Unless you've read the >source you shouldn't even know that you can use "\<newline>" to continue >a long entry onto the next line! ;-) [[ There is one hint in an >example. ]] Mmm... the hosts_access(5) man page I've got in front of me (for V7.6) says Each access control file consists of zero or more lines of text. These lines are processed in order of appearance. The search terminates when a match is found. o A newline character is ignored when it is preceded by a backslash character. This permits you to break up long lines so that they are easier to edit. It then goes on to say o Blank lines or lines that begin with a `#' character are ignored. This permits you to insert comments and whitespace so that the tables are easier to read. If read carefully, that does make it clear that continuation lines are re-joined *before* checking for comments. In reality, I suspect many people will look down the list for the case they are interested in, and not look at "irrelevant" items, missing the highly significant interaction. Like so many UNIX man pages, it means precisely what it says, not what other experience may lead people to expect/assume/take for granted. :-( John Line -- John Line - Cambridge University Computing Service, Computer Laboratory, New Museums Site, Pembroke Street, Cambridge CB2 3QG, England.
