ctrl+d is the most dangerous kind! Since that one can also exit the terminal itself.

gdb takes, depending on the situation, one time ctrl+d or two times ctrl+d to quit. It's a trap!

So since gdb usually takes two times, muscle memory learns two times, but then in that rare instance where it required it only once... logged out of ssh :(

In bash: IGNOREEOF=10

In zsh: setopt ignore_eof

In ksh: set +o ignoreeof

In tcsh/csh: set ignoreeof

Normally I just do this for login shells, so I can quickly exit out of subshells.

Similarly, to not overwrite an existing file when doing output redirection, there is bash's noclobber option.

10 ???

For bash I set `IGNOREEOF=1` so as to have to press ctrl+d twice to exit. Ten times seems a bit too many.

How to do the same for zsh?
