.SH NAME
dr_watch \- execute a program periodically, showing output fullscreen
.SH SYNOPSIS
dr_watch command
.SH DESCRIPTION
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\&.
.SH ENVIRONMENT
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\&.
