pwd
pwd displays the absolute path name of the working directory to standard output.
If the current working directory is a symbolic link to another directory, the path name displayed depends on the setting of the shell's logical flag. See set for more information.
pwd is a built-in shell command and is also a separate utility.
See Localization for more information.
