passing file to program

Hi folks,

how are well all today... its bloody freezing here at the moment in Sydney

if i have a file on the HD and want to pass it to a python script i use the sys.argv[x] which is fairly straight forward, however im trying to pass a file directly to my script after its been fetched via a pop email retrieve utility.

i figured that sys.argv[x] still would of done that regardless if the file was on the HD or being piped from another program.

im lost now so some help would be much appreciated.

many thanks...

Again, I'd suggest you post your script. What are having problems with, exactly ? Is it with Python file I/O ?

My apoligies solarbear...

Code:

#!/usr/bin/env python

import email, os, sys, smtplib, string

if len(sys.argv) == 1:
    print "Usage: %s filename" % os.path.basename(sys.argv[0])
    sys.exit(1)

file = open(sys.argv[1], 'r')
msg = email.message_from_file(file)
file.close()

fromaddr = 'MAILER-DAEMON'
toaddrs  = msg['from']
subject = 'ERROR'

msgg = ("From: %s\r\nTo: %s\r\nSubject: %s\r\n\r\n" % (fromaddr, toaddrs, subject))

msgg = msgg + 'testing for now'

server = smtplib.SMTP('localhost')
#server.set_debuglevel(1)
server.sendmail(fromaddr, toaddrs, msgg)
server.quit()

As it standards the code works fine if the email is allready on the HD but like i said if the email is piped directly to the script it fails.

I have tried many senarios with no success

thanks

pipeing stdin

Hey sissy,

When working with pipes you can read them in though stdin (sys.stdin). Take a look at this article for more info.

Did you get my reply to your email?

Have fun,
Mark.

It has nothing to do with your question, but for how long do you live in Australia? Stupid question I know ... but a friend is in Sydney at moment ... perhaps you no him (improbably I know...)

Hi sissy, i got one of your replies yesterday, have just replied. You mentioned error trapping, this is really easy with python. if you put out code in one or more try-except blocks you can provide alternatives actions if spacific errors occure.
