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.
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 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.
