You can do that with precmd:

precmd() {
  local h=$[ $(print -P '%h') % 10 ]
  if [[ $h -eq 0 ]] then
    ...
  fi
}

Interestingly neither `if [[ $(print -P '%h') % 10 -eq 0 ]]', nor
`h=$(print -P '%h'); if [[ $h % 10 -eq 0]]' works, both give a parse
error.

Oops, I just found, that:

precmd() { [ ( $(print -P '%h') % 10 ) -eq 0 ] && ... }

works (with the `[...]' thing, but not with `[[...]]').

Bye
 Sven
