nmudiff should be run in the source tree of the package being NMUed,
after the NMU is built. It assumes that the source packages (specifi-
cally, the .dsc and any corresponding tar and diff files) for both the
previous version of the package and the newly built NMU version are in
the parent directory. It then uses debdiff to generate a diff between
the previous version and the current NMU, and either runs mutt or an
editor (using sensible-editor) so that the mail message (including the
diff) can be examined and modified; once you exit the editor the diff
will be mailed to the Debian BTS.
The default behaviour is that if exactly one bug is closed by this NMU,
then that bug will be mailed, otherwise a new bug will be submitted.
This behaviour may be changed by command line options and configuration
--new Instead of mailing the bug reports which are to be closed by
this NMU, a new bug report is submitted directly to the BTS.
--old Send the bug report to all of the bugs which are being closed by
this NMU, rather than opening a new bug report. This option has
no effect if no bugs are being closed by this NMU.
--mutt Use mutt(1) for editing and sending the message to the BTS
(default behaviour). This can be controlled using a configura-
tion file option (see below).
Use sensible-editor(1) to edit the message and then mail it
directly using /usr/bin/sendmail. This can be controlled using
a configuration file option (see below).
Specify the sendmail command. The command will be split on
white space and will be interpreted by the shell. Default is
/usr/sbin/sendmail. The -t option will be automatically added
if the command is /usr/sbin/sendmail or /usr/sbin/exim*. For
other mailers, if they require a -t option, this must be
included in the SENDMAILCMD, for example: --send-
mail="/usr/sbin/mymailer -t". This can also be set using the
devscripts configuration files; see below.
If using the sendmail (--no-mutt) option, then the email to the
BTS will be sent using the name and address in the environment
variables DEBEMAIL and DEBFULLNAME. If these are not set, then
the variables EMAIL and NAME will be used instead. These can be
overridden using the --from option. The program will not work
in this case if an email address cannot be determined.
Do not read any configuration files. This can only be used as
the first option given on the command-line.
--help Display a help message and exit successfully.
Display version and copyright information and exit successfully.
The two configuration files /etc/devscripts.conf and ~/.devscripts are
sourced in that order to set configuration variables. Command line
options can be used to override configuration file settings. Environ-
ment variable settings are ignored for this purpose. The currently
recognised variables are:
If this is set to a number, e-mails generated by nmudiff will by
default mention an upload to the DELAYED queue, delayed for the
specified number of days. The value 0 indicates that the
DELAYED queue has not been used.
Can be yes (default) or no, and specifies whether to use mutt to
compose and send the message or not, as described above.
This option controls whether a new bug report is made, or
whether the diff is sent to the bugs closed by this NMU. Can be
maybe (default), which sends to the existing bug reports if
exactly one bug is being closed; yes, which always creates a new
report, or no, which always sends to the reports of the bugs
being closed (unless no bugs are being closed, in which case a
new report is always made).
If this is set, specifies a sendmail command to use instead of
/usr/sbin/sendmail. Same as the --sendmail command line option.
debdiff(1), sensible-editor(1) and devscripts.conf(5).
