grepit

grepit is a tool for people who constantly forget terminal commands. Instead of searching the web or digging through old notes every time you need to remember how to do something in the command line, you just type a plain-English search term and the tool finds the exact command you need. The creator pitches it as a secure way to never remember terminal commands, implying your searches stay local or private rather than being sent off to some external server.

You use it by typing a simple command followed by whatever it is you are trying to do. For example, you might search for something like "find all large files" or "restart the web server," and it returns the matching command. The README does not go into detail about exactly how the search works under the hood, so it is hard to say whether it is searching a built-in library of common commands, your own saved history, or something else entirely. The screenshots suggest it simply takes your search term and gives you back the relevant syntax.

The main audience is developers, system administrators, or really anyone who spends time in a terminal but does not want to memorize every possible command. If you have ever Googled "how to unzip a tar file" for the fifth time this month, this is the kind of tool meant to save you that step.

The project is installed by running a script directly from GitHub, which is a common setup approach for command-line tools. Beyond that, the README is quite sparse. It does not explain what makes it more secure than other options, what data it searches through, or whether you can add your own custom commands to its database. If those details matter to you, you would need to look at the source code itself.
