I don't think changing yesno would be appropriate in this case. What if the string is "n\by"? What if \b is not the erase character? What if the string is "yes" and `e' is the `erase' character? Should it handle both DEL and ERASE characters? Should it also handle word-erase and line-erase characters? I know you said `normally used...', so I assume you wanted something simple, befitting yesno's status, but I don't see an appropriate way to solve the problem by changing yesno. Alternative opinions (or patches to yesno.c) welcome. _______________________________________________ Bug-coreutils mailing list Bug-coreutils@gnu.org http://lists.gnu.org/mailman/listinfo/bug-coreutils
