How to compare integers on fish shell?

Question

There isn't much documentation on fish. I need to know if

    date '+%k' is greater than 8

How do I do it? Thanks.

Answer 1

You can use the test fish builtin, like:

if test (date +%k) -gt 8
   ...
end

Answer 2

test or [ are the way you would do this. This is true of all shells, since these are external commands.

if [ (date '+%k') -ge 8 ]
    echo "It's larger!"
end
