If you have gawk and bash:

Code:
$ cat bits.awk
#!/bin/bash
echo $((16#$1)) | gawk ' {
for(i=lshift(1,31);i;i=rshift(i,1))
printf "%d%s", (and($1,i) > 0), ++c%4==0?" ":"";
printf"\n"; }'
 
$ ./bits.awk AFC92317
1010 1111 1100 1001 0010 0011 0001 0111
 
$ set -- $(./bits.awk AFC92317)
 
$ echo $4
1001

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
