No, a sample is not posted above. All that you have shown us is part of a page 3 and part of a page 4 of a sample of a single transaction. You have not shown us anything that contains "_Start", "_End", "Purchases and Adjustments", or any other string you say you're looking for (except for the "$").
It appears that you are asking us to help you produce an extremely inefficient way to separate statements into separate files or to discard unwanted text between statements and just print the statements from a file (or from multiple files) containing multiple statements. You say that only numbers follow the "$", but that is not true ("," and "." are not numbers). And why do we care? The only $ in the entire sample you have shown us is $ you want to find. So, my script gave you the line numbers of all lines containing a $. If there are multiple statements (or transactions) in your input file and you have set $start in your shell to be the 1st line of a transaction and you just want the line number of the 1st line after that that contains a $, try:

Code:

awk -F'$' -v low="$start" 'NF<2 || NR<low{next}{print NR; exit}' sample.txt

If you'd like us to help you create a script that will throw away everything between "transactions" or split "transactions" into separate files efficiently, then give us a real example and an accurate description of how to identfy the 1st and last lines of a "transaction", and then describe what you want to be done with the "transactions" found.
