Even though the cut man page says
The order of bytes, characters or fields in the output will be identi-
cal to those in the input. With no FILE, or when FILE is -, read stan-
dard input.
But still I think
$ echo a,b,c,d|cut -d, -f 3,4
c,d
$ echo a,b,c,d|cut -d, -f 4,3
c,d
Is dumb. Add another switch to do rearranging. Yes,
awk -F, 'BEGIN{OFS=","};{print $4,$3}'
will work, but then of course the entire cut command could just be
made into a one line alias calling awk in the first place...
