How do I check the maximum amount a RAM a process uses similar to how time works?

$ time mvn package
real    0m35.796s
user    0m32.925s
sys     0m1.559s

$ maxmem mvn package
688 MB

Try using GNU time instead of the built-in.

On CentOS, you would install it with yum install time then run it with /usr/bin/time <command>

Note that you need to specify the full path; otherwise the shell will want to use the built-in time

  • Oh wow I didn't know that was a built-in and /usr/bin/time already gives memory usage. – Chloe Feb 4 at 22:29
