That's correct. In shell glob pattern bracket expressions, the standard negator is '!' and not '^'. Many shells support '^' as a synonym, but that's an extension to the standard and not mandatory. Dash usually doesn't support such extensions. But all shells support '!', so just that instead and you're safe. Reference: http://pubs.opengroup.org/onlinepubs/9699919799/utilities/V3_chap02.html#tag_18_13 "If an open bracket introduces a bracket expression as in XBD RE Bracket Expression, except that the <exclamation-mark> character ( '!' ) shall replace the <circumflex> character ( '^' ) in its role in a non-matching list in the regular expression notation, it shall introduce a pattern bracket expression." - M. -- To unsubscribe from this list: send the line "unsubscribe dash" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
