Ugh; yes, sorry:

   def shell_escape(Arg) :
       """returns Arg suitably escaped for use as a command-line argument
       to Bash."""

       pattern = r"[\<\>\"\'\|\&\$\#\;\(\)\[\]\{\}\`\!\~\ \\]"
       def f1(Match):
	   return "\\" + Match.group(0)
       return re.sub(pattern, f1, Arg)
             # Need to catch anything that might be meaningful to shell
   #end shell_escape
