Let me ask you a question. Have you ever used the `man` command? If you haven’t, try now. Open your terminal window and run this:

```
man man
```

What do you see? Are feeling overwhelmed yet? Okay, long story in short — the `man` command is an interface for reference manuals of various commands. If you want to know what does a specific command do, it is your friend. It will show you every tiny detail of that command. But while that huge amount of information is useful in learning a command in-depth, it can also be quite painful if you just want to glimpse through some basic usages pronto.

That is the problem **`tldr`** aims to solve. Let’s take a look!

## TLDR

In general, TLDR is an internet slang for “[Too Long Didn’t Read](https://en.wikipedia.org/wiki/TL;DR?ref=itsfoss.com)” and you might now understand the logic behind the name of this project.

TLDR is a community-driven project that simplifies the *man* pages. And every entry comes with useful practical examples. Let’s look at an example and compare it to `man` output.

The `man` page for the `ls` command is the following:

![man ls - Output](https://itsfoss.com/content/images/wordpress/2017/06/man-ls.jpg)

man ls – Output

And it goes on for about 234 lines! Now, let’s see the `tldr` page for `ls` :

![tldr ls - Output](https://itsfoss.com/content/images/wordpress/2017/06/tldr-ls.jpg)

tldr ls – Output

And that’s just it, covering the basic usages in less than 25 lines!

If you are new to the terminal, TLDR is a great tool that will help you learn the basic usages of various commands. Whenever you wonder what a particular command can do or might do, just type:

```
tldr <command>
```

and hit Enter. It’s just as simple as that. Also, if you just feel like learning a new command, you can try:

```
tldr --random
```

It will show tldr-page for a random command.

TLDR is not only limited to the terminal. There is a live Web Client available if you want to use it without installing anything on your system. Just open it in your favorite browser.

[TLDR Web Client](https://tldr.ostera.io/?ref=itsfoss.com)

And you can search for various commands’ man pages from there.

### Installing TLDR on Ubuntu using Node.js

Being a beloved project by the community, TLDR has many clients. You can find a list of them in the [GitHub project page](https://github.com/tldr-pages/tldr?ref=itsfoss.com#clients). However, the official client is a Node.js application. For running it, you must have Node.js installed on your system. [Installing Node.js on Ubuntu](https://itsfoss.com/install-nodejs-ubuntu/) is a rather easy task. Let’s do it first:

```
sudo apt install nodejs npm
```

That’s it. Now for installing TLDR, use the following command:

```
sudo npm install -g tldr
```

Now, TLDR is ready for use. However, the first thing you might want to do is updating the TLDR cache:

```
tldr --update
```

TLDR is an active project. New manuals are being added frequently. So if you couldn’t find the entry for any command, you can try updating the cache.

### Installing TLDR on Ubuntu using Bash

As I said, there are several clients for this tool. If you don’t want to use the Node.js version, you can go for the unofficial [Bash client](https://github.com/pepa65/tldr-bash-client?ref=itsfoss.com).

To install it, just use the commands below:

```
loc=/usr/local/bin/tldr  
sudo wget -qO $loc https://4e4.win/tldr
sudo chmod +x $loc
```

And then you can start it with the command tldr.

### Troubleshooting tip:

If you are getting “/usr/bin/env: node: No such file or directory” error while running npm command to install some node module, you can easily fix it.

What happens here is that the program looks for binary with path /usr/bin/env whereas the correct path in the system might be /usr/bin/nodejs. Making a soft link should fix it:

`ln -s /usr/bin/nodejs /usr/bin/node`
