Hi,
When opening my fixed xterm's from my desktop startup file I'd like them
to not quit when accidentaly pressing CTRL-D.
How can I pass zsh's ignoreeof to the xterm?
(I don't want that option in my .zshrc as I like to terminate temporary
xterm's with CTRL-D)
I tried "xterm -e zsh -i -7" which works but wondering if there is
another way?
Thanks,

another way (linux'izm):
[[ $(< /proc/$PPID/comm) == "xterm" ]] && setopt ignoreeof
to .zshrc

What speaks against using the line above in your desktop startup file?
Especially as you require to have behavior A for 'startup xterms' and
behavior B for 'temporary xterms' -- how is the shell expected to
distinguish the one from the other¹?

¹ Of course you could create a symlink 'startup-xterm' linking to xterm,
and then differentiate in .zshrc between xterm and startup-xterm. But
when allowing such overhead, you could equally well create a wrapper
script or something alike.

Just wondering if "-e zsh -i" gets me exactly the same shell and
environment (except ignoreeof) as if no "-e" was passed?

Interesting approach.

Sorry, I thought you wanted to avoid CTRL-D to kill *any*
terminal.
The session leader is typically the process that is invoked by
the terminal emulator.
(( $(ps -o sid= -p $$) == $$ ))
returns true for the zsh started by xterm, but not for other
zshs started in that xterm in other processes.
Note (in case that has not already been said) that you can start
xterm as:
xterm -e zsh -o ignoreeof

Hi,
apparently (( $(ps -o sid= -p $$) == $$ )) is always true, either when
launching xterms from ~/.xession (those I want ignoreeof) or later
through an openbox key mapping (not ignoreeof).
What do you mean by session leader?

You could set ignoreeof only when zsh is a session leader:
In ~/.zshrc:
(( $(ps -o sid= -p $$) == $$ )) && setopt ignoreeof
