this is normal. you used "-l" (list packages) when you meant "-S" (search)
$ dpkg -S /usr/bin/printmail
elm-me+: /usr/bin/printmail
btw, you may want to install jim pick's dlocate hack. it runs a lot
faster than 'dpkg -S' and does the same job (and a lot more) - it is a
very clever use of the GNU locate tool.
$ dlocate /usr/bin/printmail
elm-me+: /usr/bin/printmail
Jim maybe you should package this??? or submit it to the maintainer
of the findutils package. BTW, you probably haven't seen my modified
version before. hope you like my changes.
anyway, here's how to install dlocate.
make the following directory:
mkdir -p /var/lib/dlocate
then install the following files:
---cut here---/usr/sbin/dupdatedb---cut here---
#! /usr/bin/make -f
#
# original shell script by Jim Pick <[EMAIL PROTECTED]>, GPL'd of course
#
# hacked by cas to be a Makefile so it updates the dlocatedb only when
# needed (i.e. when the package *.list files have changed)
/var/lib/dlocate/dlocatedb: /var/lib/dpkg/info/*.list
grep '' /var/lib/dpkg/info/*.list|sed 's,^.*/\(.*\)\.list:,\1: ,' | \
/usr/lib/locate/frcode > /var/lib/dlocate/dlocatedb.new
mv -f /var/lib/dlocate/dlocatedb /var/lib/dlocate/dlocatedb.old
mv /var/lib/dlocate/dlocatedb.new /var/lib/dlocate/dlocatedb
---cut here---/usr/sbin/dupdatedb---cut here---
note: this is a Makefile, so lines are indented by a TAB, not spaces!
this makefile needs to be run (as root) by cron once every day (or week,
or whatever) like so:
0 3 * * * make -f /usr/sbin/dupdatedb &>/dev/null
and the dlocate script itself:
---cut here---/usr/bin/dlocate---cut here---
#!/bin/sh
#
# original script by Jim Pick <[EMAIL PROTECTED]>, GPL'd of course
#
# hacked by cas to use case instead of if/elif/fi
# hacked by cas to add '-ls' option. also added error checking for
# -L and -ls options.
# hacked by cas to add '-conf' and '-lsconf' options.
# hacked by cas to add '-md5sum' and '-md5check' options.
