for the duration of the session. To make them persistent, you need to save them in your PowerShell profile – so they will be applied every time you start a session.

The alias command in Linux allows you to create custom shortcuts for commands. For example, if you often use the ls command to list files in a directory, you can create an alias called ll that automatically runs the ls command with the -l (for long listing) flag.
Linux comes with ready-made alias commands by default. You probably use these commands regularly without even knowing it.

In the terminal, type alias and press enter. This will print all alias commands on your system.
To create an alias command for your current session, type alias name = command at the command prompt, like so:
This creates a temporary alias command that lists the contents of the current directory with the -l (for long listing) flag.
To use the new temporary alias on Linux, type the command name in the terminal.
Linux And Unix Host Command Examples
To create a persistent alias on Linux, first open a new terminal. Opening a new terminal window will open your user’s home directory.
The new alias command will change our directory to the user’s document directory when the alias ‘docs’ is run.
Alias commands in Linux are a great way to speed up your workflow when performing repetitive tasks. In Linux, create an alias for long commands to reduce the risk of errors. This quick guide addresses a common question whose terminology can confuse newcomers: How do I create a bash shell alias? For those who thought the phrase was Greek, let’s start here: Bash is the “burn again shell”. (It’s no relation to the movie character Matt Damon, for better or worse. ;P) In the “command line interface” world, bash was the standard for decades and is still the most common “terminal”. Use. In the “terminal” world, bash aliases solve a common problem: the desire to get things done faster and more efficiently. That’s why we guide you quickly and efficiently through the creation of BASH aliases.
One of the most obvious things about the terminal – especially for those of us living in the touch and GUI age – is how much you need to type. Typing `ssh firstname.lastname@example.org` will never feel as fast as, for example, pressing a touch button. As a result, some people just never like the terminal. Although hardly a solution to all your ailments, BASH (and most other Unix terminals) offer a solution to the problem of typing long commands. They are called “aliases”. They are basically shortcuts to commonly typed sequences that can be as short as one letter. In the case of this video, we did just that.
Bash Aliases To Increase Your Productivity
In this video I alias (the already short :P) command ‘clear’ to be executed with the letter ‘c’. This can serve as a template for you to create many other relevant aliases that are more specific to your work. Here is the video:
. If you run that in your terminal, you’ll have a working alias, which means typing “C” will clear your terminal window. The problem is, as soon as you exit the terminal session, that alias disappears. Because of this, you typically use a more complex feature of BASH when creating aliases. You use these
File to save the alias commands and run them again every time you restart your terminal. BASH looks for these two files and runs them before opening, so your aliases are always there.
File, or your new session may not load it. The second issue is beyond the scope of this quick guide, the first one just requires you to repeat the steps we went through. Happy hacking!
