Custom df (diskfree) column output in Solaris using nawk

Let's say you want to combine some features of "df -h" with "df -n" to show filesystem type and some other custom modifications to the output. This is where awk/nakw/gawk/whatever come in handy:

% df -g | nawk '{if (NR % 5 == 1) printf "%-22s", $1 ; if (NR % 5 == 4) printf "%-10s", "fstype " $1 "\n"; if (NR % 5 == 2) printf "%-30s",$1/2/1024/1024 " GB"; if (NR % 5 == 2) printf "%-30s", $4/2/1024/1024 " GB free "}'

You can also add a comma (,) to the separators and output > csv (you can open the comma separated values table in Excel or OpenOffice or any other Spreadsheet application) :-).
