Top Forums UNIX for Beginners Questions & Answers Bash script to get total size off of remainder calculated Post 303029593 by user3528 on Tuesday 29th of January 2019 10:33:24 AM

Thanks for the response. This is one of the pieces for my final script which I am building. The script's intended use is ./scriptname arg 1 arg2 arg3 arg4 from the command line. The arguments will get passed to the default bash variables ( $1 $2 $3 $4 etc.) hence I was using them in my statements. The use of bc is to future proof it if numbers are not integers but floating numbers.

NAME
pvdisplay - display attributes of a physical volume SYNOPSIS
pvdisplay [-c|--colon] [-d|--debug] [-h|-?|--help] [-s|--short] [-v[v]|--verbose [--verbose]] PhysicalVolumePath [PhysicalVolumePath...] DESCRIPTION
pvdisplay allows you to see the attributes of one or more physical volumes like size, physical extent size, space used for the volume group descriptor area and so on. pvs (8) is an alternative that provides the same information in the style of ps (1). OPTIONS

The values are: * physical volume device name * volume group name * physical volume size in kilobytes * internal physical volume number (obsolete) * physical volume status * physical volume (not) allocatable * current number of logical volumes on this physical volume * physical extent size in kilobytes * total number of physical extents * free number of physical extents * allocated number of physical extents -s, --short Only display the size of the given physical volumes. -m, --maps Display the mapping of physical extents to logical volumes and logical extents.
