Hi,

Test next 'perl' script:

Code:
$ perl -ne 'BEGIN { open $f31, ">", "31.txt" or die $!; open $f39, ">", "39.txt" or die $!; } ($a) = unpack "x154 A2", $_; if ($a == 31) { print $f31 $_; } elsif ($a == 39) { print $f39 $_; }' infile

Birei

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
