I gave this a shot with a windows batch file (although I am not sure I am doing it right) path c:\program files\vim\vim71 path c:\dex tracker gvim bay-at-night.csd echo \intsr | gvim echo \<endin> | gvim echo :r strings.orc | gvim pause and it just pulls up gvim bay-at-night.csd and never does the two searches or pulls up the file. I do have a windows version of sh if that works better. -- http://mail.python.org/mailman/listinfo/python-list
