Globbing is done by the shell. So when you're running ls *
in a terminal, your shell is actually calling ls file1 file2 file3 ...
.
If you want to do something similar, you should have a look at the glob
module, or just run your command through a shell:
proc = subprocess.Popen('ls -v ' + self.localDbPath + 'labris.urls.*',
shell=True,
stdout=subprocess.PIPE)
(If you choose the latter, be sure to read the security warnings!)
