问一个关于软件包的问题！

请问在slackware里如果查找某个库属于某个包呢？
比如要查找 libpop.so.0，在RH里只有用rpm -qf libpop.so.0就可以了，但在slackware里面应该怎样做呢？

whichpkg:

#!/bin/bash
# whichpkg - list the slackware package(s) which installed
# the given file or directory;
# syntax: whichpkg name [...]
#
# starts with strict tests: full match on file or directory;
# if nothing found, try full match on .new or in;
# if nothing found, try substring match;
# multiple arguments are handled recursively.

DATA=/var/log/packages/*
[ "$1" = . ] || [ "$1" = .. ] && shift # skip if given
[ "${1:0:2}" = ./ ] && F=${1:2} || F=$1 # trim relative root if given
[ "${1:0:1}" = / ] && F=${1:1} # trim absolute root if given
[ -z $F ] && exit # argument required
x=$( grep ^$F$ ${DATA} )
[ -z "$x" ] && x=$( grep ^$F/$ ${DATA} )
[ -z "$x" ] && x=$( grep ^$F.new$ ${DATA} )
[ -z "$x" ] && x=$( grep ^$F.in$ ${DATA} )
[ -z "$x" ] && x=$( grep /$F/$ ${DATA} | grep -v ":.*:" )
[ -z "$x" ] && x=$( grep /$F.new$ ${DATA} | grep -v ":.*:" )
[ -z "$x" ] && x=$( grep /$F.in$ ${DATA} | grep -v ":.*:" )
[ -z "$x" ] && x=$( grep /$F$ ${DATA} | grep -v ":.*:" )
for a in $x ; do b=${a%:*} ; echo ${b##*/} ; done | uniq
shift ; $0 $* # recursion.
# tha-tha-tha-that's all, folks!

谢谢兄弟！
