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 `[[...]]').

# of commands, not PERIODIC

[Uncle Tim]

I know of the periodic command, which works based on a set-time.
I'd like some command which will be run based on the number of
commands which are entered into the history list.  I'd like to have
something run every 10 lines or so...
