I want to calculate the average line by line of some files with several lines on them, the files are identical, just want to average the 3rd columns of those files.
Example file:
001 0.046 Average of the nth line from the two files
001 0.047 Average of the nth line from the two files
001 0.048 Average of the nth line from the two files
001 0.049 Average of the nth line from the two files
002 0.000 Average of the nth line from the two files
002 0.001 Average of the nth line from the two files
002 0.002 Average of the nth line from the two files
002 0.003 Average of the nth line from the two files
002 0.004 Average of the nth line from the two files

My old school way is a one liner. And will search for average from SAR, to get the data receive rate. But, I dont think it is practical or accurate,. Because it calculates to off peak hours.

grep
GREP(1) General Commands Manual GREP(1)NAME
grep - search a file for a pattern
SYNOPSIS
grep [ option ... ] pattern [ file ... ]
DESCRIPTION
Grep searches the input files (standard input default) for lines (with newlines excluded) that match the pattern, a regular expression as
defined in regexp(6). Normally, each line matching the pattern is `selected', and each selected line is copied to the standard output.
The options are
-c Print only a count of matching lines.
-h Do not print file name tags (headers) with output lines.
-i Ignore alphabetic case distinctions. The implementation folds into lower case all letters in the pattern and input before interpre-
tation. Matched lines are printed in their original form.
-l (ell) Print the names of files with selected lines; don't print the lines.
-L Print the names of files with no selected lines; the converse of -l.
-n Mark each printed line with its line number counted in its file.
-s Produce no output, but return status.
-v Reverse: print lines that do not match the pattern.
Output lines are tagged by file name when there is more than one input file. (To force this tagging, include /dev/null as a file name
argument.)
Care should be taken when using the shell metacharacters $*[^|()= and newline in pattern; it is safest to enclose the entire expression in
single quotes '...'.

Exit status is null if any lines are selected, or non-null when no lines are selected or an error occurs.
