Generating files of specific size - Shell Programming and Scripting

It depends on where you want to add the filename in the output file, but look at this:

Code:

#!/bin/ksh

awk -F/ '{print $1,$2,$3}' os_listing.out | while read filesize dirname filename; do
        mkdir $dirname
        cd $dirname
        echo $filename $filesize > $filename
        count=$(($filesize-${#filename}))
        dd if=/tmp/inputfile of=$filename bs=1 count=$count seek=${#filename}
        cd ..
done

This code adds the filename to the beginning of the file and then appends (count-length_of_filename) characters from the input file.
