A script to incrementally poll a log file of timestamp-prefixed text records

	#!/bin/bash

	#
	# A script to incrementally poll a log file.
	# Subsequent invocations print lines added since the previous invocation.
	# An assumption is that log lines begin with a timestamp 23 characters long (see/tweak the TS_LEN variable below).
	#
	# The state is stored in the file <original_filename>.seen as a last_line_no + last_timestamp pair last seen.
	# If the state file is not there, or the line_no in the target file has the last_timestamp
	# different from the one in the state file, then the file is printed from the line 1.
