How to use pushd and popd commands in Linux
Today, I will talk to you about how to use pushd and popd commands in Linux. Many people may not know much about it. In order to make you understand better, the editor has summarized the following contents for you. I hope you can get something according to this article.
Pushd
Press the directory into the directory stack and carry out the directory switching command
Usage:
Pushd [- n] [+ N |-N | dir]
Parameters:
+ n switch directories, the nth from right to left, whichever is the current directory
-n switch directories, according to the current directory, the nth from left to right
Example:
The code is as follows:
[root@localhost zhangy] # pushd / root
The symbol ~ / home/zhangy # represents the root home directory
The code is as follows:
[root@localhost zhangy] # pushd / home/zhangy/download/
/ home/zhangy/download / home/zhangy ~ # add directory
The code is as follows:
[root@localhost download] # pushd / usr/local/
/ usr/local / home/zhangy/download / home/zhangy ~ # add directory
The code is as follows:
[root@localhost download] # pushd + 1
/ home/zhangy ~ / usr/local / home/zhangy/download
The code is as follows:
[root@localhost zhangy] # # switched to the original directory
The code is as follows:
[root@localhost zhangy] # pushd + 1
~ / usr/local / home/zhangy/download / home/zhangy
The code is as follows:
[root@localhost ~] # # change to home directory
The code is as follows:
[root@localhost ~] # pushd-2
/ usr/local / home/zhangy/download / home/zhangy ~
The code is as follows:
[root@localhost local] # # switched to the / usr/local directory
Popd
Pop the directory off the directory stack
Usage:
Popd [- n] [+ N |-N | dir]
Parameters:
+ n Delete the directory added by pushd, counting from left to right, depending on the current directory, delete the nth.
-n delete the directory added by pushd, and delete the nth from right to left, whichever is the current directory.
Example:
The code is as follows:
[root@localhost dev] # pushd / usr/
/ usr / dev / home/zhangy
The code is as follows:
[root@localhost usr] # popd + 1 # deleted / dev
/ usr / home/zhangy
The code is as follows:
[root@localhost usr] # pushd / home/
/ home/ usr / home/zhangy
The code is as follows:
[root@localhost home] # popd-1 # deleted / usr
/ home/ home/zhangy
