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] ~]#
