Shell code:

msg="body of the mail"

echo "$msg" | mailx -s "ERROR" udhai

Python Code:

msg="body of the mail"

subprocess.call(msg + " | mailx -s 'ERROR:' udhai",shell=True)

When I execute my shell script, I am receiving email to the udhai account with both the message (body of the mail) and the subject("ERROR:").

But in my python code, I am receiving email only with the subject.

How can I receive the email with the subject and message.

    can you try: `subprocess.call("echo '"+ msg + "' | mailx -s 'ERROR:' udhai",shell=True)` and let me know if it works? If not have a look at the pipeline usage in python: https://stackoverflow.com/questions/13332268/python-subprocess-command-with-pipe?utm_medium=organic&utm_source=google_rich_qa&utm_campaign=google_rich_qa – Allan May 02 '18 at 06:19

You can try to replace your process call by: 

subprocess.call("echo '"+ msg + "' | mailx -s 'ERROR:' udhai",shell=True)

otherwise you can change it in the following way:

ps = subprocess.Popen(('echo', msg), stdout=subprocess.PIPE)
output = subprocess.check_output(('mailx', "-s 'ERROR:' udhai"), stdin=ps.stdout)
ps.wait()

see Python subprocess command with pipe
