1.创建别名

$ alias dms='cd Oracle/Middleware/user_projects/domains/7001_costctl/'
$ dms
$ dms
$ pwd
/home/weblogic/Oracle/Middleware/user_projects/domains/7001_costctl

创建别名只是暂时的,一旦关闭终端设置的别名就失效了,要永久有效得写到~/.bashrc

 # echo "alias dms='cd Oracle/Middleware/user_projects/domains/7001_costctl/'" >> ~/.bashrc 
# source ~/.bashrc

2.取消别名

$ unalias dms

3.利用\将别名进行转义

 $ alias vi='vim'
$ vi startWebLogic.sh
