foreach syntax in csh

Question

For this csh script

#!/bin/csh

foreach file in (.)
  echo "$file"
end

I get this error

foreach: Words not parenthesized.

How can I fix that?

Solution

There should be no in:

foreach file ( . )

Be sure to read Stop Using (and Teaching) C-Shell.

FYI, some people may be forced to use CSH due to vendor hardware - as in the case of ASML equipment, for example. ( wiki.nanotech.ucsb.edu/wiki/Stepper_3_(ASML_DUV) ) Installing new shells (or installing anything in general) is not recommended on such equipment to ensure functionality is not compromised. I do entirely agree though - I wish I could use something other than CSH!
