Manipulate all rows except header, but header should be output as well
Hello There...
I have a sample input file ..
I will be doing some manipulations on all the records except the header, but the header should always be at the top in the output. I want the file to be sorted (asc order on 1st field) and add 1000 as bonus to the field 3 (e.g. 125.23 + 1000).
I tried below:
awk 'BEGIN{FS=OFS=":"}{if( NR != 1){$3+=1000}print}' file
How can I sort the file? I know I could use sort but how can I sort all rows except the header and header should appear in sorted output?
I am thinking of doing something like this sort file | awk...
I would like to remove some lines from begining of file (header) and some lines from end of file (footer).
The header/footer lines generated by web-browser when the user upload a file to my webserver.

Hi,
I have an input like this

I would like to count the no. of columns and print a header with a prefix "Col".
I would also like to count the no. of rows and print as first column with each line number with a prefix "Row"
So, my output would be

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.
