NR with $var?

[mrn]

Is this possible?

SPLIT=40

awk '{
if (NR % ${SPLIT})
printf ("%s #", $0)

NR doesn't seem to like the Var $SPLIT

I've seen examples like

NR % V1 ; V1=$SPLIT

but can't seem to get my head round it.

A starting point:
awk -v SPLIT=$PLIT '{
if (NR % SPLIT)printf ("%s #", $0)
...

Hope This Helps, PH.

In other words... awk variables are not shell variables. If you were to surround your awk script in single-quotes instead of double-quotes then the shell would interpolate them into the script (which may be what you have seen elsewhere), however this can be awkward because it means escaping any other characters which you need to be preservd for awk, for example \$0.

There's a typo in PHV's post, PLIT should of course be SPLIT.
