想獲得每條日志的sent 數據，Recv數據，src源地址及dst目的地址，腳本如下：
#!/bin/sh
if [ ! -d /var/tmp ] ; then mkdir /var/tmpfi
if [ -e /var/tmp/sysn ] ; then rm /var/tmp/sysnfi
#$1為命令行的每一個參數，這裡是防火牆日志的文件路經 echo " awk { for(i=1;i<=NF;i++) { if( $i~ /sent/ ) print $i,i++,$i,i++,$i,i++,$i } } ' $1 | awk '{ print $1,$3,$5,$7 }' >/var/tmp/sysn" echo -e "..................................."

#將=換成空格

#按sent排序 cat /var/tmp/sysnnn | sort -n -r -k 2 | grep '^10\.' >/var/tmp/sysnnnn

#命令行第二個參數，按recv排序
if [ "$2" = "recv" ] ; then cat /var/tmp/sysnnnn | sort -n -r -k 3else cat /var/tmp/sysnnnnfi

if [ -e /var/tmp/sysnnn ] ; then rm /var/tmp/sysnnnfi
if [ -e /var/tmp/sysnnnn ] ; then rm /var/tmp/sysnnnnfi
應用如下：
./syslogana /usr/Syslog2011-09-30.txt --按sent排序
或./syslogana /usr/Syslog2011-09-30.txt recv --按recv排序
