Question

I need a shell script to find and replace text that would go like:

For each line in a file
  find equation mark "="
  remove everything up to the equation mark on that line and replace it with the string cuts[Counter] where Counter counts how many times such substitutions have been made.

Could anybody help me out with getting started with a script like that?

Answer 1

Assuming you mean “up to the first equation mark…” and you want to keep the =, this should do it:

awk '{c += sub(/[^=]+=/,"cuts["c+0"]=") }1' file
