一，安裝 dsh

切換到root用戶，然后切換到work_home_yourname

wget? http://www.netfort.gr.jp/~dancer/software/downloads/libdshconfig-0.20.9.tar.gz
tar zxvf libdshconfig-0.20.9.tar.gz
cd libdshconfig-0.20.9
./configure

出錯記得修復（ Ubuntu: configure error: C++ preprocessor "/lib/cpp" fails sanity check??

?apt-get install???build-essential）

make && make install
?
wget? http://www.netfort.gr.jp/~dancer/software/downloads/dsh-0.25.9.tar.gz
tar zxvf dsh-0.25.9.tar.gz
cd dsh-0.25.9
./configure
make && make install
?
ln -s /usr/local/lib/libdshconfig.so.1 /lib/

echo "/usr/local/lib/libdshconfig.so.1">> /etc/ld.so.conf

ldconfig

[root@localhost ~]# which dsh
/usr/local/bin/dsh
?

二，用法介紹：
