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.
