With input files so big, it's more efficient to use join:
If the input files were not sorted, sort first before joining. The long list of fields after -o is to get rid of the trailing '|' from f1, otherwise, the whole -o... can be omitted.
Greetings, all. I've got a project that requires I join two data files together, then do some processing and output. Everything must be done in a shell script, using standard unix tools. The files look like the following:
File_1
Layout:

Hi guys,
I have three files which needs to be joined to a single file.
File 1:
Col a, Col b, Col c

Hi,
I have about 20 tab delimited text files that have non sequential numbering such as:
UCD2.summary.txt
UCD45.summary.txt
UCD56.summery.txt
The first column of each file has the same number of lines and content. The next 2 column have data points:
i.e UCD2.summary.txt:

ppmtosixel
ppmtosixel(1) General Commands Manual ppmtosixel(1)NAME
ppmtosixel - convert a portable pixmap into DEC sixel format
SYNOPSIS
ppmtosixel [-raw] [-margin] [ppmfile]
DESCRIPTION
Reads a portable pixmap as input. Produces sixel commands (SIX) as output. The output is formatted for color printing, e.g. for a DEC
LJ250 color inkjet printer.
If RGB values from the PPM file do not have maxval=100, the RGB values are rescaled. A printer control header and a color assignment table
begin the SIX file. Image data is written in a compressed format by default. A printer control footer ends the image file.
OPTIONS -raw If specified, each pixel will be explicitly described in the image file. If -raw is not specified, output will default to com-
pressed format in which identical adjacent pixels are replaced by "repeat pixel" commands. A raw file is often an order of magni-
tude larger than a compressed file and prints much slower.
-margin
If -margin is not specified, the image will be start at the left margin (of the window, paper, or whatever). If -margin is speci-
fied, a 1.5 inch left margin will offset the image.
PRINTING
Generally, sixel files must reach the printer unfiltered. Use the lpr -x option or cat filename > /dev/tty0?.
BUGS
Upon rescaling, truncation of the least significant bits of RGB values may result in poor color conversion. If the original PPM maxval was
greater than 100, rescaling also reduces the image depth. While the actual RGB values from the ppm file are more or less retained, the
color palette of the LJ250 may not match the colors on your screen. This seems to be a printer limitation.
