Issues with usage of free on CentOS 6

[willemdh]

@dimon222 @ThomDietrich

Discovered a new bug with free on CentOS 6. Results is an error message at logon. I'll need to investigate further asap..

free: invalid option -- '-'
usage: free [-b|-k|-m|-g|-h] [-l] [-o] [-t] [-s delay] [-c count] [-V]
  -b,-k,-m,-g show output in bytes, KB, MB, or GB
  -h human readable output (automatic unit scaling)
  -l show detailed low and high memory statistics
  -o use old format (no -/+buffers/cache line)
  -t display total for RAM + swap
  -s update every [delay] seconds
  -c update [count] times
  -a show available memory if exported by kernel (>80 characters per line)
  -V display version information and exit

Version:

free -V
procps version 3.2.8

[willemdh]

Found the problem.

free --version does not work on CentOS 6 which uses procps version 3.2.8

free -V does work and solves the problem for me on both CentOS 6 and 7.

@dimon222 @ThomDietrich

Can someone asap confirm free -V works on whatever OS you guys are using? Tx

Interesting, never expected such behavior. free -V perfectly works on my Ubuntu and other Debian based distributives.

Should be fixed by now I assume
