Could you provide more context? If you are trying to use ‘seq-empty-p’
with the result of ‘read-number’: that does not work because the result
of ‘read-number’ is a number not a sequence (which a string as returned
by ‘read-from-minibuffer’ is).



Right, this is what I have



      (cmd-cnum (read-number "context: " 8))

      (cmd-temp `("grep" "-hir" ,cmd-excl ,cmd-incl
              "-C" ,cmd-cnum ,cmd-ptrn))
      
      (cmd (concat (mapconcat #'shell-quote-argument cmd-temp " ")
            " " cmd-path)) )
