I created a backup script that emails all the admins when the backup is complete and attaches a log file of what what backed up. On occasion, something happens in which the backups stop working, I started "grep"ing around /var/log/syslog and I usually find the smoking gun. My goal is to zcat /var/log/syslog* and egrep all the instances of an occurence on a date that an error occurred. So I began testing using:
Grabs Date
Now I want to simply use zcat and egrep the lines that contain that date.
I remove the backticks
I tried many combinations but cant seem to catch my error in usage. I want egrep to use "Oct 23" from variable "$err_date".

vgcfgbackup
VGCFGBACKUP(8) System Manager's Manual VGCFGBACKUP(8)NAME
vgcfgbackup - backup volume group descriptor area
SYNOPSIS
vgcfgbackup [-d|--debug] [-f|--file filename] [-h|--help] [--ignorelockingfailure] [-P|--partial] [-v|--verbose] [VolumeGroupName...]
DESCRIPTION
vgcfgbackup allows you to backup the metadata of your volume groups. If you don't name any volume groups on the command line, all of them
will be backed up.
In a default installation, each volume group gets backed up into a separate file bearing the name of the volume group in the directory
/etc/lvm/backup. You can write the backup to an alternative file using -f. In this case if you are backing up more than one volume group
the filename is treated as a template, and %s gets replaced by the volume group name.
NB. This DOESN'T backup user/system data in logical volume(s)! Backup /etc/lvm regularly too.
OPTIONS
See lvm for common options.
