It is valid, though. See the POSIX specification: http://pubs.opengroup.org/onlinepubs/9699919799/utilities/V3_chap02.html#tag_18_02_03 ===begin quote=== 2.2.3 Double-Quotes [...] \ The <backslash> shall retain its special meaning as an escape character (see Escape Character (Backslash)) only when followed by one of the following characters when considered special: $ ` " \ <newline> ===end quote=== So, this should simply work. It worked on ash before. It also works on every other POSIX shell, and existing scripts rely on it. - M. _______________________________________________ busybox mailing list busybox@busybox.net http://lists.busybox.net/mailman/listinfo/busybox
