[gpfsug-discuss] -Y option for many commands, precious few officially!

[Marc A Kaplan]

Just looking/scanning the latest (4.2.2) Spectrum Scale Command (and 
Programming) Reference I only found a few commands that officially are 
documented as supporting a -Y option:  mmnfs, mmsmb, mmuserauth.

But as many of you have discovered, -Y is accepted and yields 
"interesting" output for many of the mmXXXX commands. 
Moreover the output *seems to* have easily discernible patterns that can 
be parsed by simple programs.

I believe there is no guarantee that the exact command output formats will 
not change from release to release, so, as a practical matter, if you're 
going to parse command output, you're probably better off parsing the -Y 
output, even if that is not officially supported.
