'foreach' command

  The following is an excerpt form the NetBSD guide -

    "Chapter 27 Obtaining the sources"

    You now must extract them all to /:
    % foreach file (*.tgz)
    ? tar -xzf $file -C /
    ? end

  What must I install from ports to have 'foreach' program
in my $PATH?

  I installed 'tcl' but still no good. My OS is NetBSD-3.1.

  Thanks, TM

GW:/home/bqt> which foreach
foreach: shell built-in command.
