pwd
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.
