further to Yoda, I think $0 would still contain as the original input record and performing maths would result on the integer part ( int($0) would return $1 ) in this case. (others please correct me here if this is not the case)
You have to play with RS
AFAIK, I guess multi-character RS is supported only by gnu awk ( though not very much sure).
Hi All,
I have a file like -
num.txt
12, 34, 65, line1
34, 65, 89, line2
43, 65, 77, line3
I want to do two things -
1. Add first three columns of each line and print the line with largest value.
i.e. (12+34+65) for 1st line and so on.
2. Add middle column of each line i.e.... (3 Replies)

Can anyone tell me how sum values in each record of a file and append that value to the end? For instance a typical record will be:
FY12,Budget,771100,,,,,,,,,250,-250
I'd like the record to become
FY12,Budget,771100,,,,,,,,,250,-250,0
which can be put into another file.
Thank you. (6 Replies)

I was just curious about how to sum the total file size of a certain type of file. For instance:
$find . -name "*.aif"
will print out the paths to each .aif file. Instead of printing, how could one sum the total space used by all of the aif files? Thanks!

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.
