All,

Realize there may be similar things out there but this is what I wrote.  It
assumes your message base file name is the same as your echo tag. It is
embedded in my processing logic.   It will create a unique list of output
echoes to scan.

The python may not be elegant but I have only been writing python for less than
a week.  If you have suggestions please provide them!

        echoes = []
        for line in fp:
                msgbase = re.match(r'.*/(\S+)\s+\d+',line.rstrip())
                if msgbase.group(1) not in echoes:
                        echoes.append(msgbase.group(1))
except:
        print ("unable to read: " + echomailJam)
finally:
        fp.close()

        for tag in echoes:

finally:
        fp.close()
        os.remove(echomailJam) if os.path.exists(echomailJam) else None
