PWD(1)							    BSD General Commands Manual 						    PWD(1)

NAME
pwd -- return working directory name SYNOPSIS
pwd [-LP] DESCRIPTION
The pwd utility writes the absolute pathname of the current working directory to the standard output. Some shells may provide a builtin pwd command which is similar or identical to this utility. Consult the builtin(1) manual page. The options are as follows: -L Display the logical current working directory. -P Display the physical current working directory (all symbolic links resolved). If no options are specified, the -P option is assumed. ENVIRONMENT
Environment variables used by pwd: PWD Logical current working directory. DIAGNOSTICS
The pwd utility exits 0 on success, and >0 if an error occurs. STANDARDS
The pwd utility conforms to IEEE Std 1003.1-2001 (``POSIX.1''). SEE ALSO
builtin(1), cd(1), csh(1), sh(1), getcwd(3) BUGS
In csh(1) the command dirs is always faster because it is built into that shell. However, 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. The -L option does not work unless the PWD environment variable is exported by the shell. BSD
