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
