Wrong Exit Codes?

Wrong Exit Codes?

[Eskandar Ensafi]

Hello,

Is this a bug or a feature (I would call it a bug, unless there is an
option to turn this behavior off):

If the previous command causes an error, then typing "exit" will exit
zsh (2.6 beta14) with the previous command's non-zero exit code.

For example:

% zsh
% echo good_command
good_command
% exit
% echo $?  # Zero exit code as expected.
0
% zsh
% bad_command
zsh: command not found: bad_command
% exit
% echo $?  # Notice the non-zero exit code.  Doesn't "exit" = "exit 0" ?
1
% exit

This behavior is wrong, isn't it?

Thanks!

This is what the manual says it does.  It's also what the sh manual
says.  It seems to be standard behaviour.  Even the csh manual page
claims it does the same thing, except it actually doesn't (at least
not here).

  exit [ n ]
       Exit the shell with the exit code specified by n; if
       none is specified, use the exit code from the last
       command executed.  An EOF condition will also cause the
       shell to exit, unless the IGNOREEOF option is set.
