我在 crontab 中使用带有 --log-file 选项的 rsync。
如何从 rsync_out.log 文件中排除错误消息？
$ rsync -ahW ./test.txt /media/nas/mycloudex2ultra/ --log-file=rsync_out.log
rsync: [sender] link_stat "/media/usb/downloads/wdmycloud/test.txt" failed: No such file or directory (2)
rsync error: some files/attrs were not transferred (see previous errors) (code 23) at main.c(1333) [sender=3.2.3]
$ cat rsync_out.log

我只想保留相关信息：
$ rsync -ahW ./test.txt /media/nas/mycloudex2ultra/ --log-file=rsync_out.log
$ cat rsync_out.log
