A And L Ls Bash

Shell Programming

Today, I want to talk about the handy a and l commands in the bash shell. Whether you’re a newbie or a seasoned developer, these commands can make your life easier when navigating through directories and files. Let’s delve into the intricacies of these commands and explore how they can streamline your workflow.

The a Command

The a command is a custom alias that I personally set up in my bash environment. It’s a shortcut for the alias command, allowing me to quickly create and manage aliases for frequently used commands. For example, if I want to create an alias for the ls -l command to list files in long format, I can simply type a ll='ls -l' in the terminal. This creates an alias “ll” for ls -l, and I can now use ll to achieve the same result. It’s a real time-saver!

The l Command

Now, let’s talk about the l command. This is another custom alias that I find extremely useful. I set it up to be an alias for ls with additional options like -lh to display file sizes in a human-readable format. This means that whenever I type l in the terminal, it’s equivalent to running ls -lh. It’s such a simple alias, but it has made my directory listing tasks much more efficient.

Personal Touches and Commentary

I’ve always believed in customizing my development environment to suit my workflow, and creating these aliases has been a part of that. It may seem like a small change, but the time and effort saved by using a and l commands have added up over time. Plus, it just feels great to have these personalized shortcuts that I can rely on every day.


In conclusion, the a and l commands have proven to be valuable additions to my bash arsenal. By creating these custom aliases, I’ve been able to simplify common tasks and navigate through directories with ease. I encourage you to explore the customization options in your shell environment and find ways to tailor it to your specific needs. You might be surprised by how much of a difference it can make in your daily coding endeavors.
