I have a File under Linux /tmp/volume.log and the content is:

[id:1091666, name:root, deviceName:/dev/sda, maxStorage:107374182400, unitNumber:0, displayOrder:0, rootVolume:true],[id:1091851, name:/var/log/devops|40GB;/home/devops|150GB, deviceName:/dev/sdb, maxStorage:289910292480, unitNumber:1, displayOrder:1, rootVolume:false]],

It will be in single line. This file is generated by some other script.

My Aim is to find the non-root volume disk and parse it to LVM Commands as Variable to extend or create new volumes, at the time of OS Build.

In the above Example.

There are two disks,
1 - sda which is root disk, (if rootVolume is true it is root disk)
2 - sdb which is non root disk (if rootVolume is false it is non root disk)

I have to grep only

rootVolume=false

and grep then

deviceName:/dev/sdb

followed by:

name:/var/log/devops|40GB;/home/devops|150GB

Once I parse all the above in to Variables, I can call those variables in the Commands like

#!/bin/bash
Disk_name=/dev/sdb
Size_Value=40G
LV_name=var_log_devops
Mount_Point=/var/log/devops

sudo pvcreate $Disk_name
sudo vgcreate vgrp01 $Disk_name 

sudo lvcreate -L $Size_Value -n $var_log_devops vgrp01
sudo mkfs.xfs $var_log_devops
sudo mkdir -p $/var/log/devops
sudo mount $var_log_devops $/var/log/devops

Right now I am struck with, Extracting the Values from the Text file, becasue they are in single line and multiple Delimiters are present.

You can use the command cut something like:

cat /tmp/volume.log | cut -d, -f14 | tr -d "]]"
rootVolume=false

make it a variable:
rootvolume=$(cat /tmp/volume.log | cut -d, -f14 | tr -d "]]")

cat /tmp/volume.log | cut -d, -f3
deviceName:/dev/sda

cat /tmp/volume.log | cut -d, -f9
name:/var/log/devops|40GB;/home/devops|150GB

I gave you an example of the text file, but in real we might have more disk's. So I have to grep only the rootvolume=false and once the match is found. Then I need to get the false boot disk name. Then the other partition.

Hi @user3179298. You can change -f14 to match the information you want in the file. Does this make sense?

Hello Gora, the Field will change server to server. Some times the field 14 will have root volume disk.

I have a logic, but not sure how to get that done. i see every disk are start and end with [ ..... ],[.....],[.....] So, i need to grep for root volume=false, then need to take that [......rootvolume=false ] as variable and use sed or cut to get the disk and other volume information's. then i will parse it to the script for LVM creation.

How far would this get you:

awk -vRS="]" '/rootVolume:false/ for (i=1; i<=NF; i++) if ($i ~ /name' file
name:/var/log/devops|40GB;/home/devops|150GB,
deviceName:/dev/sdb,

It splits the single line at ], then scans through all fields to find the target ones, and prints them. You could read the result into shell variables like so, then:

read VARA VARB REST <<< $(awk -vRS="],*" -vORS=" " '/rootVolume:false/ for (i=1; i<=NF; i++) if ($i ~ /name' file)

How far would this get you:

awk -vRS="]" '/rootVolume:false/ for (i=1; i<=NF; i++) if ($i ~ /name' file
name:/var/log/devops|40GB;/home/devops|150GB,
deviceName:/dev/sdb,

It splits the single line at ], then scans through all fields to find the target ones, and prints them. You could read the result into shell variables like so, then:

read VARA VARB REST <<< $(awk -vRS="],*" -vORS=" " '/rootVolume:false/ for (i=1; i<=NF; i++) if ($i ~ /name' file)
echo $VARA
