I am using this code to insert something into a csv file:
awk -F";" -v url=$url -v nr=$nr 'NR==nr{$2=url$2}1' file
Why do I get the output
field1 field2
instead of
field1;field2
I have given -F";", so the field separator should surely be ";". (1 Reply)

pnmdepth
pnmdepth(1) General Commands Manual pnmdepth(1) NAME
pnmdepth - change the maxval in a portable anymap SYNOPSIS
pnmdepth newmaxval [pnmfile] DESCRIPTION
Reads a portable anymap as input. Scales all the pixel values, and writes out the image with the new maxval. Scaling the colors down to a smaller maxval will result in some loss of information. Be careful of off-by-one errors when choosing the new maxval. For instance, if you want the color values to be five bits wide, use a max- val of 31, not 32. One important use of pnmdepth is to convert a new format 2-byte-per-sample PNM file to the older 1-byte-per-sample format. Before April 2000, essentially all raw (binary) format PNM files had a maxval less than 256 and one byte per sample, and many programs may rely on that. If you specify a newmaxval less than 256, the resulting file should be readable by any program that worked with PNM files before April 2000. SEE ALSO
