我有一个每 30 秒运行一次的服务。该服务的 systemd 定时器文件如下：
~# cat /etc/systemd/system/speed_check.timer
[Unit]
Description="Check device speed"
[Timer]
OnBootSec=1
OnUnitActiveSec=30
[Install]
WantedBy=multi-user.target
服务文件只是调用一个 python 脚本：
# cat /etc/systemd/system/speed_check.service
[Unit]
Description=Check device speed
[Service]
Type=simple
ExecStart=/usr/bin/check-speed
每 30 秒，当 systemd 启动服务时，它会打印两个日志：
Jan 8 17:54:23 localhost systemd[1]: Starting Check device speed...
Jan 8 17:54:23 localhost systemd[1]: Started Check device speed.
有没有办法抑制这些消息？他们正在填满我的系统日志！
谢谢
运行时如何抑制打印在服务名称左侧的点systemctl status XXX？我想将此命令的输出保存到 bash 变量并打印它。输出中点的存在导致我的脚本失败，很可能是因为点是一个 unicode 字符。
