1. 编译 tarlz 的脚本

workdir=$(cd $(dirname ${0}) ; pwd)

yum install -y wget
wget http://download.savannah.gnu.org/releases/lzip/lzlib/lzlib-1.13.tar.gz
wget http://download.savannah.gnu.org/releases/lzip/tarlz/tarlz-0.23.tar.lz

yum install -y gcc-c++

# 编译 lzlib
cd ${workdir}
tar xzf lzlib-1.13.tar.gz && cd lzlib-1.13 && ./configure && make

# 编译 tarlz
cd ${workdir}
./lzlib-1.13/minilzip -d tarlz-0.23.tar.lz && tar xf tarlz-0.23.tar
cd tarlz-0.23 && ./configure CXXFLAGS+="-I ../lzlib-1.13" LDFLAGS="-L ../lzlib-1.13" && make

脚本执行完成后，则会在 tarlz-0.23 目录中生成 tarlz 文件。

2. tarlz 的使用方法

例如把目录 trand 打包并且压缩的命令如下

tarlz -c -9 -f trand.tar.lz trand/

对于文本文件，压缩率可以到 3% 左右。
