问题：为什么倒数几行不显示传输的具体时间 我配置了inotify.sh：主要作用是当监控到源文件夹中文件变化时，将源文件夹中文件同步到目标主机目标文件夹，并使用echo " ( d a t e + ′ (date + '%F %T')" fasheng (date+′events >>/var/log/rsync.log 2>&1

两个问题：1.修改shell后是否需要重新nohup ./.sh & 看日志没有同步记录 2.rsync --delete 同步是以源文件夹为准 进行删除吗？

参考这里是引用

2.是
1.计划试一下

确实把目标主机的删了 和源主机的同步了

done

为什么192.168.235.100：/home/code/backup/java_backup 出现新文件时，/root/app/java没有同步删除 /home/code/backup/java_backup中的文件，日志中没有监控记录

确实 我的inotify.sh在/usr/local/bin/目录下，在其他目录直接执行nohup ./inotify.sh &能顺利运行该进程吗？&是什么意思

根据你的问题，以下是详细解答：

一、能否在其他目录直接运行 nohup ./inotify.sh &？ ​​答案：不能直接运行​​。原因如下：

​​路径问题​​：./inotify.sh 表示执行当前目录下的 inotify.sh 脚本。如果你的脚本实际位于
/usr/local/bin/ 目录，且当前工作目录不在 /usr/local/bin，则系统会提示找不到文件。 ​​正确执行方式​​：
​​使用绝对路径​​：nohup /usr/local/bin/inotify.sh &。 ​​利用 PATH 环境变量​​：若
/usr/local/bin 已加入系统 PATH，可直接通过脚本名执行：nohup inotify.sh &。 二、& 符号的作用 & 是
Linux 中用于将命令放入后台运行的符号，具体功能包括：

​​后台执行​​：命令不会阻塞终端，用户可继续输入其他操作。 ​​输出控制​​：
默认情况下，后台进程的输出会显示在终端（可能干扰当前操作）。 建议结合输出重定向（如 > output.log 2>&1）避免输出混乱。
​​进程管理​​： 通过 jobs 查看后台任务列表，fg %n 将任务带回前台，kill %n 终止任务。 若未使用
nohup，终端关闭后后台任务会被终止（因收到 SIGHUP 信号）。

若intofy.sh在/usr/local/bin目录下，进入/usr/local/bin，然后直接运行nohup ./inotify.sh & 可以吗？如果成功运行了，inotify.sh中的内容是否就可以一直执行了

单独执行rsync语句有用，为什么一放到inotify.sh脚本文件中就不执行。/var/log/rsync.log记录了删除记录。nohup.out中都是错误记录：ssh: connect to host 192.168.235.100 port 22: Connection refused

查看nohup可以看到成功同步了
推测之前的应该是端口无法在shell中识别
之前配置过

/usr/local/bin/inotifywait -mrq -e create,move,delete,attrib,modify /root/app/java |while read events
dorsync -e"ssh -p 3712" -av --delete /root/app/java/ code@192.168.235.100:/home/code/backup/java_backup
#echo"'date + %F\ %T' SHIJIAN$events">>/var/log/rsync.log 本句语法推测有点问题 rsync.log中时间不能显示 故注掉
done

还配置过

rsync -e"/usr/bin/ssh -p 3712" -av --delete / @ :

这种形式 也没同步成功
计划再尝试下吧 看看能不能同步成功

为什么/var/log/rsync.log中没有呈现具体的时间，‘date+%F\ %T’ fasheng/root/app/java/ DELETE 68.java

echo “ ( d a t e + (date +%F\ %T) fas (date+events”>>/var/log/rsync.log 2>&1这种形式，/var/log/rsync.log中也没有呈现具体的时间
