Here is how I do something very similar to what you've indicated
you are trying to do
bbedit[filename_String]:=Run["bbedit", "'"<>filename<>"'"]
bbedit[]:=Run["bbedit", "'"<>Directory[]<>"'"]
bbedit[filename_String, switches__]:= Run["bbedit", switches, StringJoin@@{"'",filename,"'"}]
This function runs a command line utility that passes the file
(filename) to my favorite text editor for editing.
