I think it is more common for a '\' at the end of line to escape the usual meaning of the newline and have it interpreted as white space, but I don't know if fstab is parsed that way. Usually the convention only matters if you are going to mail the content or send it through other mechanisms that likely to reformat it. But, there is a more basic problem if the editor used to make this change doesn't wrap to the next screen line so you can edit without introducing a newline into the content. I thought they've all done that for decades. -- Les Mikesell lesmikes...@gmail.com ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

No, it looks like mount does not recognise the '\' character as an escape character. Thanks for all the replies to my question. I'll just have to put things all on one line.

Maybe mount needs coding to recognise some sort of escape character, similar to the way bash does?
