First, if the error message is "should be in an empty directory", then why is a empty 2nd argument part of that test? That should probably be a separate test and separate error message.
I would test for empty directory like: set files * .* if test (count $files) != 0; echo error; end And to test for empty parameters, use `set -q` if not set -q argv[2]; echo "argv[2] is empty"; end On Tue, Mar 5, 2019 at 8:59 AM Tassilo Horn <t...@gnu.org> wrote: > Hi all, > > in a script, I have this code: > > --8<---------------cut here---------------start------------->8--- > if test \( (count (ls -A .)) != "0" \) -a \( -z $argv[2] \) > echo "This should be run in an empty directory." > exit 3 > end > --8<---------------cut here---------------end--------------->8--- > > It errors with: > > test: Expected a combining operator like '-a' at index 4 > > I don't see what's wrong here.
