Supported command line options for top
In RHEL 6.x you could run the top command with the -M option:;
[jenkins-ci@dubengvm65]~ $top -M
top - 13:33:07 up 44 days, 4:17, 1 user, load average: 0.00, 0.00, 0.00
Tasks: 150 total, 1 running, 149 sleeping, 0 stopped, 0 zombie
Cpu(s): 0.2%us, 0.1%sy, 0.0%ni, 99.8%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st
Mem: 13.599G total, 12.931G used, 684.629M free, 311.203M buffers
Swap: 3967.996M total, 4744.000k used, 3963.363M free, 3103.844M cached
but on RHEL 7.x the -M option is not supported. Any ideas why this was removed, there does not seem to be any way to specify units to top from the command line now?

Hi John,
RHEL 6 Systems are shipped with procps which contains top and RHEL 7 is shipped with procps-ng. On RHEL 7 you can Press 'E' in interactive mode to switch to a different unit representation.
reference: man 1 top ... 2c. MEMORY Usage This portion consists of two lines which may express values in kibibytes (KiB) through exbibytes (EiB) depending on the scaling factor enforced with the `E' interactive command. ...
