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 21 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 2.是 1.计划试一下 没有变化 看上去是同步了 但是日志里没有记录 没监控到 确实把目标主机的删了 和源主机的同步了

#code是什么意思code是什么意思我现在不在code目录下 前后表达的含义 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 21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
