I noticed that procps-ng has -H--human flag

procps/src on  master via C v15.2.0-gcc ❯ ./hugetop -h
Usage:
hugetop [options]
Options:
-d, --delay <secs> delay updates
-n, --numa display per NUMA nodes Huge pages information
-o, --once only display once, then exit
-H, --human display human-readable output
-h, --help display this help and exit
-V, --version output version information and exit

And in procps-ng, this parameter affects how the entries are output:

procps/src on  master [?] via C v15.2.0-gcc ❯ sudo ./hugetop -H --o hugetop - Fri Jun 5 17:34:20 2026
