One Linux command per day (3): pwd command

Transferred from: http://www.cnblogs.com/peida/archive/2012/10/24/2737730.html

In Linux, use the PWD command to view the full path to the current working directory. To put it simply, 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 []

2. Command function:

View the full path to the current working directory.

3. Common parameters:

In general, no parameters are taken.

If the directory is a link:

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

4. Common examples: Instance 1: View the full path of the default working directory with the PWD command

Command: PWD

Output:

1 pwd 2 /root3 [[email protected] ~]#

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

Command: PWD

Output:

1 [[email protected] ~]# cd/opt/soft/2pwd3 /opt/soft4 [[email] Protected] soft]#

Example 3: 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:

1 [[email protected] soft]# cd/etc/2pwd3 /etc/init.d4  pwd -P5 /etc/rc.d/init.d6 [[email protected] init.d]#

Example 4:/bin/pwd

Command:/bin/pwd [options]

Option:-L directory connection link, output connection path

-P Output Physical path

Output:

1 [[email protected] init.d]#/bin/pwd2 /etc/rc.d/init.d3 [[email] Protected] init.d]#/bin/pwd --help4 [[email protected] init.d]#/bin/pwd -P  5 /etc/rc.d/init.d6 [[email protected] init.d]#/bin/pwd -L  7 /etc/init.d8 [[email protected] init.d]#

Example 5: The current directory is deleted, and the PWD command still displays that directory

Output:

1[Email protected] init.d]# cd/opt/Soft2[Email protected] soft]#mkdirremoved3[Email protected] soft]# CD removed/4[Email protected] removed]#pwd5/opt/soft/removed6[Email protected] removed]#RM.. /removed-RF7[Email protected] removed]#pwd8/opt/soft/removed9[Email protected] removed]#/bin/pwdTen/bin/pwd: couldn't Find directory entry in ":" with matching I-node One [[Email protected] removed]# CD A[Email protected] ~]#pwd -/Root -[Email protected] ~]#
