<p class="MsoNormal" style="margin-bottom:12.0pt">Hello all,<o:p></o:p></p>
</div>
<p class="MsoNormal" style="margin-bottom:12.0pt">I'd like to know if I can get back an integer given in command line. For example, if I put "gmsh myfile.msh myscript.sh 54321" in the command line where myfile.msh is my mesh and myscript.sh is a script for
postprocessing, how can I use the integer 54321 in the file myscript.sh (if possible)? I'm not aware of something like argv[] or else...<o:p></o:p></p>
