Help with scripting issue ...

[MikeL_4]

I am issuing a setboot command to capture my Primary and Secondary boot devices which I am interested in the following lines:

Primary bootpath : 0/0/0/2/0/0/0.0x0.0x1010000c0000000 (/dev/rdisk/disk2)
HA Alternate bootpath : 0/0/0/2/0/0/0.0x0.0x1000000c0000000 (/dev/rdisk/disk3)

From this is there a way in a script to pick out just the 'disk2' and 'disk3' from each line ??

Hi:

One quick way:

# setboot | perl -nle 'm{rdisk/(\w+)} and print $1'

 Regards!

And I *always* think Perl first :-)

To assign kudos, you need to explictly toggle them.  Marking a post as "solved" [which is a very appropriate thing to do] is a *separate* action.

You could also use sed to select the token between "rdisk/" and ")".  Something like:

sed -e '/rdisk/ s:.*rdisk/\([^)]*\)):\1:' file

Actually some slight changes:

sed -n -e '/rdisk/ { s:.*rdisk/\([^)]*\)):\1:; p; }' file
