PWD(1) General Commands Manual PWD(1)
NAME
pwdreturn working directory name
SYNOPSIS
pwd
[-LP]
DESCRIPTION
pwd writes the absolute pathname of the current working directory to the standard output.
 
The following options are available:
-L
If the PWD environment variable is an absolute pathname that contains neither "/./" nor "/../" and references the current directory, then PWD is assumed to be the name of the current directory.
-P
Print the physical path to the current working directory, with symbolic links in the path resolved.
 
The default for the pwd command is -P.
 
pwd is usually provided as a shell builtin (which may have a different default).
EXIT STATUS
The pwd utility exits 0 on success, and >0 if an error occurs.
SEE ALSO
STANDARDS
The pwd utility is expected to be conforming to IEEE Std 1003.1 (“POSIX.1”), except that the default is -P not -L.
BUGS
In csh(1) the command dirs is always faster (although it can give a different answer in the rare case that the current directory or a containing directory was moved after the shell descended into it).
 
pwd -L relies on the file system having unique inode numbers. If this is not true (e.g., on FAT file systems) then pwd -L may fail to detect that PWD is incorrect.
