Just ran into an interesting bug in 9.3P17 (yes, I'm off support!) and another 9.5P5 system which I thought I'd share.
Let's grab all the export policies on the system in CSV format to make it easy to parse:
ntap1::> set -showseparator ","; export-policy show
Vserver Policy Name --------------- ------------------- foo default
WTF? That's wierd? Let's try something else:
ntap1::> set -showseparator ","; export-policy show -fields vserver ,policyname
vserver,policyname, Vserver,Policy Name, foo,default,
Ah! Now we're getting what we want. Stupid annoying bug when you're trying to write a perl script to pull out data. Can anyone confirm if this is still there in the latest releases?
Hmm... poking at it some more... I suspect I'm forgetting that you *must* specify the fields when changing the -showseparator to get easier to parse output. But I still think this is a surprising occurance, since it does include the field names, so there's no need to actually specify them in the output.
Principal of least surprise and all that.
Cheers, John
Just tried in 9.7P11
knoxsahrc09l99::> set -showseparator ","
knoxsahrc09l99::> export-policy show Vserver Policy Name --------------- ------------------- esxi_boot default
knoxsahrc09l99::> set -showseparator "--"
knoxsahrc09l99::> export-policy show Vserver Policy Name --------------- ------------------- esxi_boot default
knoxsahrc09l99::> export-policy show -fields vserver ,policyname vserver--policyname-- Vserver--Policy Name-- esxi_boot--default--
knoxsahrc09l99::> set -showseparator " "
knoxsahrc09l99::> export-policy show -fields vserver ,policyname vserver policyname --------- ---------- esxi_boot default

Thanks for checking, I think it's a bug myself... but I can see how it might be considered a feature of some sort.
