For Linux users, both beginners and advanced users often feel intimidated by the command line. There are so many commands to remember, which can be quite frustrating. Mastering these commands is essential for efficiently using the command line tools.
Unfortunately, there's no shortcut to this learning process. You have to memorize and practice a bit. However, there are several helpful tools available during the early stages of learning that can make things easier.
One of the most useful tools is the **history** command. When you use it, you can view all the commands you've previously executed. The Linux shell, such as Bash, stores these commands in a dedicated file. For example, in Bash, the history is usually saved in `/home//.bash_history`.
This file is stored in plain text format, so you can open it with any text editor to browse or search through your previous commands. It’s a great way to revisit past actions and learn from them.
Another helpful command is **apropos**, which helps you "discover" other commands. When you run `apropos`, it lists commands that match your search criteria along with brief descriptions. For instance, if you want to find out how to list the contents of a directory, you can type:
```
apropos "list directory"
```
This will return relevant commands. However, if you try `apropos "list directories"`, it might not work because `apropos` searches based on command descriptions, not exact keyword matches.
To make the search more flexible, you can use the `-a` flag, which means "and." This allows you to search for multiple keywords separately. Try:
```
apropos "match" -a "pattern"
```
You’ll see more results this time. While `apropos` is powerful, it has its limitations, so it's important to understand how it works.
Another tool that can help is **ZSH**, a modern shell that offers features like automatic correction and suggestions when you type a command. ZSH is highly customizable, and one of the easiest ways to use it is through **Oh-My-ZSH**, which provides a wide range of themes and plugins.
Finally, a common and practical method is using **cheat sheets**. There are many online resources with command shortcuts that you can quickly reference. You can save an image version of a cheat sheet as your desktop wallpaper for easy access.
While this isn't the best way to memorize commands long-term, it definitely saves time when you forget something. As you continue learning, you'll rely less on these tools and become more confident in your command-line skills.
Remember, it's normal to forget things or come across unfamiliar commands. That's exactly why these tools and the internet exist — to support your learning journey.
