A more extensive patch to allow "-e -n" or "-n -e" is left as an exercise for the reader. --- bin/sh/bltin/echo.c.orig Thu Jul 18 21:39:13 2002 +++ bin/sh/bltin/echo.c Thu Jul 18 21:40:22 2002 @@ -73,6 +73,12 @@ eflag++; #endif ap++; + } else if (equal(p, "-ne") || equal(p, "-en")) { +#ifndef eflag + eflag++; +#endif + nflag++; + ap++; } } while ((p = *ap++) != NULL) { >Release-Note: >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
