linux命令cd回退_cd命令退回目录的方法

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
