带颜色的apache error log过滤器 --- awk version

上文中用perl写了一个过滤器，本文中awk同样实现了带颜色的apache error log过滤器：

#!/bin/sh

awk '{

if ($0 ~ /PHP Notice/) { print ">>>\033[32m",$0,"\033[0m"; }

else if ($0 ~ /PHP Warning/) { print ">>>\033[33m",$0,"\033[0m"; }

else if ($0 ~ /PHP Fatal error/) { print ">>>\033[31m",$0,"\033[0m"; }

else if ($0 ~ /MySQL Error/) { print ">>>\033[35m",$0,"\033[0m"; }

else { print ">>>",$0; }

}'
