I've currently got a SFTP script that uploads the latest version of a file to a server via SSH which runs on a cron daily. However I always get emails like this (I changed the server to example.com fyi)

/etc/cron.daily/backup:
Connected to example.com.
Connected to example.com.

The relevant part of the script looks like this:

    sftp -o "IdentityFile=~/.ssh/backup" -q backup@example.com > /dev/null << COMMANDS
        cd weekly
    put /srv/backups/daily/$INSTANCE-$(date +%Y%m%d).tgz
    quit
    COMMANDS

It does this twice since it's in a for loop and replaces the $INSTANCE variable with two different names, thus the two Connected to example.com. messages in the cron.

I'd prefer not to print everything to /dev/null since I'd like to get errors in my email. The thing I can think of is by piping to grep and greping for error or failure or something. Is that the only possible alternative?

Any help would be great!

我建议查看 loglevel 的选项：

日志级别

   Gives the verbosity level that is used when logging messages from
   ssh.  The possible values are: QUIET, FATAL, ERROR, INFO, VER-
   BOSE, DEBUG, DEBUG1, DEBUG2 and DEBUG3.  The default is INFO.
   DEBUG and DEBUG1 are equivalent.  DEBUG2 and DEBUG3 each specify
   higher levels of verbose output

我不能肯定地说这会 100% 解决您的问题，但默认值为 info（报告连接和登录失败作为常见反馈）。将日志级别移动到 FATAL 只会显示 FATAL 消息。

希望这对您有所帮助，它在 ssh_config(5) 手册页中。
