Linux Basics Command (3) PWD command

Linux uses the PWD command to view the full path of the current working directory. Simply put, every time you operate on a terminal, you have a current working directory.

When you are unsure of the current position, you use PWD to determine the exact location of the current directory within the file system.

1. Command format:

PWD [Options]

2. Command function:

View the full path to the current working directory

3. Common parameters:

Usually without any arguments

If the directory is a link:

Format: Pwd-p shows the actual path rather than using the connection path.

4. Common examples:

Example 1: View the full path to the default working directory with the PWD command

Command:

Pwd

Output:

[Root@localhost ~]# pwd

/root

[Root@localhost ~] #

Example 2: Use the PWD command to view the specified folder

Command:

Pwd

Output:

[Root@localhost ~]# cd/opt/soft/

[Root@localhost soft]# pwd

/opt/soft

[Root@localhost soft]#

Example three: When a directory connection link, Pwd-p displays the actual path instead of using the connection path; pwd shows the connection path

Command:

Pwd-p

Output:

[Root@localhost soft]# CD/ETC/INIT.D

[Root@localhost init.d]# pwd

/etc/init.d

[Root@localhost init.d]# Pwd-p

/etc/rc.d/init.d

[Root@localhost init.d]#

Instance 4:/bin/pwd

Command:

/bin/pwd [Options]

Options:

-L directory connection link, output connection path

-P Output Physical path

Output:

[Root@localhost init.d]#/bin/pwd

/etc/rc.d/init.d

[Root@localhost init.d]#/bin/pwd--help

[Root@localhost init.d]#/bin/pwd-p

/etc/rc.d/init.d

[Root@localhost init.d]#/bin/pwd-l

/etc/init.d

[Root@localhost init.d]#

Instance five: The current directory is deleted, and the PWD command still displays that directory

Output:

[Root@localhost init.d]# Cd/opt/soft

[Root@localhost soft]# mkdir removed

[Root@localhost soft]# CD removed/

[Root@localhost removed]# pwd

/opt/soft/removed

[Root@localhost removed]# rm.. /removed-rf

[Root@localhost removed]# pwd

/opt/soft/removed

[Root@localhost removed]#/bin/pwd

/bin/pwd:couldn ' t find directory entry in "..." with matching I-node

[Root@localhost removed]# CD

[Root@localhost ~]# pwd

/root

[Root@localhost ~]#
