Linux: remove last comma

The very last item should not end in a comma:
df | awk '! /[Ff]ilesystem/ {sub("%","",$5); print"\""$1"\":"$5"," }'| sed 's/^,*//g'

Open in new window

I can't be totally sure what you are doing, but if you are using

sed 's/^,*//g'

that will remove a leading comma, but not a trailing comma. Try

sed 's/,*$//g'

That removes ALL commas.  I need valid JSON so I only want the very last comma to be removed.
