        echo "alias ${nickName}=\"source ${habitShell}\"" >> ~/.bashrc
        echo "alias ${nickName}=\"source ${habitShell}\"" >> /home/zxin10/.bashrc

        #Change the owner of 'userHabit.sh' script.
        chmod 770 xxx/userHabit.sh

        source ~/.bashrc

• upload this shell script and:
  $chmod 770 ~/userHabitInit.sh

• Init :
  $source ~/userHabitInit.sh

• Use $habit command to load all alias settings.

Problems :

Line break is not the same between Windows and Unix, it is \r\n in Windows though \n in Unix. If don't convert the problem will called this error:
/bin/bash^M: bad interpreter: No such file or directory?

Solution:

• $vim userHabitInit.sh
• Use :set ff=unix to convert the file to Unix format
• Then use source ~/userHabitInit.sh to load all settings.
