Thanks. Well, there is a missing space in the command:

> 2022-08-04T08:34:37.0618380Z 08:29:48.506172 tramp-send-command (6) # echo -n "">/var/folders/24/8k48jl6d249_n_qfxwsl6xvm0000gn/T/tramp-testB8ibE4

Would it work if the command is

--8<---------------cut here---------------start------------->8---
echo -n "" >/var/folders/24/8k48jl6d249_n_qfxwsl6xvm0000gn/T/tramp-testB8ibE4
--8<---------------cut here---------------end--------------->8---

If not, what else would be portable? Something like this?

--8<---------------cut here---------------start------------->8---
cat </dev/null >/var/folders/24/8k48jl6d249_n_qfxwsl6xvm0000gn/T/tramp-testB8ibE4
--8<---------------cut here---------------end--------------->8---

Best regards, Michael.
