pwd —
return working directory
name
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 -L option
is assumed.
Environment variables used by pwd:
PWD
- Logical current working directory.
The pwd utility exits 0 on success,
and >0 if an error occurs.
Show current working directory with symbolic links resolved:
$ /bin/pwd
/usr/src/sys/kern
Show the logical current directory. Then use
file(1) to inspect the /sys
directory:
$ /bin/pwd -L
/sys/kern
$ file /sys
/sys: symbolic link to usr/src/sys
The pwd utility conforms to
IEEE Std 1003.1-2001 (“POSIX.1”).
The pwd command appeared in
Version 5 AT&T UNIX.
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.
