In Operation
Let’s have a look at tldr in operation. Type tldr followed by the command or program you want to learn more about.
When the program is run for the first time, the software updates the cache and creates an index of all the community pages.
In the image below, we show the information for cp, a command used to copy files or group of files or directories.
As you can see, we’re presented with succinct and pertinent information. Rather than listing every option in alphabetical order as man pages do, the community that maintains the tldr database covers the key options and sorts them with helpful explanatory text with examples.
Sometimes you’ve been browsing the tldr community pages. You can’t remember which specific page you were reviewing but can remember a specific word or phrase. There’s a --search option which searches through the tldr database and displays matches for the search term. In the example below, we’re searching for any page that contains the word nested.
If you like to find out about new commands and programs, there’s a couple of options that show a random command or a random example.
Maintenance
The software stores a cache of the community pages on your systems. There’s a few commands to maintain the cache, and to list them.
$ tldr -c – clears the cache.
$ tldr -u – updates the local cache.
$ tldr -l – list all commands in the cache.

I love tldr. Somewhat surprised it wasn’t included earlier. I found it indispensable when I was starting out. The manual pages are find when you know what you are doing but are a pretty lame introduction.
I always recommend my students consult tldr and cheat.sh before exploring other documentation. Personally I prefer tealdeer, it’s written in Rust, and probably the quickest implementation.
I love the Rust client too.
I think you are referring to tealdeer. Like tldr, neither needs a network connection to use it (except to update the cache). I often have an unreliable net connection. the tools get round this issue, I can still keep learning
