tmarikle,
I now have and get back. What do I have wrong?

$ var_2=3
$ print "11 10 9 8 7 6 5 4 3 2 1" | awk -v var_2=$var_2 '{gsub(/var_2/," ",$0);print}'
11 10 9 8 7 6 5 4 3 2 1

I can't get this to work. I'm not use to stringing thing together and my scripts have been simple sed types. Sorry for all the notes but indeed thanks very much for the help.

John

Sorry, /var_2/ was treated as a literal.

Code:
$ var_2=3
$ print "11 10 9 8 7 6 5 4 3 2 1" | nawk -v var_2=$var_2 '{gsub(" "var_2" "," ",$0);print}'
11 10 9 8 7 6 5 4 2 1

11 10 9 8 7 6 5 4 2 1
it won't work for 'var_2=1' or 'var_2='11'

True, I would have to add a space before the 11 and after the 1.
