[Chester LUG] Help with a bash script

[Stuart Burns]

Hi everyone,

I am hoping someone can help me a bit here. I am creating a cript that
deals with volume groups. However my bash skills fall short.

I have a file that looks like this

Vg955-01 /dev/diska1
Vg955-01 /dev/diska2
Vg978-01 /dev/disk45
Vg978-04 /dev/disk13

You get the picture.

Now what I am trying to do is get all the vg parts followed by the
constituent disks. Ie above should look like:

Vg955-01 /dev/disk1a /dev/diska2
Vg978-01 /dev/disk45
Vg978-04 /dev/disk13

I cant really think of an easy way to do it without resorting to perl.
Can anyone help?

Regards

Stu
