Yes, time is the program that monitors programs and shows the Maximum resident set size. Not to be confused with time Bash builtin that only shows real/user/sys times. On my Arch Linux you have to install time with pacman -S time, it's a separate package.
$ command time -v echo 1 1 Command being timed: "echo 1" User time (seconds): 0.00 System time (seconds): 0.00 Percent of CPU this job got: 0% Elapsed (wall clock) time (h:mm:ss or m:ss): 0:00.00 Average shared text size (kbytes): 0 Average unshared data size (kbytes): 0 Average stack size (kbytes): 0 Average total size (kbytes): 0 Maximum resident set size (kbytes): 1968 Average resident set size (kbytes): 0 Major (requiring I/O) page faults: 0 Minor (reclaiming a frame) page faults: 90 Voluntary context switches: 1 Involuntary context switches: 1 Swaps: 0 File system inputs: 0 File system outputs: 0 Socket messages sent: 0 Socket messages received: 0 Signals delivered: 0 Page size (bytes): 4096 Exit status: 0
Note:
$ type time time is a shell keyword $ time -V bash: -V: command not found real 0m0.002s user 0m0.000s sys 0m0.002s $ command time -V time (GNU Time) 1.9 $ /bin/time -V time (GNU Time) 1.9 $ /usr/bin/time -V time (GNU Time) 1.9
time([command])that's odd syntax, it's nevertime(), after time there's a spacetime command.
