+.Sh NAME
+.Nm pwd
+.Nd return working directory name
+.Sh SYNOPSIS
+.Nm pwd
+.Sh DESCRIPTION
+.Nm Pwd
+writes the absolute pathname of the current working directory to
+the standard output.
+.Pp
+The pwd utility exits 0 on success, and >0 if an error occurs.
+.Sh STANDARDS
+The
+.Nm pwd
+command is expected to be
+.St -p1003.2
+compatible .
+.Sh SEE ALSO
+.Xr cd 1 ,
+.Xr csh 1 ,
+.Xr getwd 3
+.Sh BUGS
+In
+.Xr csh  1
+the command
+.Ic 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).
