|
|
<pre><code>Usage:
|
|
|

|
|
-u --update Update the local cache
|
|
-c --clear-cache Clear the local cache
|
|
-p --pager Use a pager to page output

|
|
</code></pre>
|
|
<h1><a class="header" href="#configuration" id="configuration">Configuration</a></h1>
|
|
<p>Tealdeer can be customized with a config file called <code>config.toml</code>. Creating
|
|
the config file can be done manually or with the help of <code>tldr</code>:</p>
|
|
<pre><code>$ tldr --seed-config
|
|
</code></pre>
|
|
<p>The configuration file path follows OS conventions. It can be queried with the
|
|
following command:</p>
|
|
<pre><code>$ tldr --config-path
|
|
</code></pre>
|
|
<p>On Linux, this will usually be <code>~/.config/tealdeer/config.toml</code>.</p>
|
|
<h2><a class="header" href="#override-config-directory" id="override-config-directory">Override Config Directory</a></h2>
|
|
<p>The directory where the configuration file resides may be overwritten by the
|
|
environment variable <code>TEALDEER_CONFIG_DIR</code>. Remember to use an absolute path.
|
|
Variable expansion will not be performed on the path.</p>
