One Linux command per day (3): pwd command

In Linux, use the PWD command to view the full path to the current working directory. Simply put, you will have a current working directory every time you operate in a terminal.

When unsure of the current location, PWD is used 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:

Normally without any parameters

If the directory is a link:

Format: Pwd-p shows the actual path, not the link path.

4. Common examples:

Example 1: Viewing the full path of 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 is linked, Pwd-p displays the actual path, not 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]#

Example 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 ~]#
