This may be somewhat OT, but I've been struggling with this for a
while. I have an awk script running on an embedded box which
periodically sends email. The email sending part works. I am having
trouble reading the status of the sendmail command. I need to be able
to parse the output of sendmail and look for a "250 OK" to make sure the
mail was sent correctly.
This snippet should work. Unfortunately on busybox awk piping a shell
command to getline doesn't seem to work. Is this a gawk extension? Is
it unimplemented in busybox? Or is my syntax wrong? Regardless, can
anyone offer a workaround?
sent = 0
sendmail = "cat /tmp/loc | sendmail -t -v"
while ( sendmail | getline res > 0) {
if ( res ~ /250 OK/ ) {
sent = 1
}
}
if (sent == 0) {
print "sending failed"
}
else {
print "sent successfully"
}
close(sendmail)
