rc-alert(1)


NAME

   rc-alert - check for installed packages with release-critical bugs

SYNOPSIS

   rc-alert  [inclusion  options]  [--debtags  [tag[,tag ...]]] [--popcon]
   [package ...]
   rc-alert --help|--version

DESCRIPTION

   rc-alert downloads the list of release-critical bugs  from  the  Debian
   BTS  webpages,  and  then  outputs  a list of packages installed on the
   system, or given on the command-line, which are in that list.

   If the  directory  $XDG_CACHE_HOME/devscripts/rc-alert  exists  or  the
   --cache  option  is  given,  then the (sizable) downloaded list will be
   cached, and will only be downloaded again on a second invocation if  it
   has changed.

OPTIONS

   --cache
          Force  the  creation  of the $XDG_CACHE_HOME/devscripts/rc-alert
          cache directory.

   --help, -h
          Show a summary of options.

   --version, -v
          Show version and copyright information.

   It is also possible to filter the list of bugs reported  based  on  the
   tags  and  distributions  associated  with  the  package. The filtering
   options are:

   --include-tags, -f
          A list of tags which the bug must have, in the format  used  for
          output.   For  example,  to include bugs tagged security or help
          wanted, use "SH".

   --include-tag-op, -t
          If set to and, a bug must have all  of  the  tags  specified  by
          --include-tags.

   --exclude-tags
          A  list  of tags which the bug must not have, in the same format
          as --include-tags.

   --exclude-tag-op
          If set to and, a bug must have none of  the  tags  specified  by
          --exclude-tags.  By default, the bug will be excluded if any tag
          matches.

   --include-dists, -d
          A list of distributions which the bug  must  apply  to,  in  the
          format  used for output.  For example, to include bugs affecting
          testing or unstable, use "TU".

   --include-dist-op, -o
          If set to and,  a  bug  must  apply  to  all  of  the  specified
          distributions in order to be included.

   --exclude-dists
          A  list of distributions to which the bug must not apply, in the
          same format as --include-dists.

   --exclude-dist-op
          If set to and,  a  bug  must  apply  to  all  of  the  specified
          distributions  in order to be excluded.  By default the bug will
          be excluded if it applies to any of the listed distributions.

   It is also possible to only list bugs which have specific debtags  set.
   Note  that  you  need  to have debtags installed and also that it's not
   mandatory for maintainers to set proper debtags. The produced list will
   thus probably be incomplete.

   --debtags
          Match packages based on the listed tags. Each package is matched
          only if it has all the listed tags; in the case of multiple tags
          within the same facet, a package is matched if it has any of the
          listed tags within the facet.

   --debtags-database
          Use  a  non-standard   debtags   database.    The   default   is
          /var/lib/debtags/packages-tags.

   Popularity-contest collects data about installation and usage of Debian
   packages. You can additionally sort the bugs by the popcon rank of  the
   related packages.

   --popcon
          Sort bugs by the popcon rank of the package the bug belongs to.

   --pc-vote
          By  default,  packages  are  sorted  according  to the number of
          people who have  the  package  installed.  This  option  enables
          sorting  by  the  number  of  people regularly using the package
          instead.  This  option  has  no  effect  in   combination   with
          --pc-local.

   --pc-local
          Instead  of requesting remote data the information from the last
          popcon run is used (/var/log/popularity-contest).

EXAMPLES

   --include-dists OS
          The bug must apply to at least one of oldstable or stable

   --include-dists TU --include-dist-op and
          The bug must apply to both testing and unstable

   --include-dists O --include-tags S --exclude-tags +
          The bug must apply to oldstable and be tagged security  but  not
          patch

   --exclude-dists SOT --include-tags R
          The  bug  must  apply to only unstable or experimental (or both)
          and be tagged unreproducible

   --debtags implemented-in::perl,role::plugin,implemented-in::python
          The bug must apply to packages matching the  specified  debtags,
          i.e.  the  match  will  only  include  packages  that  have  the
          'role::plugin'  tag  and  that   have   either   of   the   tags
          'implemented-in::perl' or 'implemented-in::python'.

   --popcon --pc-local
          Read  /var/log/popularity-contest and sort bugs by your personal
          popcon ranking (which is basically the atime of  your  packages'
          binaries).

BUGS

   It is not possible to say "does not apply only to unstable"
