Learn Linux every 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 thelinkpath.

4. Common examples:

Example 1: Viewing the full path of the default working directory with the PWD command

Command:

Pwd

Output:

[Email protected] ~]# pwd

/root

[Email protected] ~]#

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

Command:

Pwd

Output:

[Email protected] ~]# cd/opt/soft/

[Email protected] soft]# pwd

/opt/soft

[Email protected] 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:

[Email protected] soft]# CD/ETC/INIT.D

[Email protected] init.d]# pwd

/etc/init.d

[Email protected] init.d]# pwd-p

/etc/rc.d/init.d

[Email protected] init.d]#

Example 4:/bin/pwd

Command:

/bin/pwd [ options ]

Options:

-L directory connection link, output connection path

-P Output Physical path

Output:

[Email protected] init.d]#/bin/pwd

/etc/rc.d/init.d

[Email protected] init.d]#/bin/pwd--help

[Email protected] init.d]#/bin/pwd-p

/etc/rc.d/init.d

[Email protected] init.d]#/bin/pwd-l

/etc/init.d

[Email protected] init.d]#

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

Output:

[Email protected] init.d]# Cd/opt/soft

[Email protected] soft]# mkdir removed

[Email protected] soft]# CD removed/

[Email protected] removed]# pwd

/opt/soft/removed

[Email protected] removed]# RM. /removed-rf

[Email protected] removed]# pwd

/opt/soft/removed

[Email protected] removed]#/bin/pwd

/bin/pwd:couldn ' t find directory entry in ' . " With matchingi-node

[[Email protected] removed]# CD

[Email protected] ~]# pwd

/root

[Email protected] ~]#
