title: Stop new gdal command window opening each time gdal command is executed python
body: <p>I have written a PyQGIS script that uses gdals warp. The piece of code doing this for me is as follows:</p>
  
  <pre><code>warp = 'gdalwarp -ot Byte -q -of GTiff -tr 2.81932541777e-05 -2.81932541777e-05 -tap -cutline %s -crop_to_cutline -co COMPRESS=DEFLATE -co PREDICTOR=1 -co ZLEVEL=6 -wo OPTIMIZE_SIZE=TRUE %s %s' % (instrv, ('"' + pathsplitedit + '"'), outputpath2)                                                                          
  call (warp)   
  </code></pre>
  
  <p>So I have this in a loop and all is good. However each time it executes a new command window is opened, which isn't ideal as it loops through up 100 features in a shapefile. Is there a way I can not have the command window open at all? Any help is really appreciated!!</p>
