#!/bin/sh

# newdf - a friendlier version of df

sedscript="/tmp/newdf.$$"

trap "rm -f $sedscript" EXIT

cat << 'EOF' > $sedscript

function showunit(size)

{ mb = size / 1024; prettymb=(int(mb * 100)) / 100;

gb = mb / 1024; prettygb=(int(gb * 100)) / 100;

if ( substr(size,1,1) !~ "[0-9]" ||

substr(size,2,1) !~ "[0-9]" ) { return size }

else if ( mb < 1) { return size "K" }

else if ( gb < 1) { return prettymb "M" }

else { return prettygb "G" }

}

BEGIN {

printf "%-27s %7s %7s %7s %8s %-s\n",

"Filesystem", "Size", "Used", "Avail", "Capacity", "Mounted"

}

!/Filesystem/ {

size=showunit($2);

used=showunit($3);

avail=showunit($4);

printf "%-27s %7s %7s %7s %8s %-s\n",

$1, size, used, avail, $5, $6

}

EOF

df -k | gawk -f $sedscript

exit 0
