    `cd [\pathname]'
If a pathname specified, change to that directory. Normal unix filenames are used, as in the C-shell convention. For example, the commands ``cd ~/src`' and ``cd $HOME/src`' are equivalent. You may specify relative pathnames as in ``cd ../sister_directory`'. If no \pathname directory path is specified, go to the home directory, exactly as ``cd ~`' and ``cd $HOME`' do.
