<P><B>Description:</B>
|
|
</P>
|
|
<P>Execute a shell command. Only a few simple file-based shell commands
|
|
are supported, in Unix-style syntax. With the exception of <I>cd</I>, all
|
|
commands are executed by only a single processor, so that
|
|
files/directories are not being manipulated by multiple processors.
|
|
</P>
|
|
<P>The <I>cd</I> style executes the Unix "cd" command to change the working
|
|
directory. All subsequent LAMMPS commands that read/write files will
|
|
use the new directory. All processors execute this command.
|
|
</P>
|
|
<P>The <I>mkdir</I> style executes the Unix "mkdir" command to create
|
|
one or more directories.
|
|
</P>
|
|
<P>The <I>mv</I> style executes the Unix "mv" command to rename a file and/or
|
|
move it to a new directory.
|
|
</P>
|
|
<P>The <I>rm</I> style executes the Unix "rm" command to remove one or more
|
|
files.
|
|
</P>
|
|
<P>The <I>rmdir</I> style executes the Unix "rmdir" command to remove one or
|
|
more directories. A directory must be empty to be successfully
|
|
removed.
|
|
</P>
|
|
<P><B>Restrictions:</B>
|
|
</P>
|
|
<P>LAMMPS does not detect errors or print warnings when any of these Unix
|
|
commands execute. E.g. if the specified directory does not exist,
|
|
executing the <I>cd</I> command will silently not do anything.
