In C shell How do I get the folder name using a foreach loop

foreach directory (`ls`)
test -d "$directory" && echo "This is a directory: $directory"
end

This is what I had before:

#! /bin/csh -f
set SourceDir = /home/milligram/mnt
set DestDir_IOS = Myvideos/IOS


foreach directory ($SourceDir)

echo $SourceDir

end


can you corect it for me. Thanks a million!!!!!!!!!

Can you explain

what is the 'ls' for?
 what does the "test" do? is it a cshell syntax?
Can variables be placed in quotes.."$directory"


foreach directory (`ls`)
test -d "$directory" && echo "This is a directory: $directory"
end
