I am a newbie to linux and I am trying to watch a command and try to log it into a file. I tried
watch -t -n 10 "(date '+TIME:%H:%M:%S'
; ps aux | grep "pattern" | wc -l)" >>
logfile
and am expecting a result like
TIME: 10:32:30 12
TIME: 10:32:40 18
TIME: 10:32:50 2
to be stored in logfile. However, when the logfile has unprintable characters in in. How do I get this kind of output from the command li

In order to do what you are looking for, a simple script (as @Ignacio pointed out) should do the trick:
I use
tee
instead of>>
so that you can see the output on your terminal as well as capture it in your log.
