netstat -a | grep -w 9071 |grep ESTABLISHED | awk '{print $5}' | cut -d'.' -f1

Only if the closing EOF is indented with a TAB (or nothing at all - it won't work if those are spaces before it).

Doubtless you can simplify the code further, i.e. by using awk to read both files and substitute the correct values. You would then write this to a temporary file and copy that over the original.

You could use use awk:

Hey,

You can just sum it up as you go through each line:

$ cat myScript
awk '{
TR=0
for( I = 1; I <= NF; I++ ) {
TR += $I
TC[I] += $I
printf( "%6d", $I )
}
print " = " TR...

$0 means 'the entire unmodified line', pure and simple. You can change what 'line' means to awk, but by default, it uses newlines like everything else.

You're making this much too hard on yourself. When you set a variable in the shell, parameter expansion occurs in double quoted strings and that is all you need here.
