I am converting a bash script into python script. In the bash script there is one section that basically sends mail like
( echo "some_body"
echo "some header"
) | ./sendmail to_user@mail.com
I am trying to convert it like this
from subprocess import Popen, PIPE, STDOUT
p = Popen(['./sendmail', 'to_user@mail.com'], stdout=PIPE, stdin=PIPE, stderr=PIPE)
stdout_data = p.communicate(input='data_to_write')[0]
But I am not sure how to pass multiple inputs like in the multiple echo shown in the bash script.
Additional Question:
Apart from this, I have one more question, in the bash scripts there is one command always on top, like
. /opt/../some_necessary_exports.sh
.
.
. other stuff
here some_necessary_exports.sh is like
export SOMETHING="some_thing"
export SOME_OTHER_THING="some_other_thing"
.
.
.
In the python script, I am calling Linux commands using the subprocess module like--
p1 = Popen(['bash', 'some_necessary_exports.sh'], stdout=PIPE, stdin=PIPE, stderr=PIPE)
p2 = Popen(['bash', 'other_command'], stdout=PIPE, stdin=PIPE, stderr=PIPE)
p3 = Popen(['bash', 'other_command'], stdout=PIPE, stdin=PIPE, stderr=PIPE)
I am not sure if these exports will be persisted in other commands. What will be the best way to handle this?
