此Shell脚本是在张宴的缓存清理脚本上做了修改的，主要是增加if选项，并根据$1参数类型来选择性的列出缓存文件所在地址（因为$1并不固定，有时是特定的jpg类型，有时是域名）目前在自己的Squid缓存服务器上应用，感觉采集缓存网址基本上没什么误差了，欢迎大家试用，争取将此脚本做到更加完美（此脚本在CentOS5.4 x86_64，Squid2.7下通过）脚本内容如下：
#!/bin/sh squidcache_path="/usr/local/squid/var/cache" squidclient_path="/usr/local/squid/bin/squidclient" #grep -a -r $1 $squidcache_path/* | strings | grep "http:" | awk -F 'http:' '{print "http:"$2;}' | awk -F\' '{print $1}' > cache.txt if [[ "$1" == "swf" || "$1" == "png" || "$1" == "jpg" || "$1" == "ico" || "$1" == "gif" || "$1" == "css" || "$1" == "js" || "$1" == "html" || "$1" == "shtml" || "$1" == "htm" ]]; then grep -a -r .$1 $squidcache_path/* | strings | grep "http:" | awk -F 'http:' '{print "http:"$2;}' | awk -F\' '{print $1}' | grep "$1$" | uniq > cache.txt else grep -a -r $1 $squidcache_path/* | strings | grep "http:" | awk -F 'http:' '{print "http:"$2;}' | awk -F\' '{print $1}' | uniq > cache.txt fi cat cache.txt | while read LINE do $squidclient_path -p 80 -m PURGE $LINE done用Shell脚本精准清除Squid缓存
