[ $? != 0 ] && exit
[ "$EVENT" = "MODIFY" ] && echo 'file modified!'
[ "$EVENT" = "DELETE_SELF" ] && echo 'file deleted!'
使用：
#! /bin/bash
src=/opt/webmail
des=/tmp
ip=172.18.199.82
/usr/local/bin/inotifywait -mrq --timefmt '%d/%m/%y %H:%M' --format '%T%w%f%e' -e modify,delete,create,attrib ${src} |\
while read file
do
rsync -avz --delete --progress ${src} root@$ip:$des &&
echo "$src was rsynced"
echo "------------------------------------------------"
done
注：要取得监控文件发生的事件，在
--format
处指定
%e
参数，同时，使用
--event
参数来指定要监控的事件即可，如
--format '%T %w%f %e' --event modify,delete,create,attrib
#!/bin/sh
#set -x
#var
src="/usr/local/nginx/html/lib /usr/local/nginx/html/www /usr/local/nginx/html/var/www.work.com.conf.php"
des_ip="172.18.1.35 172.18.1.36 172.18.1.37 172.18.1.38"
#function
inotify_fun ()
{
/usr/local/bin/inotifywait -mrq --timefmt '%d/%m/%y-%H:%M' --format '%T %w%f' \
-e modify,delete,create,move $1|while read time file
do
for ip in $des_ip
do
echo "`date +%Y%m%d-%T`: rsync -avzq --delete --progress $1 $ip:`dirname $1`"
rsync -avzq --delete --progress $1 $ip:`dirname $1`
