As developers, we spend a lot of our time in the terminal. There's a lot of helpful CLI tools, which can make your life in the command line easier, faster and generally more fun.
This post outlines my top 50 must-have CLI tools, which I've come to rely on. If there's anything I'm missing - do let me know in the comments :)
At the end of the article, I've included some scripts to help you automate the installation and updating of these tools on various systems/ distros.

Installations and Management
Most of us have a core set of CLI apps and utils that we rely upon. Setting up a new machine, and individually installing each program would get tiresome very quickly. So the task of installing and updating your terminal apps is the perfect candidate for automation. Here are some example scripts I've written, which can be easily dropped into your dotfiles or just run independently to ensure you're never missing an app.
For MacOS users, the easiest method is using Homebrew. Just create a Brewfile (with touch ~/.Brewfile), then list each of your apps, and run brew bundle. You can keep your package list backed up, by putting it in a Git repo. Here's an example one, to get you started: https://github.com/Lissy93/Brewfile
On Linux, you usually want to use the native package manager (e.g. pacman, apt). As an example, here's a script to install the above apps on Arch Linux systems
Desktop apps on Linux can be managed in a similar way, via Flatpak. Again, here's an example script :)
Conclusion
... So that's it - a list of handy CLI apps, and a method for installing and keeping them up-to-date across your systems.
Hopefully some of these will be useful to some of you :)
I'd love to hear what you're favourite CLI apps are, let me know in the comments below!
↕️ Additional Info (click to expand)
What wasn't included
- This list doesn't include the basics, like Vim, Tmux, Ranger, ZSH, Git, etc - which you're likely already using
- I've also not included anything too niche, or only specific to a small number of users
- Nothing system-specific, or that isn't cross-platform (Linux/ Unix, MacOS) is included
- And I've not included apps which relate to the terminal, but are not CLI apps (like terminal emulators)
- For most of the projects listed, there's a plethora of alternatives that achieve similar things, for brevity those also weren't included
Credit
Huge kudos to the authors, and communities behind each of these apps. Without them and their hard work, our life in the command line would be much less awesome. Where possible, I've tried to credit the authors, but if I've missed any - let me know below, and I'll push an update
Feedback
What have I missed? I'd love to hear your favourite CLI apps, especially if there's something awesome that I've missed!
I'd also like to hear your thoughts and suggestions - I'm always looking to improve :)
