问题描述

是否有可能写一个bash脚本,这里面包含一个二进制可执行程序?

Is it possible to write a bash script, which would contain a binary executable program inside?

我的意思是一个脚本,它将包含一个文本形式的可执行文件,将被执行的时候这个脚本被倾倒回到一个可执行文件的转储?

I mean a script, which would contain a dump of an executable in a textual form, which will be dumped back to an executable by this script when it is executed?

我很想知道一个解决方案,将工作开箱即用,而不需要安装额外的软件包。这可能吗?

I would love to know a solution, which will work out of the box without a need of installing additional packages. Is it possible?

谢谢!

推荐答案

我从来没有做过这样的事情;)
这将编译一些C源代码,创建包含二进制(以及简单的开发原始脚本)在 b.bash 剧本

i never done something like this before ;) this will compile some c source, create a b.bash script containing the binary (and the original script for simple development)

(a.bash)

#!/bin/bash

if [ "$0" == "b.bash" ];then
  tail -n +$[ `grep -n '^BINARY' $0|cut -d ':' -f 1` + 1 ] $0 | base64 -d > a2.out
  chmod +x a2.out
  ./a2.out
  echo $?
  exit
fi

cat "$0" > b.bash
echo "BINARY" >> b.bash
cat > a.c << EOF
int     main(){
        return 12;
}
EOF
gcc a.c 
base64 a.out >> b.bash

与调用(a.bash产生b.bash):

invoke with (a.bash generates b.bash):

bash a.bash ;bash b.bash

我不知道如何规避二进制写出到一个临时文件执行前...

i don't know how to evade writing out the binary into a temporary file before execution...
