Are you new to Linux or looking to expand your command-line skills? You’re in the right place! While you might be familiar with basic commands like ls and cd, there’s a world of lesser-known tricks that can make your life easier. In this blog post, we’ll explore five unique Linux command tips that you probably haven’t heard of before. These tips are not only useful but also beginner-friendly. Let’s dive in!
1. Use tree to Visualize Directory Structures
If you’ve ever struggled to understand the structure of a complex directory, the tree the command is your new best friend.
tree /path/to/directoryThis command displays the directory structure in a tree-like format, making it easy to visualize how files and folders are organized. It’s beneficial when you’re working on projects with many nested directories.
Pro tip: Use tree -L 2 to limit the display to two levels deep, perfect for getting a quick overview without overwhelming details.
2. Quickly Create Multiple Files with touch
Need to create several files at once? The touch command can do more than just update timestamps!
touch file1.txt file2.txt file3.txtThis single command creates three empty files. You can create as many files as you need in one go, saving you time and effort.
3. Use history to Recall and Reuse Commands
Can’t remember that long command you used yesterday? The history command is here to help.
history | grep "keyword"This command displays your command history, filtered by a keyword. It’s incredibly useful when you need to recall a complex command you’ve used before.
Bonus tip: Use !number to rerun a command from your history. For example, if the command you want is number 42 in your history, just type !42 to run it again.
4. Monitor System Resources with htop
