〖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;

tarfile=package_content_$$.tgz
wrapfile=wrap_$$.sh

echo -e "start packing ..\n"
tar zcvf $tarfile $files $install_script
generate_wrapper_script $install_script $wrapfile
cat $wrapfile $tarfile > $package_name
chmod +x $package_name

echo -e "\noutput: $package_name\n"

rm -f $tarfile
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
