I'm converting decimal to integer with bc, and I'd like to assign the integer output from bc to a variable 'val'.
E.g. In the code below: If b is 5000.000, lines 6 and 8 will output:
5000
(5000.000+0.5)/1 | bc
I'd like val to take the value 5000 though, rather than 5000.000

vgrename
VGRENAME(8) System Manager's Manual VGRENAME(8)NAME
vgrename - rename a volume group
SYNOPSIS
vgrename [-A|--autobackup y|n] [-d|--debug] [-h|-?|--help] [-t|--test] [-v|--verbose] OldVolumeGroup{Path|Name|UUID} NewVol-
umeGroup{Path|Name}
DESCRIPTION
vgrename renames an existing (see vgcreate(8) ) volume group from OldVolumeGroup{Name|Path|UUID} to NewVolumeGroup{Name|Path}.
OPTIONS
See lvm for common options.
Examples
"vgrename /dev/vg02 /dev/my_volume_group" renames existing volume group "vg02" to "my_volume_group".
"vgrename vg02 my_volume_group" does the same.
"vgrename Zvlifi-Ep3t-e0Ng-U42h-o0ye-KHu1-nl7Ns4 VolGroup00_tmp" changes the name of the Volume Group with UUID Zvlifi-Ep3t-e0Ng-U42h-o0ye-
KHu1-nl7Ns4 to "VolGroup00_tmp".
All the Volume Groups visible to a system need to have different names. Otherwise many LVM2 commands will refuse to run or give warning
messages.
This situation could arise when disks are moved between machines. If a disk is connected and it contains a Volume Group with the same name
as the Volume Group containing your root filesystem the machine might not even boot correctly. However, the two Volume Groups should have
different UUIDs (unless the disk was cloned) so you can rename one of the conflicting Volume Groups with vgrename.
