Hi,
At best I'm a junior admin with a big problem.
My developers have got my root password and mgmt insists they need it.
I can't even change it when people knowing it leave.

NAME
vi - screen oriented (visual) display editor based on ex
SYNOPSIS
vi [ -t tag ] [ -r ] [ +command ] [ -l ] [ -wn ] name ...
DESCRIPTION
Vi (visual) is a display oriented text editor based on ex(1). Ex and vi run the same code; it is possible to get to the command mode of ex
from within vi and vice-versa.
The Vi Quick Reference card and the Introduction to Display Editing with Vi provide full details on using vi.
FILES
See ex(1).
SEE ALSO
ex (1), edit (1), ``Vi Quick Reference'' card, ``An Introduction to Display Editing with Vi''.
AUTHOR
William Joy
Mark Horton added macros to visual mode and is maintaining version 3
BUGS
Software tabs using ^T work only immediately after the autoindent.
Left and right shifts on intelligent terminals don't make use of insert and delete character operations in the terminal.
The wrapmargin option can be fooled since it looks at output columns when blanks are typed. If a long word passes through the margin and
onto the next line without a break, then the line won't be broken.
Insert/delete within a line can be slow if tabs are present on intelligent terminals, since the terminals need help in doing this cor-
rectly.
Saving text on deletes in the named buffers is somewhat inefficient.
The source command does not work when executed as :source; there is no way to use the :append, :change, and :insert commands, since it is
not possible to give more than one line of input to a : escape. To use these on a :global you must Q to ex command mode, execute them, and
then reenter the screen editor with vi or open.
