How do I find process time?
On any given processor, the total waiting time for an ordered set of processes taking time P1.. PN to complete is the total of individual elapsed times multiplied by the number of waiting processes remaining: (N – 1)P1 + (N – 2)P2 + + PN-1.
How to check whether specified PID is currently running?
Send the signal sig to the process with the process identifier pid. Calling posix_kill with the 0 kill signal will return true if the process is running, false otherwise. I think posix_kill (posix_getpgrp (), 0) is the best way to check if PID is running, it’s only not available on Windows platforms.
How to get the PID of a process?
-f The pattern is normally only matched against the process name. When -f is set, the full command line is used. Note the [] around the first letter of the keyword. That’s a useful trick to avoid matching the awk command itself. That command should give you the PID of the processes with KEYWORD in them.
