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；

generate_wrapper_script(){
 local install_script=$1
 local wrapper_script=$2
 cat <<-'EOT' >$wrapper_script
#!/bin/sh
echo "begin ..."
unpackdir=/tmp/$(basename $0)_unpack
rm -rf $unpackdir 2>/dev/null
mkdir -p $unpackdir
echo "unpacking ..."
sed '1, /^#__SCRIPTEND__/d' $0 | tar zxf - -C $unpackdir
if [ $? -ne 0 ]; then
 echo "unpack package failed."
 exit 1
fi

cd $unpackdir

}

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
