shc is a shellscript compiler that converts shell scripts into executable binaries. It enhances script security by obfuscating the source code, making it useful for distributing proprietary scripts.
The scbind software is a shellscript "compiler" -- it does not actually compile scripts to machine code, but encodes them into executable images. The shell still runs the actual code. Prevents modifications/prying. Handles perl, awk, etc. also.
