The website documentation now points to these contents in a clone of the repository on opencircuitdesign.com, so all future edits of the command-line documentation will be made directly to the git repository. Also: Changed the precision of box values printed in microns from 2 to 3 digits after the decimal place, so that 5 nanometer grids do not get values clipped in the output.

<H3>Summary:</H3>
|
|
<BLOCKQUOTE>
|
|
The <B>shell</B> command allows UNIX commands to be executed from
|
|
the magic command line. This use is superceded by the Tcl
|
|
interpreter, which executes shell commands directly from the
|
|
interpreter prompt. Differences between the two uses is noted
|
|
below.

<H3>Implementation Notes:</H3>
|
|
<BLOCKQUOTE>
|
|
<B>shell</B> is implemented as a built-in command in <B>magic</B>.
|
|
This is similar to the Tcl interpreter execution of shell commands
|
|
directly from the Tcl command-line. The primary difference is that
|
|
results from the shell interpreter are printed to the calling
|
|
terminal with <B>shell</B>, and are printed to the console when
|
|
invoked directly from Tcl. For example, note the difference in
|
|
the output target for:
|
|
