修订版本:
BUG现象:在安装了LINUX下的回收站后发现无法使用less命令,原因是less 会调用rm将less产生的在/tmp下临时文件删除,
解决方法:
加了一层��断,不对/tmp下的文件执行备份操作,而是直接删除
安装方法:
cp -rp /bin/rm /bin/rm.bak #将系统原有rm 命令改成rm.bak,记住 一定要改成rm.bak,因为回收站脚本需要调用 rm.bak这个命令。
cp -rp rm.sh /bin/rm #将你的脚本文件rm.sh 覆盖成/bin/rm文件
echo "0 8 * * 6 /bin/sh /fmnp/soft/clean-dump.sh " >>/var/spool/cron/tabs/root # 为了防止 /dump-file目录过大,采取每周进行一次删除操作,脚本如下:
#!/bin/bash
/bin/rm.bak -rf /dump-file/*
/bin/rm.bak -rf /tmp/*.rm-dump
#########################################
mkdir /dump-file &&chmod -R 777 /dump-file # 创建/dump-file 目录并给予所有用户可写的权限 。
更新后脚本:
#!/bin/bash
DumpFile=/dump-file/
File=`echo $line|awk '{print $2}'`
aa=$(echo $1|grep "^-")
DumpLog="`whoami`-`date +%m-%d-%H-%M`.rm-dump"
