<h2>NAME</h2>
<p style="margin-bottom:0" class="asd_par">
dr_watch &mdash; execute a program periodically, showing output fullscreen</p>

<a name="synopsis"></a>
<h2>SYNOPSIS</h2>
dr_watch command

<a name="description"></a>
<h2>DESCRIPTION</h2>
dr_watch behaves like watch(1): it runs command repeatedly, displaying its
output. By defaults, it executes "sleep 2" before it refreshes the program's
output: it behaves as watch. However, unlike watch, it supports refreshing the
screen when some external command, passed in the DR_SLEEP_CMD environment
variable, exits.
If DR_NICE_WATCH is set to "false", it tests wether watch(1) is available on
the system and runs it if found.

<a name="environment"></a>
<h2>ENVIRONMENT</h2>
dr_watch honors integer DR_SLEEP: number of seconds to wait between execution;
DR_SLEEP_CMD: e.g. 'sleep 5' or 'mpc idle'; and DR_NICE_WATCH: set this to
"false" if you prefer traditional watch over our reimplementation.
