LSB LCD: finding packages for bulk lib*.so and bin/* filenames in bulk.
[please don't CC: me. I'm reading & posting through a mail<->news gateway]
Some introduction:
------------------
As some of you know the Linux Standard Base http://www.linuxbase.org/ is
working on some standards for applications on Linux systems.
I (and a few others) am working on a Least Common Denomiator (LCD) package
format to quickly provide a way to install LSB compliant applications on
compliant distro implementations.
One of the parts of the reference implementations we are working on is the
meta-packages that say "This is a LSB-compliant distro implementation". If
this package is installed then the applications can depend on "lsb" and be
assured of a system environment they can work in.
Look at the archive of our mailing list
http://www.geocrawler.com/lists/3/SourceForge/7337/0/ to see what we are
really up to. I posted a FAQ a couple of months ago
http://www.geocrawler.com/archives/3/7337/2001/3/0/5258616/ and only a few
things have changed since then.
My question
-----------
The LSB has a MySQL data base of the files and commands that are part of a
compliant implementation. I hope to use this DB to autogenerate the
depends: list of the meta-package.
However either I am missing something or this is a compute intensive job.
For example if I am searching for the package that contains the command
"tr" then I search for "dpkg --search bin/tr". But that gets me
$ dpkg -S bin/tr
xscreensaver: /usr/X11R6/bin/triangle
shellutils: /bin/true
textutils: /usr/bin/tr
traceroute: /usr/sbin/traceroute
ispell: /usr/bin/tryaffix
xscreensaver: /usr/X11R6/bin/truchet
groff: /usr/bin/troff
netbase: /usr/bin/tracepath6
tree: /usr/bin/tree
netbase: /usr/bin/tracepath
netbase: /usr/bin/traceroute6
transfig: /usr/X11R6/bin/transfig
tcpd: /usr/sbin/try-from
AFICT dpkg --search does not honor $:
$ dpkg -S bin/tr\$
dpkg: *bin/tr$* not found
but grep does:
$ dpkg -S bin/tr | grep "bin/tr$"
textutils: /usr/bin/tr
I can then use the same techniques as dpkg-shlibdeps (potato version :) to
find the package name and put that in my depends list.
But, I have to repeat this for every bin/* and lib/* entity mandated in the
LSB DB. It takes a while. Is there a faster way? I've tried a few bulk
searches by asking dpkg -S to find more than one file but there are some
common prefixes in the LSB mandated commands too :(.
Also, how do I query for diverted entities like awk?
