How to convert bash file to a binary executable

问题

I created a binary executable from bash script on linux server through SHC. The binary created works fine on linux machines, but through mistake on Mac. How could I convert my bash file to binary executable that is able to run everywhere(ubuntu, CentOS, Mac, Cygwin)?

    shc -v -r -T -f ir16fetcher.sh
    mv ir16fetcher.sh.x ir16fetcher

Shebang of my bash script

    #!/bin/bash

On Linux machines

    ./ir16installer 
    USAGE  : ir16fetcher <servername/ip address> [the n th latest build - optional. Default 1]
    EXAMPLE: ir16fetcher jagger 2
    EXAMPLE: ir16fetcher 167.116.6.155
    REQUIRE: Please make sure conf file in installation folder ~/IRinstall/ir16 & ~/IRinstall/irmanager

On my Mac

    ./ir16installer 
    -bash: ./ir16installer: cannot execute binary file

You will have to do this for every architecture and operating system you need to support. In any case, there doesn't really seem to be any benefits of using this method for distribution. It adds dependencies and complicates delivery, and I'm pretty sure whatever obfuscation the "shc" compiler implements is easily reversed.

I think it's not gonna work

"The compiled binary will still be dependent on the shell specified in the first line of the shell code (i.e. #!/bin/sh), thus shc does not create completely independent binaries."

if the goal here is to "hide" your source code, and then have the "hidden" copy of the code be executable on the Unix OSes you listed, then, encryption is really your only option.

I say this because encryption tools are available on every base Unix install. For your purposes, this is a very good thing as you wont have to download or configure anything additional. They're just there, as part of the natural installation of the OS. One of such tools is called openssl.

To Encrypt your file/script with openssl:

echo precious-content | openssl aes-128-cbc -a -salt -k mypassword
U2FsdGVkX1+K6tvItr9eEI4yC4nZPK8b6o4fc0DR/Vzh7HqpE96se8Fu/BhM314z

To Decrypt your file/script with openssl:

echo U2FsdGVkX1+K6tvItr9eEI4yC4nZPK8b6o4fc0DR/Vzh7HqpE96se8Fu/BhM314z | openssl aes-128-cbc -a -d -salt -k mypassword
precious-content

Now, to get openssl to do what you want it to do automatically without having to spend hours of your own time figuring out a way, you can paste your script to a site like www.EnScryption.com. This site will generate an "executable" version of your code for you, which you can then run on any Mac, Ubuntu, RedHat, CentOS box.
