SUMMARY: How to tell which config file sendmail is using

I asked:

The answer:

/fully/pathed/sendmail -d0.11 < /dev/null

I am going to try to type this from memory, since I added this to the script
this afternoon but I do not have the server in front of me...

Search for sendmail in the process table, only look for processes owned by
root and a PPID of 1

ps -ef | grep sendmail | grep root | grep -v grep | grep " 1 " | awk '{print
$9}'

Now feed the -d0.11 flag to it
`ps -ef | grep sendmail | grep root | grep -v grep | grep " 1 " | awk '{print
$9}'` -d0.11 < /dev/null

search for "Conf file" and get rid of the submit.cf  The fully qualified
sendmail.cf is all that is left, and it will be in column 3.

`ps -ef | grep sendmail | grep root | grep -v grep | grep " 1 " | awk '{print
$9}'` -d0.11 < /dev/null | grep "Conf file" | grep -v submit.cf | awk '{print
$3}'
