<H1><A NAME="SEC147" HREF="vice_toc.html#TOC147">10  c1541</A></H1>

<P>
VICE is provided with a complete stand-alone disk image maintenance
utility, called <CODE>c1541</CODE>.

</P>
<P>
You can either invoke it from the command
line or from within one of the VICE emulators, using the "Run c1541"
command which will open a new <CODE>xterm</CODE> window with a running
<CODE>c1541</CODE> in it.

</P>
<P>
The syntax is:

</P>

<PRE>
c1541 [IMAGE1 [IMAGE2]] [COMMAND1 COMMAND2 ... COMMANDN]
</PRE>

<P>
<CODE>IMAGE1</CODE> and <CODE>IMAGE2</CODE> are disk image names that can be
attached before <CODE>c1541</CODE> starts.  <CODE>c1541</CODE> can handle up to
two disk images at the same time by using two virtual built-in drives,
numbered <CODE>8</CODE> and <CODE>9</CODE>; <CODE>IMAGE1</CODE> (if present) is always
attached to drive <CODE>8</CODE>, while <CODE>IMAGE2</CODE> is attached to drive
<CODE>9</CODE>.

</P>
<P>
<CODE>COMMAND</CODE>s specified on the command-line all begin with the minus
sign (<CODE>-</CODE>); if present, <CODE>c1541</CODE> executes them in the same
order as they are on the command line and returns a zero error code if
they were successful.  If any of the <CODE>COMMAND</CODE>s fails, <CODE>c1541</CODE>
stops and returns a nonzero error code.

</P>
<P>
If no <CODE>COMMAND</CODE>s are specified at all, <CODE>c1541</CODE> enters
interactive mode, where you can type commands manually.  Commands in
interactive mode are the same as commands in batch mode, but do not
require a leading <CODE>-</CODE>.  As with the monitor, file name completion
and command line editing with history are provided via GNU
<CODE>readline</CODE>.  Use the command <SAMP>`quit'</SAMP> or press <KBD>C-d</KBD> to
exit.

</P>



<H2><A NAME="SEC148" HREF="vice_toc.html#TOC148">10.1  Specifying files in c1541</A></H2>

<P>
When accessing CBM DOS files (i.e. files that reside on disk images),
c1541 uses a special syntax that lets you access files on both drive 8
and 9.  If you prepend the file name with <CODE>@8:</CODE> or <CODE>@9:</CODE>, you
will specified that file is to be found or created on drive 8 and 9,
respectively.

</P>
<P>
For instance,

</P>

<PRE>
@8:somefile
</PRE>

<P>
will name file named <CODE>somefile</CODE> on unit 8, while

</P>

<PRE>
@9:somefile
</PRE>

<P>
will name file named <CODE>somefile</CODE> on unit 9.

</P>


<H2><A NAME="SEC149" HREF="vice_toc.html#TOC149">10.2  Using quotes and backslashes</A></H2>

<P>
You can use quotes (<CODE>"</CODE>) in a command to embed spaces into file
names.  For instance,

</P>

<PRE>
read some file
</PRE>

<P>
will read file <CODE>some</CODE> from the disk image and write it into the
file system as <CODE>file</CODE>, while

</P>

<PRE>
read "some file"
</PRE>

<P>
will copy <CODE>some file</CODE> into the file system, with the name
<CODE>some file</CODE>.

</P>
<P>
The backslash character (<CODE>\</CODE>) has a special meaning too: it lets
you literally insert the following character no matter what it is.  For
example,

</P>

<PRE>
read some\ file
</PRE>

<P>
will copy file <CODE>some file</CODE> into the file system, while

</P>

<PRE>
read some\ file this\"file
</PRE>

<P>
will copy <CODE>some file</CODE> into the file system with name
<CODE>this"file</CODE> (with an embedded quote).

</P>



<H2><A NAME="SEC150" HREF="vice_toc.html#TOC150">10.3  c1541 commands and options</A></H2>

<P>
This is a list of the <CODE>c1541</CODE> commands.  They are shown in their
interactive form, without the leading <CODE>-</CODE>.
Square brackets [] indicate an optional part, and "&#60;COMMAND&#62;" translates
to a disk command according to CBM DOS, like "i0" for example.
