A sample output

<Snip>

My output from the script was a bit wrong because I have an NFS share
mounted:

davjam@moray:~> df-h
donnas.davjam.org:/videos 466G 193G 273G 42% /mounts/donnas/videos

All in TB 1.12T .66T .46T 58% @moray x86_64
-------------------------------------------------------------------

So, with a "little" tweaking to sort this out, drop the requirement for
a temporary file, and to make some cosmetic changes to the output, I now
get this:

davjam@moray:~> df-h

My tweaked script is now this:

#!/bin/bash

# Personalized `df -h` with totals
LINE="-------------------------------------------------------------------"
TMPF=$(df -hP|grep -v "Mounted on")

function max_columns
{
COLS="0"
local STRING
while [ $# -gt 0 ]
do
STRING=$1
COLS=$(( ${#STRING}>${COLS} ? ${#STRING} : ${COLS} ))
shift
done
}

max_columns ${TMPF}

printf "%-${COLS}s\t%8s%8s%8s%8s %-s\n" "Filesystem" "Size" "Used" "Avail" "Use%" "Mounted on"

# cat $TMPF
# Uncomment previous and comment the next two
# if df -h is not shown correctly

function do_columns
{
local DEVICE
local SIZE
local USED
local AVAIL
local PERC
local WHERE

while [ "$#" -gt 0 ]
do
DEVICE=$1 ; shift
SIZE=$1 ; shift
USED=$1 ; shift
AVAIL=$1 ; shift
PERC=$1 ; shift
WHERE=$1 ; shift
printf "%-${COLS}s\t%8s%8s%8s%8s %-s\n" "${DEVICE}" "${SIZE}" "${USED}" "${AVAIL}" "${PERC}" "${WHERE}"
done
}

do_columns $(echo "${TMPF}" | egrep -v '^/|@' |sort)
do_columns $(echo "${TMPF}" | egrep '^/|@' |sort)
# The showing of the total information

TMPF=$(df -P)
echo $LINE

# Get the sizes and percentage
SIZE=$(echo "${TMPF}" | egrep '^\/dev|@' |awk '{t2 = t2 + $2}END{print t2}')
USED=$(echo "${TMPF}" | egrep '^\/dev|@' |awk '{t3 = t3 + $3}END{print t3}')
AVAI=$(echo "${TMPF}" | egrep '^\/dev|@' |awk '{t4 = t4 + $4}END{print t4}')
PERC=$(echo -e "${USED}*100/${SIZE}\nquit"|bc)

# Set in GB
SIZE=$(echo -e "$SIZE/(1024*1024)\nquit"|bc)
USED=$(echo -e "$USED/(1024*1024)\nquit"|bc)
AVAI=$(echo -e "$AVAI/(1024*1024)\nquit"|bc)
printf "%-${COLS}s\t%8s%8s%8s\n" "All in GB" "${SIZE}G" "${USED}G" "${AVAI}G"

#Set in TB
SIZE=$(echo -e "scale=2\n$SIZE/1024\nquit"|bc)
USED=$(echo -e "scale=2\n$USED/1024\nquit"|bc)
AVAI=$(echo -e "scale=2\n$AVAI/1024\nquit"|bc)
printf "%-${COLS}s\t%8s%8s%8s%8s %-s\n" "All in TB" "${SIZE}T" "${USED}T" "${AVAI}T" "${PERC}%" "@$(uname -mn)"
echo ${LINE}
