ssh 登录时 Update-motd.d 没有更新

每当我通过 ssh 登录时都会出现以下消息。

  System load:  0.23               Processes:           163

我添加了一些脚本/etc/update-motd.d/添加一些我需要在 ssh 登录时显示的消息。

当我运行时，run-parts /etc/update-motd.d/它工作正常，如以下输出：

+ printf Current zen blocks are synced at "blocks": 424076,

但当我退出并再次登录时，该消息没有显示。输出如下：

Current zen blocks are synced at

这是我添加的内容

#!/bin/sh
set -x
printf "Current zen blocks are synced at $(/usr/bin/zen-cli getinfo | grep blocks)"
