Regex to list blkid Labels

Question

Apols but sure someone can provide this as regex just dont compute with me.

So say if I had this output from blkid if I wanted the UUID portion of the matching LABEL="Usb3Ext"

/dev/sda1: UUID="f2134523-0628-f8bd-359d-4f19069e2b6e" UUID_SUB="3e97c008-8038-bca2-5073-bfedb2e24ee8" LABEL="portal:1" TYPE="linux_raid_member" PARTUUID="e52e2353-01"

Answer 1

You can use awk like this:

blkid | awk '/LABEL="Usb3Ext"/{i=gensub(/.* UUID="(.*)".*/, "\\1", "g");print i}'

or sed:

blkid | sed '/LABEL="WINRE_DRV"/!d;s/.* UUID="\(.*\)".*/\1/'

Better would be to use lsblk:

lsblk -no LABEL,UUID | awk '$1 == "Usb3Ext" {print $2}'

Answer 2

Not too elegant, but it works (nevertheless where UUID ist showing up):

blkid | awk -F' UUID=\"' '{print $2}' | awk -F"\"" '{print $1}'
