It is valid for the variable to be unset. +Parameter substitutions in the form ${param//#%search/replace} match +against "search" anchored at both ends of the parameter value. Previously +this syntax would have matched against "%search", anchored only at the head +of the value. The form ${param//#$search/replace} where the value +$search starts with "%" considers the "%" to be part of the search +string as before. + The MULTIBYTE option is on by default where it is available; this causes many operations to recognise characters as in the current locale. Older versions of the shell always assumed a character was one byte. |
