ZSH thinks unterminated quote if preceded by exclamation mark (!)












1















I have zsh 5.3 (through oh-my-zsh), if I run echo --message="foo!", I get unterminated quote prompt on the next line:



$ echo --message="foo!"

dquote>


This doesn' happen in bash.



When I drop the ! character from the argument, it works fine:



$ echo --message="foo"

--message=foo


What’s happening here?




I should also note that if I answer the unterminated quote prompt with " and hit return, I get this output, which totally drops the !:



$ echo --message="foo!"

dquote> "

--message=foo





zsh

          That's the history expansion at work.



          This is what the zshexpn(1) manpage says about it:




          If the shell encounters the character sequence !" in the input, the
          history mechanism is temporarily disabled until the current list (see
          zshmisc(1)) is fully parsed. The !" is removed from the input, and
          any subsequent ! characters have no special significance.

          • So as either escape "foo!" or use single quotes 'foo!'. Or even "foo!"!", !" "foo!", etc..
