in thread Searching binary data

After some coersion, your response led me down the proper path. Here's my updated code snippet:

my $match = pack 'H*', '53005f00560045005200530049004f004e005f004' . '9004e0046004f0000000000bd04effe00000100'; open(FILE,$file) or die $!; while (<FILE>) { if (/$match(\S{2})(\S{2})(\S{2})(\S{2})/) { print "Found match!"; print join('.',map {unpack 'H*',$_; } ($1,$2,$3,$4); } } close(FILE);
I think my confusion rested in how perl would handle a binary file. Seems that the DWIM held true... I was making it harder than it was.

Thanks for your help!

Cheers,
Shendal
