the file to search in $5 (the 11,137,660 line file)
So the expected output would be:
only $4, $5 where the match was found and the average of $7 are printed
Thank you very much .
In your code, you are saving $1 in a[] and $2 in b[] and at the end you are printing them with a colon between them. In you sample data above, $4 is always the same as $1:$2. Does that same relationship occur in all lines in your file? (Saving and printing $4 in an array will be faster than saving $1 in an array, saving $2 in another array, and printing both of them.) And, you say above that you want the output to be $4, $5, and the average, but you show the output being $4, $5, a "|", $6, and the average??? Please clarify!
Your sample output above shows that the average of 1, 2, and 3 is 3. Why not 2 (i.e., (1+2+3)/3)? How many decimal places do you want printed in the average?
Are your search strings always to be exactly matched by the string starting with the 1st character of $5 and ending with the character before the <minus-sign> character in $5? (Your script will run MUCH faster if you perform one test to determine if a string is a subscript in an array instead of an average of 14-130 regular expression matches.)

The below bash will untar each tar.bz2 folder in the directory, then remove the tar.bz2.
Each of the tar.bz2 folders ranges from 40-75GB and currently takes ~2 hours to extract. Is there a way to speed up the extraction process?
