pros:
you retain the data so that you can analyse it later
capturing the data and analysis of data are separated
cons:
you may end up filling disk space with the data files
Actually, I want to do it all in one script so I can see the largest and smallest users simultaneously with the output. Thanks for the input, though. Any other ideas?

Hello,
I have often found bash to be difficult when it comes to floating point numbers. I have data with rows of tab delimited floating point numbers.

LAM(1) BSD General Commands Manual LAM(1)
NAME
lam -- laminate files
SYNOPSIS
lam [-f min.max] [-p min.max] [-s sepstring] [-t c] file ...
DESCRIPTION
lam copies the named files side by side onto the standard output. The n-th input lines from the input files are considered fragments of the
single long n-th output line into which they are assembled. The name ``-'' means the standard input, and may be repeated.
Normally, each option affects only the file after it. If the option letter is capitalized it affects all subsequent files until it appears
again uncapitalized. The options are described below.
-f min.max Print line fragments according to the format string min.max, where min is the minimum field width and max the maximum field
width. If min begins with a zero, zeros will be added to make up the field width, and if it begins with a '-', the fragment
will be left-adjusted within the field.
-p min.max Like -f, but pad this file's field when end-of-file is reached and other files are still active.
-s sepstring Print sepstring before printing line fragments from the next file. This option may appear after the last file.
-t c The input line terminator is c instead of a newline. The newline normally appended to each output line is omitted.
To print files simultaneously for easy viewing use pr(1).
EXAMPLES
The command
lam file1 file2 file3 file4
joins 4 files together along each line. To merge the lines from four different files use
lam file1 -S "
" file2 file3 file4
Every 2 lines of a file may be joined on one line with
lam - - < file
and a form letter with substitutions keyed by '@' can be done with
lam -t @ letter changes
