〖Linux〗简单的将Shell和一些文件打包成一个单独的“可执行文件”

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；

rm -f $wrapfile

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
