CPU & Memory Parsing String
Hi,

I am trying to do the following in Linux:

I have some text as follows:
/home/user/backup/scripts/SDW/sql/backup.sql

which needs to be parsed:
to pick up "backup"

So, pick up text after the last '/' until '.' from a string.

Can someone please tell me how can I do that?

Thanks,
thinksys

vgcfgrestore

VGCFGRESTORE(8)                                               System Manager's Manual                                              VGCFGRESTORE(8)

NAME

       vgcfgrestore - restore volume group descriptor area

SYNOPSIS

       vgcfgrestore [-d|--debug] [-f|--file filename] [-l[l]|--list] [-h|--help] [-M|--Metadatatype1|2] [-t|--test] [-v|--verbose] VolumeGroupName

DESCRIPTION

       vgcfgrestore  allows  you  to  restore  the metadata of VolumeGroupName from a text backup file produced by vgcfgbackup.  You can specify a
       backup file with --file.  If no backup file is specified, the most recent one is used.  Use --list for a list of the available  backup  and
       archive files of VolumeGroupName.

OPTIONS

       -l | --list -- List files pertaining to VolumeGroupName
              List  metadata  backup  and  archive  files  pertaining  to VolumeGroupName.  May be used with the -f option.  Does not restore Vol-
              umeGroupName.

       -f | --file filename -- Name of LVM metadata backup file
              Specifies a metadata backup or archive file to be used for restoring VolumeGroupName.  Often this file has been created with  vgcfg-
              backup.

       See lvm for common options.

REPLACING PHYSICAL VOLUMES

       vgdisplay  --partial  --verbose will show you the UUIDs and sizes of any PVs that are no longer present.  If a PV in the VG is lost and you
       wish to substitute another of the same size, use pvcreate --restorefile filename --uuid uuid (plus additional arguments as appropriate)  to
       initialise  it with the same UUID as the missing PV.  Repeat for all other missing PVs in the VG.  Then use vgcfgrestore --file filename to
       restore the volume group's metadata.
