[gpfsug-discuss] Did you know about "-Y" ?? I sure didn't... game changer

[Bryan Banister]

What's nice is that the "-Y" output provides a HEADER so that you can still programmatically determine fields of interest... this is the best!

I recommend adding "-Y" option documentation to all supporting GPFS commands for others to be informed.

If you build a monitoring pipeline using -Y output, make sure you test between revisions before upgrading. The columns do have a tendency to change from time to time.

Apparently, though not documented in man pages or any of the GPFS docs that I've read (at least that I recall), there is a "-Y" option to many/most GPFS commands that provides output in machine readable fashion....

That's right kids... no more parsing obscure, often changed output columns with your favorite bash/awk/python/magic.

Why IBM would not document this is beyond me,
