I have been caught several times by what appears to be a bug in vi. The problem shows up when I am using vi to edit a temporary file such as you get after invoking vi with the ~v command from mail. When I try to exit from vi with the ZZ command, I get the message "file exists; use w! to overwrite". I have no idea what causes this to happen and I am wondering if anyone else has noticed this. It happens about 10% of the times I use the ~v command. It may possibly have some connection with doing a :r command, at sometime in the edit, to include the contents of another file.

I too have experienced the ~v "use w! to override" problem in vi. It is caused by the :r command, but I've never taken the time to look into it. - sam praul ...decvax!ittvax!shp

I have a file whose contents is: 12345 67890 The cursor is on the 1, and I type the following sequence of commands: ma f5 y`a <cr> P Now, I think the P should insert 12345 before the 6 on the second line. Instead, it DELETES the 6789!! (Try it.) Am I wrong, or is this a bug? Steven Holtsberg (sdcrdcf!steve@UUCP, ucla-cs!holts@UUCP)
