How to Recall the Argument of the Previous Bash Command 🤔

Ever find yourself in a situation where you need to recall the argument of a previous Bash command? Maybe you're working with multiple files or directories and can't quite remember which one you used last. Don't worry, we've got your back! In this blog post, we'll explore some easy solutions to help you recall the argument of the previous command. Let's dive in! 💪

The Common Issue: Forgetting the Argument 😩

We've all been there - typing command after command, only to forget which file or directory we used in the previous one. It's frustrating and time-consuming to manually retype the argument every time. Luckily, Bash provides a couple of nifty shortcuts to save us from this headache. 🙌

Solution 1: !$ - The Magic Shortcut ✨

One of the simplest and most effective ways to recall the last argument is by using the !$ shortcut. This clever little trick substitutes the last argument from the previous command. Here's how you can use it:

$ vi file.c
$ gcc !$

In the example above, !$ is replaced with "file.c", which allows us to compile the same file without retyping the argument. Simple, right? 😎

Solution 2: ALT+. - The Keyboard Wizardry 🧙‍♂️

If you're looking for a more interactive approach, the ALT+. keyboard shortcut can be a real lifesaver. By pressing ALT and the period key (.), you can cycle through the arguments of your previous commands. Let's see it in action:

$ vi file1.c
$ vi file2.c
$ vi file3.c

To recall the argument from the previous command, simply press ALT+. multiple times. Each press cycles through the arguments, allowing you to choose the desired one. It's like magic! 🎩✨

Solution 3: !$ vs ALT+. - Pros and Cons 🤷‍♀️

Now that we've covered both solutions, you might be wondering which one is better. Well, it depends on your preference and the situation at hand.

• The !$ shortcut is great for quickly recalling the last argument with minimal effort.

• On the other hand, the ALT+. shortcut provides more flexibility by allowing you to cycle through all the arguments from previous commands.

Choose the method that fits your workflow and gives you the most efficiency. It's all about finding your Bash command recall superpower! 💥🚀
