Please explain to us what you are trying to do. If you are going to use
awk, there is probably no need to also use
ex,
cut, and two invocations of
sed. I'm almost positive that the REs you are using in your search patterns are not doing what you think they are doing (and could match strings that you don't intend for them to match).
An immediate problem is that shell variables are not expanded inside single quoted strings. You could try, using double quotes (
") instead of single quotes (
') around the operand in the last
sed invocation in your command line and it might work; but unless you intend for all of the <period>s in your REs to match any character (not just a <period>), your command line might not work reliably.
