This is a very specific example. I found this tricky because regular expressions in sed isn’t the same as in Perl.

I wanted to take output from the format command in Solaris and just get a list of disks on the system.

I ran format and redirected the output to a file called disks.txt

– file: disks.txt –

0. c0t0d0
/pci@1f,4000/scsi@3/sd@0,0
1. c0t1d0
/pci@1f,4000/scsi@3/sd@1,0
2. c1t32d0
/pci@1f,4000/SUNW,qlc@2/fp@0,0/ssd@w21000004cf8ab02c,0
3. c1t33d0
/pci@1f,4000/SUNW,qlc@2/fp@0,0/ssd@w21000004cfb448ed,0
4. c1t34d0
/pci@1f,4000/SUNW,qlc@2/fp@0,0/ssd@w21000004cf70fd3f,0
5. c1t35d0
/pci@1f,4000/SUNW,qlc@2/fp@0,0/ssd@w21000004cfa6efc4,0


Then I wanted just the ‘ctd’ names of these disks (ie: c1t35d0 being the last one).

– magical sed trick –

cat disks.txt | sed -n 's/\(.*\)\(c[0-9]*t[0-9]*d[0-9]*\)\(.*\)/\2/p'


This should output:

c0t0d0
c0t1d0
c1t32d0
c1t33d0
c1t34d0
c1t35d0


The one thing I can’t figure out is how to run format in a non-interactive way for scripting. It seems you have to resort to using the path_to_inst file. I did something like this in my humble project easylun.
