shc - Shell script compiler
SHC is a generic shell script compiler. It takes a script, which is
specified on the command line and produces C source code. The generated
source code is then compiled and linked to produce a stripped binary.
The compiled binary will still be dependent on the shell specified in
the first line of the shell code (i.e shebang: #!/bin/sh or such), thus
shc does not create completely independent binaries.
shc itself is not a compiler such as cc, it rather encodes and encrypts
a shell script and generates C source code with the added expiration
capability. It then uses the system compiler to compile a stripped
binary which behaves exactly like the original script. Upon execution,
the compiled binary will decrypt and execute the code with the shells'
-c option.
