   echo "Running .cshrc ..."
   set path = ( $path /local/bin ~/bin )   # Search for my commands

   alias cd            'cd \!*;echo $cwd'
   alias cp            'cp -i'
   alias copy          'cp -i'
   alias mv            'mv -i'
   alias ren           'mv -i'
   alias rm            'rm -i'
   alias del           'rm -i'
   alias where         'echo $cwd'

# Skipping remaining script if this is not an interactive shell
   if ( $?USER == 0 || $?prompt == 0 ) exit

# Settings for interactive shells
   set history = 40  # Saving the last 40 commands in a buffer
   set histsave = 40 # Saving the last 40 commands in .history
   set ignoreeof     # Do not log me out if I hit ^D (EOF key)
   set filec         # Provide me filename completion when hit ESC
   set noclober      # Don't overwrite an existing file

   alias type        more
