如何将包装脚本附加到二进制文件？

Question

I have an executable say a.out. What I want to do is to attach a wrapper script to this executable which does a few things and then calls a.out. However, I would like to just have one file which I can distribute instead of two files. Any suggestions on how to do this?

I'm not terribly concerned about portability. Any solution that uses bash, perl or python is preferred but any scripting language would do.

Answer 1

#!/bin/bash

echo "Do few things before calling a.out"
/path/to/a.out 
echo "Done calling a.out"

Answer 2

您可以将a.out追加到包装脚本中（在bash中exit或在Perl中exit __END__之后），这会将其从自身提取到新文件中，更改其权限并运行它。
