# tldr



A fully-functional POSIX shell client for [tldr-pages](https://github.com/tldr-pages/tldr).

This version aims to be the easiest, smallest, and most universal client to set up

on a new account, without sacrificing any features. It uses only `/bin/sh` features

and `curl`, and tested on Linux, OSX, FreeBSD, with `bash`, `sh`, `dash`, `ksh`,

`zsh`, `csh`.

## Installation

```bash

mkdir -p ~/bin

curl -o ~/bin/tldr https://raw.githubusercontent.com/raylee/tldr/master/tldr

chmod +x ~/bin/tldr

```



Then try using the command! If you get an error such as _-bash: tldr: command not found_,

you may need to add `~/bin` to your `$PATH`. On OSX edit `~/.bash_profile`

(`~/.bashrc` on Linux), and add the following line to the bottom of the file:

```bash

export PATH=$PATH:~/bin

```



If you'd like to enable shell completion (eg. `tldr w` to get a

list of all commands which start with w) then add the following to the same

startup script:



```bash

complete -W "$(tldr 2>/dev/null --list)" tldr

```



Or for `~/.zshrc`, add:

```bash

[ -f ~/bin/tldr ] && compctl -k "($( tldr 2>/dev/null --list))" tldr

```



## Prerequisites



`curl` and `unzip` need to be available somewhere in your `$PATH`. The script is otherwise self-contained.



## Usage



```

tldr [options] 



[options]

  -l, --list             show all available pages

  -L, --language [code]  override language detection, set preferred language

  -p, --platform [name]  show page from specific platform

  -u, --update           update cached copies of tldr page files

  -h, --help             this help overview

  -v, --version          show version information

  -n, --no-cache         display pages directly from GitHub (watch ratelimits)



  Show the tldr page for command.



The client caches a copy of the tldr pages under $(cache_dir)

By default, cached copies will be refreshed after $(cache_days) days.



Examples:

	Show an overivew of unzip:

		tldr unzip

	Show commands for all platforms:

		tldr -l -p all

	If you have fzf installed, try:

		tldr -l -p all | fzf --preview 'tldr {}' 

	Show the Russian page for tar:

		tldr -L ru tar

	List pages in the Android section:

		tldr -p android -l

```



## Customization

You can change the styling of the output from `tldr` by defining some environment variables. For

example, try adding the following lines to your `~/.bash_profile` file (OSX) or `~/.bashrc` file

(Linux).



```bash

export TLDR_HEADER='magenta bold underline'

export TLDR_QUOTE='italic'

export TLDR_DESCRIPTION='green'

export TLDR_CODE='red'

export TLDR_PARAM='blue'

```



Possible settings are: `black`, `red`, `green`, `yellow`, `blue`, `magenta`, `cyan`,

`white`, `onblue`, `ongrey`, `reset`, `bold`, `underline`, `italic`, `eitalic`, `default`

_(some variables may not work in some shells)_.



NB: You will need to log into a new session to see the effect. Just run the commands in the

terminal directly to see the change immediately and temporarily.



## Contributing



This is the result of a Sunday afternoon project. It's been lightly tested under Mac OS X 10.9

and Ubuntu Linux 15.10. I've tried to make the project as portable as possible, but if there's

something I missed I'd love your help.
