If I have a command that each time gives me a output, (a status, for example). How I can do it to refresh this output every 2 seconds, for example? I remember that there is one command which can do it.
Example:
cat /proc/mdstat
[======>..............] resync = 30.8% (150544832/488383936) finish=65.8min speed=85472K/sec
othercommand cat /proc/mdstat
