Running on Slackware's 9.1 (~2.4.22) and running some timing tests.
This requires my use of "time" command. Nice man says -20 is highest
priority. Why then am I getting 0.001 ms if I use: nice 19 time
? AND get 0.101ms if I use: nice -20 time ?
Yes running in fg! I am only user.
Can you also explain why I cant extract time lines with grep?
I tried: time echo >/dev/null 2>&1 | grep real
and other stuff which shouldn't work and didn't.
