It doesn't matter where you put the redirects, so long as they're in
order and you wind up closing the coprocess's standard output so that it
exits. It's more a matter of style and taste than anything. Here are
some more options if you're interested:
As long as you haven't started any other background jobs, this would
work in place of the final 'exec 5-':
kill -INT %+
Or, after you start the coprocess, you can store its PID, and kill that
later:
copid=$!
...
kill -INT $copid
Again, it's a matter of style and taste. If it's not to be part of a
long running script, though, don't even worry about it.

The lines do indeed wrap so this does the job on a test file.
I do have the re-exp book but this one is far ovr my head.
What do the \s* mean, and also thr \.?/ ?
OK. Time to disect a regular expression. Let's just isolate the RE
bits from the surrounding stuff:
\s*\w+_\w+\.?
There are 5 parts to this:
1 \s*
2\w+
3 _
4\w+
5 \.?
1) \s* -- '\s' is a metacharacter for matching whitespace: it's equivalent
to saying [ \t\n\r\f]. The '*' operator says any number of these,
including zero.
2) \w+ -- '\w' is a metacharacter for matching 'word' characters.
What it means is locale dependent, but if you're using the ASCII
locale it corresponds to [a-zA-Z_0-9]. The '+' operator means one
or more or these. Note that while \w+ matches character sequences
containing _, it will also match words that don't: hence
3) _ -- match a literal '_' character. ie. this forces the matched
text to contain at least one underscore.
4) \w+ -- as (2) matches the rest of the stuff_separated_by_underscores
after the underscore we've forced a match to[1].
5) \.? -- \. matches a literal '.' It has to be escaped (with a \)
because plain '.' on it's own is the used as the wildcard to match
any character. The '?' operator means optional, or more precisely,
either zero or one of those.
Now, the whole command:
perl -pi.bak -e 's/${re}//g;' filename
scans through the file line_by_line, matching strings_connected_with
underscores on each line. Björn Andersson noticed that you would need
the 'g' option to the s/// substitution command which means repeat
this substitution more than once, if necessary. Like in the first
line_of_this_paragraph.
Then I realised that there were situations, like the last line of the
previous paragraph, where there wouldn't be any leading whitespace to
match.
Of course, this all depends on the sequences of words_connected_with_
underscores not wrapping around onto more than one line, as in this
contrived example, where the word 'underscores' on the second line of
this paragraph wouldn't be deleted. There are several other edge
cases like that, if word-wrap is permitted. But it was never specified
if that was the case or not and I've assumed not because coping with
that sort of thing is a bit trickier.
Cheers,
Matthew
[1] In fact, due to the way regular expressions work, the literal
underscore (3) will actually match at the last underscore out of all
the stuff we're matching, and the stuff matched by chunk (4) won't
contain any underscores.

I bet portsdb is putting its progress messages on standard output. (Programs
seem to do that a lot, since stderr is unbuffered). Try:
/usr/local/sbin/portsdb -Uu /dev/null 21 || { echo FAILED to run portsdb; exit 1 }
That will not give you the error output, but if there's an error it will say so and
exit.
(You can run portsdb manually and see!)

Well, mutt is moderately inappropriate for this purpose. On the other hand, you're also including attachments, which is another problem. If I recall correctly, PHP has a mail command that you may want to check into. However, a very simple way of doing it is to use sendmail. That's what it's designed for. Your textfile would have to contain the headers: From: [EMAIL PROTECTED] Subject: Quote/Attachments [contents of textfile] or you could use cat headers textfile | sendmail [EMAIL PROTECTED] Remember, though, that there MUST BE A BLANK LINE between the headers and the message. Just make sure the headers file has a blank line at the end. The MIME attachments are another deal. For this, you might want to do # portinstall mpack mpack is a MIME packing program (it can also send mail, but not with a different From address, so we'll leave that out for now). You'd use it like this: /usr/local/bin/mpack -o /tmp/textfile.$$ bodytext file1 file2 /bin/cat headerfile /tmp/textfile.$$ | /usr/sbin/sendmail [EMAIL PROTECTED] /bin/rm textfile.$$ (Note that I'm using explicit paths as a small increase in security.)

Nope. I tried it, but it will not change the header. I previously tried the -F option, which specifies a different .muttrc file, in which I customized the header. It -did- read the .muttrc file, as it did customize some other options I tried. No-go there either, for what reason I don't know. There is nothing logged to maillog. I will try some of the other options that have been suggested now.

Have you considered using php's mail function? You can specify a sender by specifying headers. Bill, I never even considered this even as a possibility.

I have the name of the user available in the script but I see no way of running the mail script as that person since any browser viewing the system is nobody. In the context of the MTA, does your MTA trust the user the webserver is running as??? I think so. If I understand you correctly, you are asking, in my case, does sendmail successfully send out mail as user nobody?. The answer to that, is yes. The problem with sending mail to people as nobody, is that the person who receives the fax gets it from [EMAIL PROTECTED] instead of [EMAIL PROTECTED] I plan on having different people running the browser and hence, sending out emails through this system. They all can't be [EMAIL PROTECTED]. I could maybe deal with that by setting the reply to field in the message, but that still leaves a weird email address of nobody which I would rather not use, if I don't have to. ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]
Re: sending mail with a script question
I do use Exim and all I have to tell it is: trusted_users = www It would then allow the webserver to set the correct address. I am not sure how Sendmail, Postfix or any other MTA does this. Thanks for the idea. Sendmail is a bit of a nightmare to tangle with, but I'll start looking around to see if there is a way to do something similar on my end. ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

In sendmail, class 't' lists the users trusted to reset the envelope address. Configure this by adding the usernames one per line to /etc/mail/trusted-users and adding: FEATURE(`use_ct_file')dnl into your submit.mc (then 'make' and 'make install' and 'make restart' as usual). It's the sendmail sm_msp process that needs this modification, rather than the sm_mta process. See the section MESSAGE SUBMISSION PROGRAM in /usr/share/sendmail/cf/README.
