[SOLVED] Delimiting transactions in a text file with bash

Issue

I've got a text file with the following pattern:

06:52:25 -> TRANSACTION START
06:52:26 - line1
06:52:27 - line2
06:52:29 -> TRANSACTION END*
06:53:24 -> TRANSACTION START
06:53:25 - line3
06:53:40 - line4
06:53:52 -> TRANSACTION END

I would like to separate every occurrence of starting transactions and ends into separate files

Solution

Try:

awk '/TRANSACTION START/{file="trans_"cont++".txt"}{print $0 >> file}' inputfile

Explanation:

/TRANSACTION START/{file="trans_"cont++".txt"}: When the START pattern is matched the target file name is updated.

{print $0 >> file}: Print every line in the current file with >> to avoid overwrite.
