foreach

foreach name ( wordlist )
     commands
end

Assign variable name to each value in wordlist , and execute commands between foreach and end . You can use foreach as a multiline command issued at the C shell prompt (first Example), or you can use it in a shell script (second Example).

Examples

Rename all files that begin with a capital letter:

% foreach i ([A-Z]*)


? mv $i $i.new


? end

Check whether each command-line argument is an option or not:

foreach arg ($argv)
   # does it begin with - ?
   if ("$arg" =~ -*) then
      echo "Argument is an option"
   else
      echo "Argument is a filename"
   endif
end
