Unix command to find memory usage

rajeshkumar created the topic: unix command to find memory usage

Monitor processes continuously. Updates every 3 seconds by default. Displays useful information such as total memory, memory in use, % of total memory used by each process, % cpu usage of each process, and process ID (PID) of each process. Type ‘h’ for help or ‘q’ to quit. To stop (‘kill’) a process, type ‘k’ and enter the PID of the process, then enter the signal for the ‘kill’ command (see below) or press Enter to use the default signal (terminate).

Useful options:
-d Specify time between updates
-u List processes for user
-p List process with ID
-n Specify number of iterations before quitting
