Thanks all for sharing the information.

now i am able to get the required output.
Output :

mounted:"/boot" type:"part" file_system:"/dev/sda1"

mounted:"/" type:"lvm" file_system:"/dev/mapper/centos-root"

mounted:"[SWAP]" type:"lvm" file_system:"/dev/mapper/centos-swap"

mounted:"/" type:"lvm" file_system:"/dev/mapper/centos-root"


below is my df -h output
which is stored in
FILE1=/tmp/d4 file as below

Filesystem Size Used Avail Use% Mounted on
devtmpfs 1.9G 0 1.9G 0% /dev
tmpfs 1.9G 0 1.9G 0% /dev/shm
tmpfs 1.9G 176M 1.7G 10% /run
tmpfs 1.9G 0 1.9G 0% /sys/fs/cgroup
/dev/mapper/centos-root 57G 48G 9.3G 84% /
/dev/sda1 497M 217M 281M 44% /boot
tmpfs 379M 0 379M 0% /run/user/0

simultaneously i want to read another file which contains df -h ouput. and want to compare the Filesystem field with $NAME field in above ouput
if both are same then i want to add remaining fields of df -h output to current ouput

Example :
if file_system:"/dev/mapper/centos-root" is equal to df -h ouput "/dev/mapper/centos-root"

then for the current ouput
mounted:"/" type:"lvm" file_system:"/dev/mapper/centos-root" i want to add remaining df -h field output.

desired output :
mounted:"/" type:"lvm" file_system:"/dev/mapper/centos-root" Avail:"9.3G " Use%:"84%"

used below script :

#!/bin/bash
FILE=/tmp/d5
FILE1=/tmp/d4
while read LINE;
do . <(echo $LINE)
if [ "$MOUNTPOINT" != "" ]

mounted=$MOUNTPOINT

file_system=$NAME
type=$TYPE


while read LINE1;
do . <(echo $LINE1)

File_System=$Filesystem
if [ "$MOUNTPOINT" == "$Filesystem" ];then

echo -e "mounted:$MOUNTPOINT type:$type file_system:$Filesystem avail:$Avail \n"

done < FILE1

fi
fi
done < $FILE


./zzz: line 22: syntax error near unexpected token `done'
./zzz: line 22: `done < FILE1'

systemd-gpt-auto-generator

SYSTEMD-GPT-AUTO-GENERATOR(8)				    systemd-gpt-auto-generator				     SYSTEMD-GPT-AUTO-GENERATOR(8)

NAME

       systemd-gpt-auto-generator - Generator for automatically discovering and mounting root, /home and /srv partitions, as well as discovering
       and enabling swap partitions, based on GPT partition type GUIDs.

SYNOPSIS

       /lib/systemd/system-generators/systemd-gpt-auto-generator

DESCRIPTION

       systemd-gpt-auto-generator is a unit generator that automatically discovers root, /home, /srv and swap partitions and creates mount and
       swap units for them, based on the partition type GUIDs of GUID partition tables (GPT). It implements the Discoverable Partitions
       Specification[1]. Note that this generator has no effect on non-GPT systems, or where the directories under the mount points are already
       non-empty. Also, on systems where the units are explicitly configured (for example, listed in fstab(5)), the units this generator creates
       are overridden, but additional implicit dependencies might be created.

       This generator will only look for root partitions on the same physical disk the EFI System Partition (ESP) is located on. It will only look
       for the other partitions on the same physical disk the root file system is located on. These partitions will not be searched on systems
       where the root file system is distributed on multiple disks, for example via btrfs RAID.

       systemd-gpt-auto-generator is useful for centralizing file system configuration in the partition table and making manual configuration in
       /etc/fstab or suchlike unnecessary.

       This generator looks for the partitions based on their partition type GUID. The following partition type GUIDs are identified:

       |				     |				      | the root partition is located on is  |

       +-------------------------------------+--------------------------------+--------------------------------------+

       The /home and /srv partitions may be encrypted in LUKS format. In this case, a device mapper device is set up under the names
       /dev/mapper/home and /dev/mapper/srv. Note that this might create conflicts if the same partition is listed in /etc/crypttab with a
       different device mapper device name.

       Mount and automount units for the EFI System Partition (ESP) are generated on EFI systems. The ESP is mounted to /boot, unless a mount
       point directory /efi exists, in which case it is mounted there. Since this generator creates an automount unit, the mount will only be
       activated on-demand, when accessed. On systems where /boot (or /efi if it exists) is an explicitly configured mount (for example, listed in
       fstab(5)) or where the /boot (or /efi) mount point is non-empty, no mount units are generated.

       When using this generator in conjunction with btrfs file systems, make sure to set the correct default subvolumes on them, using btrfs
       subvolume set-default.

       systemd-gpt-auto-generator implements systemd.generator(7).
