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.

Install:

./configure
make
sudo make install
or simply run the binary file provided, in bin/x32 or bin/x64 in terminal
./shc options

For Ubuntu

sudo add-apt-repository -y ppa:neurobin/ppa
sudo apt-get update
sudo apt-get install shc

Testing:

cd to test "directory"...
cd test
shc -f test.bash -o test
output binary file will be test. If no output file is specified by the -o option, then it will create an executable with .x extension by default

Known bugs:

The one (and I hope the only) limitation using shc is the _SC_ARG_MAX system configuration parameter. It limits the maximum length of the arguments to the exec function, limiting the maximum length of the runnable script of shc. !! - CHECK YOUR RESULTS CAREFULLY BEFORE USING - !!
