Detailed explanation of pwd commands in CentOS

Pwd (Print Working Directory)

Name: pwd-print name ofcurrent/working directory enter the current working path

Syntax: pwd [option]

Parameter: -- help -- version

Instance:

1) display the current working path

[Root @ localhost ~] # Pwd

/Root

2) display the actual directory of the soft connection, rather than the directory of the soft connection. Parameter-P

[Root @ localhostnetwork-scripts] # cd/etc/init. d

Root@localhostinit.d # pwd

/Etc/init. d

[Root@localhostinit.d] # pwd-P

/Etc/rc. d/init. d

3) The pwd error shows the deleted directory.

[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 ~] #

---------------------------- Subsequent self-Summary ----------------------------------

The pwd command should also be less functional, that is, to check where our current directory is and where the real-P directory is.
