top used to support the '-M' option. It was used decide which units memory was displayed in for the machine Kib, MB, GiB etc. On RHEL 6.x this works, but it is not supported on later releases of the procps package. On RHEL 7.x it's not available as an option. Does anyone know if there is an alternative command line option for top, or why it was removed?
Why was 'top -M' removed in later versions of procps
