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?

Answer 1

There should be no in :

foreach file ( . )

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

Answer 2

I found that csh was giving me issues splitting the files into their own iteration of $file (it would lump all the files into a single string with EOL's in between. Go figure..,), so I had to use the following explicit call to ls :

foreach file ( `ls /path/to/directory/` )
    echo "/path/to/directory/$file"
end
