Compare two files in UNIX
Hi,
I have two files
File1 Contents:
abc
dcf
sdc
File2 Contents:
dcf
sdc
erg
Now my program should return the contents existing in File1 but not in File2. In this case output shoud be "abc" as abc is not available in File 2. It should not return "erg" by saying it is existing in File2 and not in File1.
Only File1 Contents not existing in File2 should be displayed. Is there any command to solve this.
Appreciate you assistance in advance...

LEARN ABOUT V7
vgimportclone
VGIMPORTCLONE(8) System Manager's Manual VGIMPORTCLONE(8)
NAME
vgimportclone - import and rename duplicated volume group (e.g. a hardware snapshot)
SYNOPSIS
vgimportclone [-n|--basevgname VolumeGroupName] [-i|--import] PhysicalVolume [PhysicalVolume...]
DESCRIPTION
vgimportclone is used to import a duplicated VG (e.g. hardware snapshot). Duplicate VG(s) and PV(s) are not able to be used until they are
made to coexist with the origin VG(s) and PV(s). vgimportclone renames the VG associated with the specified PV(s) and changes the associ-
ated VG and PV UUIDs.
OPTIONS
See lvm for common options.
-n|--basevgname VolumeGroupName
By default the snapshot VG will be renamed to the original name plus a numeric suffix to avoid duplicate naming (e.g. 'test_vg'
would be renamed to 'test_vg1'). This option will override the base VG name that is used for all VG renames. If a VG already
exists with the specified name a numeric suffix will be added (like the previous example) to make it unique.
-i|--import
Import exported Volume Groups. Otherwise VGs that have been exported will not be changed (nor will their associated PVs).
ENVIRONMENT VARIABLES
LVM_BINARY
The LVM2 binary to use. Defaults to "lvm".
EXAMPLES
The origin VG vg00 has origin PVs /dev/sda and /dev/sdb and the respective snapshot PVs are /dev/sdc and /dev/sdd. To rename the VG asso-
ciated with /dev/sdc and /dev/sdd from vg00 to vg00_snap (and to change associated VG and PV UUIDs) do:
vgimportclone --basevgname vg00_snap /dev/sdc /dev/sdd
