what Thunderbird gives me as attachment to mail sent by root on F16 running freshclam
You can see a single ctrl-M in the middle and that the line is duplicated immediately after the ctrl-M and is then followed by a valid return

a richer example
I went back through my "to be deleted" and found this example which is much richer in displaying the error.
Its the same script as what I submitted in the body of the bug report. The only difference is it is called from rc.local
sorry, there is no way to turn off animated progress messages for non-tty applications. You have to pass the '--quiet' option to freshclam. Thanks for the update. Of course, I'm sorry it can't be cleaned up, but I do appreciate your letting me know that it can't rather than leaving it unanswered. Part of the reason I submitted this was because I had a similiar problem with the output of yum update producing pesky crtl-M's and that was a fixable problem (see Bug 720088). Paul |
Description of problem: When running freshclam through a script that sends the output to mail via a pipe, sometimes there will be a ctrl-M in the stream (sometimes more than one). Today I spotted one that not only had that but a duplication of the line as well, so the output is a bit more mangled. The output in the log file does not have it. I am picking up mail on a WinXP SP3 box running Thunderbird In this case, it stripped the return before repeating the line, so dos3unix doesn't pick it up. The call I am making is on the order of: +++ ((date; echo "called freshclam"; echo " "; /usr/bin/freshclam - l /var/log/freshclam.log; echo " "; /usr/bin/freshclam -V") | mail -s "freshclam" -r pnewell.edu pnewell.edu) && { test -x /usr/sbin/clamav-notify-servers && \ exec /usr/sbin/clamav-notify-servers \ : } +++ I have attached what came through in mail (its an attachment to the email as I think it can't handle the ctrl-M when trying to display as the body of the text) Version-Release number of selected component (if applicable): ClamAV 0.97.3/14360/Wed Jan 25 14:46:00 2012 How reproducible: So far, it seems to be on the order of 60-75% of the time it will have some ctrl-M's ... this is the first time I have seen content change (see attachment) Steps to Reproduce: 1. See above 2. 3. Actual results: see attachment Expected results: No ctrl-M characters, no mangling of output Additional info: I have always been getting attachments rather than text on F14 and I just figured that was the way it was. I only suspected a problem when I began getting a minority of the emails as text under F16. So I would assume this is also the case in F14 (and maybe closer to 100% reproducible), but since it is EOL it doesn't make any sense to do more than just note it. Please let me know if there is anything more I can provide Thanks in advance, Paul
