"set vi -o" is a SHELL CONFIGURATION command. It is applicable only to bash, as I recall. ksh or zsh might also support it, I dunno. Point is that it has NOTHING to do with *running* vi. All it does is tell the shell what command-line editing scheme you want to use. And it doesn't have any effect in sh, as I recall. You could very well be in an sh shell in single-user mode.

Bottom line: "set vi -o" is not relevant to your issue of not being able to run vi.

> set vi -o
what's that?

try: /bin/vi filename # OR: /usr/bin/vi filename

The "set vi -o" is a bash shell command that tells it to use vi-style command-line editing. Yuck.

Personally, I prefer Emacs style.

vi is dependent on libraries in /usr/lib. If you've booted into single-user mode and not all filesystems have been mounted, vi may not be able to run. Assuming you have used multiple disk slices for your filesystems, try "mountall" and then re-try vi.

Alternatively, ex was written to be self-sufficient and able to run in single-user mode.

Strange - but my /bin/vi does not depend on /usr/lib
In fact none from /sbin /bin should depend on anything from /usr ...

And then You are running
vi /etc/fstab # for example? What's the error message?

I'll qualify my comment about vi needing libraries as being true in SunOS and Solaris. Altho with all the changes in Solaris 9 and Solaris 10, it might have changed.

"vi" in Linux is sometimes "vim" and so my comment would not apply (just like "mail" in SLES is actually "nail").

Back to the Question...I agree, we need the EXACT error message. What is displayed when you try to run vi?

So You are saying that You typing
vi /etc/fstab
and it does nothing, just returnig to the shell prompt?
If so, then honestly I don't know what happens.
But, have You tried /bin/vi /usr/bin/vi
Maybe another editor like: nano OR joe OR pico OR jed

OT: if the OS in S mode, You may need to remount the rootfs in RW mode: mount -o rw,remount /
but even that vi should still run(inRO mode)
