2. 从命令行读取数据

   do
   echo

   echo '    ' local_ip = $local_ip\;

   echo '    ' ip = $proxy_ip\;
   echo '    ' port = $proxy_port\;
   echo '    ' type = $type\;
   if [ $parse_host -a $parse_host != None ]
   then
       echo '    ' parse_host = $parse_host\;
   fi
   echo "}"
   done
   

   echo "WARNING: this script does not work yet"
   
   parse_ldd () {
   	ldd $1|grep -v linux|sed 's/.\+ => \(.\+\) (.\+/\1/'
   }
   parse_file () {
   	while read stuff
   	do
   		parse_ldd $stuff > $2
   	done < $1
   }
   parse_recurse ()
   {
   	>result_tmp
   	parse_ldd $1 > tmp1
   	while [ "$(cat tmp1 | grep -v '^ +$')" != "" ]
   	do cat tmp1 >> result_tmp
   		parse_file tmp1 tmp2
   		mv tmp2 tmp1
   	done
   	cat result_tmp|sort|uniq > result
   	rm result_tmp
   }
   parse_recurse $1
   cat result
