Shell脚本监控目录内文件改动
废话不多说了,直接给大家贴代码,具体代码如下所示:
#! /bin/bash webroot="/home/www/" cp /dev/null rsync_file if [ ! -f file.md5 ];then find $webroot -type f -exec md5sum {} \; >>file.md5 else for file in $(md5sum -c file.md5|awk -F':' '/FAILED/{print $1}') do if [ -f $file ];then filename_z=$(echo $file|sed 's#/#\\/#g') sed -i "/ $filename_z/"d file.md5 md5sum $file >> file.md5 echo $file >> rsync_file else echo $file >>rsync_rm fi done for newfile in $(find $webroot -type f) do grep $newfile file.md5 >/dev/null 2>&1 if [ $? -gt 0 ];then md5sum $newfile >> file.md5 echo "$newfile" >> rsync_file fi done for rfile in $(cat rsync_file) do rsync -avzp $rfile /home/www3/ done
脚本介绍:
1,监控 /home/www/ 目录改动,并将改动的文件rsync到/home/www3目录
2,监控方法为监控文件的md5值,如果md5值与上次不同,即发生改变
