Put a leading space before the command.

That depends on the HIST_IGNORE_SPACE option, which isn't set by default.

After setting the HIST_IGNORE_SPACE option, you can also define aliases
that represent commands that won't ever get stored in the history:
just define the alias expansion with a leading space.

For example, if you never want a "cd" command to appear in the history,
do this:

    setopt HIST_IGNORE_SPACE
    alias cd=' builtin cd'

I cannot do that. That command is

cd "`echo '\0057...'`"

and it's being called from Midnight Commander when switching panels.

This is exactly the same question you asked back on July 11th, and the
answer hasn't changed:

Wayne just told you exactly the same thing:

Using the setopt and the alias -should- work with Midnight Commander.

Yes, it works and removes _all_ 'cd' commands. I want to remove only
these, which match pattern 'cd "`echo .*`"'.
So removing from history is possible only by leading space, not by
configurable pattern, is it right? :/

    why don't you start midc in a separate zsh instance with tweaked
    settings?

That is correct.  There was some discussion several months ago of having
a pattern match for history exclusion, but it didn't lead to anything.

It is, however, possible to selectively insert into the history commands
that would otherwise be ignored.  Try something like this:

  setopt hist_ignore_space
  alias cd=' builtin cd'
  function preexec {
    if [[ "$1" = 'cd '* && "$1" != 'cd "`echo '*'`"' ]]
    then
      print -s "$1"	# explicitly add it to the history
    # else it already will be in the history, so do nothing
    fi
  }

} (without space!) mc calls ' cd `echo "..."`' - it ommits 'builtin'
} keyword, so the command is leaded by space

That's very interesting.  It's not, as far as I can tell, a documented
behavior of Midnight Commander, so it's probably an accident.

I don't know if this thread is worthy of a zsh FAQ entry or not.  If it
is, it's probably worth mentioning that the MC_CONTROL_FILE environment
variable can be a clue that your rc files need to do different setup
(e.g., I wouldn't recommend using themed prompts within mc).  However,
it's only a clue, because not all compilations of mc export that, and
there doesn't appear to be anything mc consistently does to identify
itself to the subservient shell.

   Else I get blank lines in history which I don't wont.How can I get
