dr_watch(1) USER COMMANDS dr_watch(1)


dr_watch - execute a program periodically, showing output fullscreen


dr_watch command


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.


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.
