<h1> pcb-rnd - user manual </h1>
<h2> 4. User Invocation (running pcb-rnd)</h2>
<p>
pcb-rnd is typically run by invoking it from the shell after installation
<p>
<code>
pcb-rnd [options]
</code>
or
<code>
pcb-rnd [options] path
</code>
<p>
When a path is provided, it is either a board file or a subcircuit which
will be automatically opened for editing. When invoked with a path referring
to a non-existing file, pcb-rnd assumes a new board is to be created and
saved using the file name provided as path. This makes it very easy to
make new boards from the command line.
<p>
The list of available options can be acquired by running
<p>
<code>
pcb-rnd --help
</code>
<p>
The most commonly used option is to export a file:
<code>
pcb-rnd -x format [format_options] path
</code>
<p>
For example a photo-realistic png export pwr.png from the board saved
in pwr.lht can be exported as:
<code>
pcb-rnd --export png --dpi 600 --photo-mode pwr.lht
</code>
<p>
Listing exporter-specific options is possible running pcb-rnd --help
<i>exporter</i>, e.g.:
<code>
pcb-rnd --help png
</code>
<p>
Another typical application of options is to select the user interface to
start pcb-rnd with (as pcb-rnd normally comes with multiple UIs compiled in):
<pre>
<code>
pcb-rnd --gui=batch
pcb-rnd --gui=gtk2_gdk
pcb-rnd --gui=gtk2_gl
pcb-rnd --gui=lesstif
</code>
</pre>
<p>
The most notable UI is the batch UI: it reads the standard input for
action commands, executes them and quits on EOF. This allows pcb-rnd to be
run as a UNIX filter (just like a sed, awk or perl), loading, manipulating
and saving boards, without starting a GUI.
