Name

foreach

Synopsis

                     
                        name(wordlist)commands
                     
                  

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 (see the first of the following examples), or you can use it in a shell script (see the 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
