There's no mention of what syspatch(8) returns, in the manpage.
I can prove quickly enough that it exits(0) when there's nothing to
do, but
I'm more interested in knowing (for automation purposes) what the
return
values are in other circumstances, and all my systems are already up
to
date. Before standing up yet another system, I figured I'd ask here.
I can think of four scenarios syspatch(8) perhaps ought to
distinguish, at
least I'm interested in these 4 outcomes:
1. nothing to do
2. patches waiting, but didn't do anthing
3. patches applied
4. something went wrong
Can I reliably tell based on $? or do I have to parse the output?
Most likely parse, yes.
"patches waiting, but didn't do anything" might be interesting (i.e
patches are
available); dunno...
Equally if not more interesting would be "I tried to apply patches but
failed somehow". Which happened to me, and which is why I asked in the
first place.
*sigh* I'll try to propose some bad diffs [if I'm writing them, they'll
be bad] someday soon.
