The cat here is redundant, awk can read the file directly:

	pcr_aggregate="$(awk '{print $1}' tmp.txt)"

Same here:

	lineno="$(awk '{print $2}' tmp.txt)"

> +		tst_res TPASS "aggregate PCR value matched real PCR value (line: $lineno/$total_measurements)"

This line is about 100 columns wide. LTP shell style asks for lines
under 80 characters; perhaps wrap it or shorten the message.

Verdict - Needs revision
