Configuration

You can configure the behavior and output of the tldr client by setting environment variables. For example, in the .bashrc file:

export TLDR_COLOR_NAME="cyan"
export TLDR_COLOR_DESCRIPTION="white"
export TLDR_COLOR_EXAMPLE="green"
export TLDR_COLOR_COMMAND="red"
export TLDR_COLOR_PARAMETER="white"
export TLDR_LANGUAGE="es"
export TLDR_CACHE_ENABLED=1
export TLDR_CACHE_MAX_AGE=720
export TLDR_PAGES_SOURCE_LOCATION="https://raw.githubusercontent.com/tldr-pages/tldr/main/pages"
export TLDR_DOWNLOAD_CACHE_LOCATION="https://tldr-pages.github.io/assets/tldr.zip"

Cache

Cache is downloaded from TLDR_DOWNLOAD_CACHE_LOCATION (defaults to the one described in the client specification), unzipped and extracted into the local cache directory. Pages are loaded directly from TLDR_PAGES_SOURCE_LOCATION if tldr <command> is used.

Cache location

In order of precedence:

If you are experiencing issues with tldr, consider deleting the cache files before trying other measures.

Autocomplete

shtab is required for autocompletion using the --print-completion argument.

# bash
tldr --print-completion bash | sudo tee "$BASH_COMPLETION_COMPAT_DIR"/tldr
# zsh (it is recommended to check where zsh/site-functions directory is located)
## for macOS:
tldr --print-completion zsh | sudo tee /usr/local/share/zsh/site-functions/_tldr
## for Linux:
tldr --print-completion zsh | sudo tee /usr/share/zsh/site-functions/_tldr

See the shtab docs for other installation methods and supported shells.

For autocomplete in fish, while it is not supported in shtab yet, please see #183 for manually adding an autocomplete for tldr for fish.

SSL Inspection

For networks that sit behind a proxy, it may be necessary to disable SSL verification for the client to function. Setting the following:

will disable SSL certificate inspection. This should be avoided unless absolutely necessary.

Colors

Values of the TLDR_COLOR_x variables may consist of three parts:

You may specify as many additional effects as you want, while only one of font and background color.

Any of the values above may be omitted. For example, you can do similar things as the following:

Language

The language that tldr will use is dependent on several factors. If you specify a language via the --language flag, tldr will attempt to use that language and only that language. Otherwise, it will try to use the language specified by TLDR_LANGUAGE. If it is not set, or the page does not exist in that language, then tldr will use the language set using LANGUAGE and LANG (ignoring the values C and POSIX).

If neither is set, then tldr will always attempt to get the en page. Finally, if LANG is set, it uses LANGUAGE, if set, first, as the priority list to try languages in, followed by LANG if not included in LANGUAGE and en as a fallback (assuming it does not already appear somewhere in LANGUAGE or LANG).

All language values should be set to a value that follows RFC 1766, with the special exceptions of C and POSIX which are ignored.

Remote source

If you wish to use your own instance of the tldr pages instead of the default repository, you can either use the --source flag when using tldr or by specifying the following environment variables:
