systemd 学习

Linux systemd 学习总结

simple vs oneshot:

When you are deciding which service type to choose between simple and oneshot, here is some guidance:

Does your service need to complete before any follow-up services run? Use oneshot.
Do your follow-up services need to be running while this service does? Use simple.
Is this a long-running service? Probably use simple.
Do you need to run this service only at shutdown? Use oneshot.
Do you need to have multiple separate commands to run? Use oneshot.

新加一块 4T 硬盘挂载（非逻辑盘，没有 vgdisplay 的概念，就是简单的挂载到某个路径）

Ubuntu 设置 flameshot 快捷键

william 发布于 2023-07-31 收录于 Tools

使用 Win 键调出 keyboard 设置界面
在 Custom Shortcuts 点击添加 flameshot，其中 Name 可以自己写，然后在 Command 填写: /usr/bin/flameshot gui update: /usr/bin/flatpak run –branch=stable –arch=x86_64 –command=flameshot org.flameshot.Flameshot launcher
添加快捷键为 PrtScr
这样，就可以用键盘上面的截屏工具进行截图了
