有时候给别人分享一个工具的时候,同时需要提供的文件比较多;
如果分享一个压缩包还得教会对方如何解压、执行哪个脚本,感觉需要传输的内容多了就不方便;
把几个Shell脚本和文件打包成一个“单独的可执行文件”,对方接收到这个文件,只需要执行一下这个文件,就可以实现解压、执行对应脚本了,相对比较方便;

文件内容保存到 shell_pack.sh,使用方法举例:
./shell_pack.sh -p logcat_install -s logcat_install.sh logcat_all.sh logcat_wrapper.sh vmstat2
将产生可执行文件“logcat_install”,执行logcat_install时,会解压自身文件内的tar.gz文件,并执行关键的脚本 logcat_install.sh
