The output with grep-2.5.3 is 3:4, which means that the string "4" was found at offset 3 (0-based). With grep-2.5.1, you get 0:4, which means that the line containing the string "4" has offset 0. The "tr" commands in the script ensure that the patterns we are looking for are always at the start of a line, so that it doesn't matter which version of grep is installed. -- Dick -- To unsubscribe from this list: send the line "unsubscribe linux-kbuild" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
