C tool to scan for a pattern in a file. Uses the formatting AA BB ?? DD so you don't need to create a separate mask. Shows all results, and optionally shows an extra amount of bytes per result.
Usage:
./psc file "AA BB ?? DD"
or if you want to quickly peek x amount of bytes:
./psc file "AA BB ?? DD" 16
which shows 16 bytes + pattern length at each result.
