Binary files are just that - all possible acsii characters from 0 - 255

awk is not meant to read binary files, it is meant to read carriage control, human readable files. Because one version "works" and another does not is not unexpected because awk is NOT meant to work well with your data. sed is not guaranteed to work with that kind of data either.

There are tools that will work. What are you trying to do? count bytes in a file?

NAME
igawk - gawk with include files SYNOPSIS
igawk [ all gawk options ] -f program-file [ -- ] file ... igawk [ all gawk options ] [ -- ] program-text file ... DESCRIPTION
Igawk is a simple shell script that adds the ability to have ``include files'' to gawk(1). AWK programs for igawk are the same as for gawk, except that, in addition, you may have lines like @include getopt.awk in your program to include the file getopt.awk from either the current directory or one of the other directories in the search path. OPTIONS
See gawk(1) for a full description of the AWK language and the options that gawk supports. EXAMPLES
cat << EOF > test.awk @include getopt.awk BEGIN { while (getopt(ARGC, ARGV, "am:q") != -1) ... } EOF igawk -f test.awk SEE ALSO
