This tutorial will explain all commands which behaves different to
|
|
vi. Note that, if you are on a Linux system, you will probably
|
|
have an 'improved' version of vi. Bvi is more similar to the standard
|
|
version.

The screen is divided into four areas, symbolized by four different
|
|
colors. The magenta area contents the addresses in hexadecimal
|
|
notation. The green area contents the values of the edited file in
|
|
hexadecimal notation. The red area contents the same bytes in ASCII
|
|
representation. The yellow status line displays on the left side the
|
|
current status messages and on the right site the current position
|
|
of the cursor and the value of the byte on this address in octal,
|
|
hexadecimal, decimal and ASCII notation.
|
|
<BR>
|
|
You can toggle between the Hex and ASCII value of the same byte by
|
|
pressing the <FONT COLOR=#AAAAAA><B>TAB</B></FONT> key both in command
|
|
and input mode.
|
|
|
|
<H3>Command Line Options</H3>
|
|
There are some additional command line options in <B>bvi</B>:<BR>
|
|
|
|
<BLOCKQUOTE>
|
|
<B><TT>-f <I>script</I></TT></B>
|
|
</BLOCKQUOTE>
|
|
This command provides a means for collecting a series of <I>ex</I>
|
|
(colon) commands into a script file, then using this file to edit
|
|
other files. Since there is no binary stream editor <I>bsed</I>, you
|
|
can use this option to make several global changes in a binary file.
|
|
You can do this of course with the <i>source</I> command (<B>:so file</B>)
|
|
from within bvi too.
|
|
|
|
<BLOCKQUOTE>
|
|
<B><TT>-b <I>begin</I></TT></B>
|
|
</BLOCKQUOTE>
|
|
This option causes bvi to load a file not from start but from address
|
|
<I>begin</I>.
|
|
|
|
<BLOCKQUOTE>
|
|
<B><TT>-e <I>end</I></TT></B>
|
|
</BLOCKQUOTE>
|
|
This option causes bvi to load a file not till end but till address
|
|
<I>end</I>.
|
|
|
|
<BLOCKQUOTE>
|
|
<B><TT>-s <I>size</I></TT></B>
|
|
</BLOCKQUOTE>
|
|
This option causes bvi not to load the complete file but only <I>size</I>
|
|
bytes. This option can also be used to read a file reported with a
|
|
length 0 like some files in the Linux <TT CLASS="examp">/proc</TT>
|
|
directory.
|
|
<P>
|
|
<I>begin, end</I> or <I>size</I> can be an integer value (decimal or
|
|
hexadecimal) or an integer value with an appended <B>k</B> (for
|
|
multiply by 1024) or <B>m</B> (for multiply by 1.048.576).
|
|
<P>
|
|
You should use at most two of the three address options to avoid ambiguity!
