Geting Start:

• Create shell script like:userHabitInit.sh
  $vim ~/userHabitInit.sh
• Input all these code below, you can add another alias if you need.

    #!/bin/bash

    #Set a name and path of a new user habit shell script.
    habitShell=xxx/userHabit.sh

    #Set user habit.
    userHabit='
    alias tc="cd xx"
    alias lib="cd xxx"
    alias catout="tail -f xxx"
    alias lany="ls -la xx*xx*"
    tomcatBin=xxxx
    function tomcatRestart {
        ${tomcatBin}/shutdown.sh
        ${tomcatBin}/catalina.sh jpda start
    }
    alias catrs="tomcatRestart"
    '

    #Set a nick name for starting this user habit configuration.
    nickName="habit"

    #Game start:
    if [ -a ${habitShell} ];then
        echo "[Warning]:"
        echo "${habitShell} exist!"
        echo "Please check it or remove it first, and then retry."
        echo "Exit..."
    else
        #touch xxxx/habitShell.sh
        touch ${habitShell}

        #Create some new 'alias' or something useful user habits.
        echo "#!/bin/bash\n${userHabit}" >> ${habitShell}

        #Make these order effective permanently in each user account(root & zxin10).
        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
        chown xxx  xxx/userHabit.sh

        source ~/.bashrc
    fi

• 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.
