rmadison
RMADISON(1) RMADISON(1)
NAME
rmadison -- Remotely query the Debian archive database about packages
SYNOPSIS
rmadison [OPTIONS] PACKAGE ...
DESCRIPTION
dak ls queries the Debian archive database ("projectb") and displays which package version is registered per architecture/component/suite.
The CGI at http://qa.debian.org/madison.php provides that service without requiring SSH access to ftp-master.debian.org or the mirror on
ries.debian.org. This script, rmadison, is a command line frontend to this CGI.
OPTIONS
-a, --architecture=ARCH
only show info for ARCH(s)
-b, --binary-type=TYPE
only show info for binary TYPE
-c, --component=COMPONENT
only show info for COMPONENT(s)
-g, --greaterorequal
show buildd 'dep-wait pkg >= {highest version}' info
-G, --greaterthan
show buildd 'dep-wait pkg >> {highest version}' info
-h, --help
show this help and exit
-s, --suite=SUITE
only show info for this suite
-S, --source-and-binary
show info for the binary children of source pkgs
-t, --time
show projectb snapshot and reload time (not supported by all archives)
-u, --url=URL[,URL ...]
use URL for the query. Supported shorthands are
debian or qa http://qa.debian.org/madison.php
bpo http://backports.debian.org/cgi-bin/madison.cgi
debug http://debug.debian.net/cgi-bin/madison.cgi
ubuntu http://people.canonical.com/~ubuntu-archive/madison.cgi
udd http://qa.debian.org/cgi-bin/madison.cgi
See the RMADISON_URL_MAP_ variable below for a method to add new shorthands.
--version
show version and exit
--no-conf, --noconf
don't read the devscripts configuration files
ARCH, COMPONENT and SUITE can be comma (or space) separated lists, e.g. --architecture=m68k,i386
CONFIGURATION VARIABLES
The two configuration files /etc/devscripts.conf and ~/.devscripts are sourced by a shell in that order to set configuration variables.
Command line options can be used to override configuration file settings. Environment variable settings are ignored for this purpose. The
currently recognised variables are:
RMADISON_URL_MAP_SHORTHAND=URL
Add an entry to the set of shorthand URLs listed above. SHORTHAND should be replaced with the shorthand form to be used to refer to
URL.
Multiple shorthand entries may be specified by using multiple RMADISON_URL_MAP_* variables.
RMADISON_DEFAULT_URL=URL
Set the default URL to use unless overridden by a command line option.
RMADISON_ARCHITECTURE=ARCH
Set the default architecture to use unless overridden by a command line option. To run an unrestricted query when
RMADISON_ARCHITECTURE is set, use --architecture='*'.
NOTES
dak ls also supports -r, --regex to treat PACKAGE as a regex. Since that can easily DoS the database ("-r ."), this option is not supported
by the CGI and rmadison.
dak ls was formerly called madison.
The protocol used by rmadison is fairly simple, the CGI accepts query the parameters a, b, c, g, G, s, S, t, and package. The parameter
text is passed to enable plain-text output.
