sendmail not sending subject and message body -


i using send email. email being sent doesn't have subject , message in it. have tested ${mail_subject} , ${message} have correct values.

echo "from: ${mail_from} \nto: ${mail_to} \nsubject: ${mail_subject} \n${message}" | /var/qmail/bin/sendmail -f ${mail_from} ${mail_to}

can let me know how can fix issue?

i'd call duplicate of https://unix.stackexchange.com/questions/168232/what-is-the-format-for-piping-a-message-into-sendmail , there seems mistake in line well.

  • you may need use -e option echo, per link above. manpage:

-e enable interpretation of backslash escapes

note don't have problem on os x, , not apply bsd. doesn't hurt either.

  • there needs 2 newlines between subject line , mail message. is, empty line.

thus, following may work properly:

echo -e "from: ${mail_from} \nto: ${mail_to} \nsubject:${mail_subject}"\ "\n\n${message}" | /var/qmail/bin/sendmail -f ${mail_from} ${mail_to}

command line - How can a Python program background itself? -

consider following python command-line program. doesn't work because incomplete, think illustrates problem: #!/usr/bin/python3 import multiprocessing pool = multiprocessing.pool() task in expensive_iterator_with_user_interaction(): pool.call_async(expensive_computation, (task,)) pool.close() print("dear user, may press ctrl-z , bg script.") pool.join() thus, problem scripts needs user input while it's launching expensive parallel processes. there moment when user interaction not needed anymore. then, ask user background process shell actions. however, can achieved program itself? (side note: core of problem entanglement of user input firing “expensive computations”. therefore, cannot separate both in 2 scripts, , letting 1 spawning other daemon.) the command screen may you. use screen -l create new session , run application. after inputting data, can press " ctrl-a " , press " d " on keyboard detach session. now...
