This is weird. As in, *deeply* weird.
I ssh as root from one box to another (there are keys involved), and I go
to vi a file, such as
# line 1 #
# line 2 #
# line 3
# line 4
And what I see in vi is
# line 3
# line 4
BUT, if I scroll the cursor over each line with the arrow key... I see all
four lines. I've also looked at another file, and same thing. Just checked
it out on the server I ssh'd in from, and no problem. And now, I just
ssh'd in from another windows, same way... and the weirdness isn't
there.
Anyone have any clues as to what's going on with that one session?

Unfortunately you are giving almost no details - OSs (original and target machine), shells, terminal settings, etc., so it's hard to do more than jump to potentially rash conclusions.

I ssh (with the key) from FrraBSD 9.3 box (from either /bin/sh Bourne shell or /usr/local/bin/bash Bourne again shell) to centos 5 (fully updated, bash shell), and my vi does behave as expected, it is: which vi /bin/vi vi -V ~ ~ VIM - Vi IMproved ~ ~ version 7.0.237 ~ by Bram Moolenaar et al. ~ Vim is open source and freely distributable I guess we need more detail about what you have. Here is the file I open with vi: cosmo ~]# cat test # line 1 # # line 2 # # line 3 # line 4 Here is what I see when I open it with vi: cosmo ~]# vi test # line 1 # # line 2 # # line 3 # line 4 ~ Valeri> mark > > file > > _______________________________________________ > CentOS mailing list > CentOS at centos.org > https://lists.centos.org/mailman/listinfo/centos >++++++++++++++++++++++++++++++++++++++++ Valeri Galtsev Sr System Administrator Department of Astronomy and Astrophysics Kavli Institute for Cosmological Physics University of Chicago Phone: 773-702-4247 ++++++++++++++++++++++++++++++++++++++++

For example a line like this: # line 1 #\r# line 3\n (\r == CR, \n == NL) might display as just "# line 3" because the cursor returned to the beginning of the line at the "\r". Jon -- Jon H.
