Is there any way to source
(include) compiled script?
I use shc to compile all of my scripts and when I run them from the command line they work OK to
shc does not actually compile scripts. It merely obfuscates them by encrypting and embedding them inside a C program, so it cannot improve performance. The actual shell still interprets and executes the code and is required for the script to run.
If you absolutely must use this tool to obfuscate your code, you will have to combine everything into a single file.
