       pwd - Return the absolute path of the current working directory


       Returns the absolute path name of the current working directory.

       Sometimes  it  is useful to change to a known directory when running some external command
       using exec, but it is important to keep the application usually running in  the	directory
       that  it  was  started  in (unless the user specifies otherwise) since that minimizes user
       confusion. The way to do this is to save the current directory while the external  command
       is being run:
	      set tarFile [file normalize somefile.tar]
	      set savedDir [pwd]
	      cd /tmp
	      exec tar -xf $tarFile
	      cd $savedDir

       file(n), cd(n), glob(n), filename(n)

       working directory
