方法1、利用..(数字)来选择退回几集目录
例子1、:# cd /tmp/very/long/directory/structure/that/is/too/deep
        # ..4
        [Note: use ..4 to go up 4 directory level]
        # pwd
        /tmp/very/long/directory/structure/

方法2、利用..和...来回退,..表示退回上级目录,每多加一个.    就是多往上回退一级目录
例子2、alias ...="cd ../.."
            alias ....="cd ../../.."
            alias .....="cd ../../../.."
            alias ......="cd ../../../../.."
            # cd /tmp/very/long/directory/structure/that/is/too/deep
            # .....
            [Note: use ..... (five dots) to go up 4 directory level]
            # pwd
               /tmp/very/long/directory/structure/


方法3、和方法2类似
例子3、alias cd..="cd .."
alias cd...="cd ../.."
alias cd....="cd ../../.."
alias cd.....="cd ../../../.."
alias cd......="cd ../../../../.."
# cd /tmp/very/long/directory/structure/that/is/too/deep
# cd.....
[Note: use cd..... to go up 4 directory level]
# pwd
/tmp/very/long/directory/structure
