Get hard drive model name with bash - bash

Question

I want to get the various model names of my hard drives using bash.
I can do it if there's just one, using hwinfo like this:
hwinfo --ide|grep Model|sed -ne '/Model/s/.*Model: "\([^"]*\)".*/\1/p'
But this obviously fails when there's more than one. One regular hwinfo output when there are several hard drives is this:
[faidoc#Delorean ~]$ hwinfo --ide

Every drive begans with for example "11:" or "12:" so if I could get one at a time that will be the solution.
Any ideas?
Thanks

Answer 1

You can get the info with:
hdparm -i /dev/sda | grep -i model
or, if you want just the model name:
hdparm -i /dev/sda | perl -n -e 'print "$1\n" if (m/model=(.+?),/i);'

Answer 2

If you know which one you want a very easy way would be grep -A8 -E '^11:'
hwinfo --ide|grep -A8 -E '^11:'|grep Model|sed -ne '/Model/s/.*Model: "\([^"]*\)".*/\1/p'
The -A flag on grep grabs that many lines "After" the match as well as the line with the match.
There's also -B for "Before" and -C for "Context"

Answer 3

here's a quick and dirty awk statement that may help:
hwinfo --ide | awk '{ if($2=="IDE"){ide=$3} if($1=="Model:"){print "IDE " ide $0} }'
basically searches for the pattern "IDE" in the second word of each line.
if it finds that, it stores the third word of the line in the variable named "ide".
then it searches the first word of each line for "Model:".
if found, it prints the IDE it stored earlier and the whole line containing the model name.
so you end up with the name and IDE location in your output:
IDE 200.0: Model: "VBOX HARDDISK"
IDE 300.0: Model: "VBOX HARDDISK"
and it should work no matter how many disks are attached.
