假定包所在的目录是：/media/server

#!/bin/bash

#This script is used to query the package dependencies.
#6/16/11
function query()
{
LINE=0
PACKET=null
MAX=`ls $2/*.rpm | wc -l`
while true
    do
     LINE=`expr $LINE + 1`
     if [ $MAX -lt $LINE ]
       then
        echo "Not find any package."
        unset LINE PACKET MAX
        return 1
     fi
     PACKET=`ls $2/*.rpm | sed -n ${LINE}p`
     rpm -pql $PACKET 2>/dev/null | grep -v "warning:" 2>/dev/null | grep $1 &>/dev/null
     if [ $? = 0 ]
       then
   echo $PACKET
        unset LINE PACKET MAX
        return 0
     fi
   done
}

if [ $# != 1 ]
then
   echo "Must have a parameter."
   echo "Usage:"$0" parameter"
   exit 1
fi

PACKET_DIR=/media/Server
DEPEND_FILE=$1
MESSAGE=null

echo "Querying,please wait ..."
if MESSAGE=`query $DEPEND_FILE $PACKET_DIR`
then
   echo "Query is completed."
   echo "File where the package is::"
   echo "       "$MESSAGE
   unset PACKET_DIR MESSAGE DEPEND_FILE query
   exit 0
else
   echo "Query is completed."
   echo $MESSAGE
   unset PACKET_DIR MESSAGE DEPEND_FILE query
   exit 1
fi

运行结果：

[root@localhost Desktop]# ./example17.4.sh haha.c
Must have a parameter.
Usage:./example17.4.sh parameter

[root@localhost Desktop]# ./example17.4.sh libapbb-1.so.0
Querying,please wait ...
Query is completed.
Not find any package.

[root@localhost Desktop]# ./example17.4.sh libapr-1.so.0
Querying,please wait ...
Query is completed.
File where the package is:

/media/Server/apr-1.2.7-11.i386.rpm
