This article introduces the knowledge of "how to use linux to switch directories with commands". In the operation of actual cases, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

1.cd-the function is to quickly switch to the previous directory, as follows:

The code is as follows:

Amosli@amosli-pc:~$ cd learn/fd/

Amosli@amosli-pc:~/learn/fd$ cd-

/ home/amosli

2.dirs: displays the directory stack, listing the directories saved in the current stack

The code is as follows:

Amosli@amosli-pc:~/learn/fd$ dirs

~ / learn/fd

Description: the-p parameter of dirs can display the list of directories in the stack in the form of one directory per line.

The-v parameter can be numbered before the directory

Note: when there is-v, you can display it in the form of a directory per line without adding-p.

The code is as follows:

Amosli@amosli-pc:~/learn/fd$ dirs-p-v

0 ~ / learn/fd

The directory on the stack is at the top

3. Introduction to the pushdpopd command

Pushd: switch to the directory as a parameter and push the original directory and the current directory into a virtual stack

If you do not specify a parameter, it goes back to the previous directory and swaps the two nearest directories in the stack

Popd: removes the most recent directory in the stack

The code is as follows:

Amosli@amosli-pc:/$ pushd bin/

/ bin /

Amosli@amosli-pc:/bin$ pushd / home/amosli/learn/fd/

~ / learn/fd / bin /

Amosli@amosli-pc:~/learn/fd$ dirs-p-v

~ / learn/fd

/ bin

/

Amosli@amosli-pc:~/learn/fd$ pushd / home/amosli/develop/

~ / develop ~ / learn/fd / bin /

Amosli@amosli-pc:~/develop$ dirs-p-v

~ / develop

~ / learn/fd

/ bin

/

The above uses the pushd command to push /, bin/, / home/amosli/learn/fd/, / home/amosli/develop/ onto the stack, which is a last-in, first-out (LIFO,last in first out) data structure.

So how do I change directories?

1) if it is a direct pushd with no parameters, you can switch to the nearest directory directly.

The code is as follows:

Amosli@amosli-pc:~/develop$ pushd

~ / learn/fd ~ / develop / bin /

Amosli@amosli-pc:~/learn/fd$

2) pushd + n

You can also follow the number and switch directly to the appropriate directory. For example, switch to / (root directory) as follows:

The code is as follows:

[code]

Amosli@amosli-pc:~/learn/fd$ pushd + 3

/ ~ / learn/fd ~ / develop / bin

Amosli@amosli-pc:/$ ls

How do I remove a directory?

1) popd directly removes the most recent directory

The code is as follows:

Amosli@amosli-pc:/$ dirs-p-v

0 /

1 ~ / learn/fd

2 ~ / develop

3 / bin

Amosli@amosli-pc:/$ popd

~ / learn/fd ~ / develop / bin

Amosli@amosli-pc:~/learn/fd$ dirs-p-v

0 ~ / learn/fd

1 ~ / develop

2 / bin

2) popd + n

Directly follow the number to remove the specified directory

The code is as follows:

Amosli@amosli-pc:~/learn/fd$ popd + 1

~ / learn/fd / bin

Amosli@amosli-pc:~/learn/fd$ dirs-p-v

0 ~ / learn/fd

1 / bin
