Linux services operation list

本文介绍如何使用'service'和'systemctl'命令来查看系统的非活动服务单元状态,包括'service–status-all'和'systemctllist-units-a–state=inactive'命令的具体用法。

使用 service :
service –status-all

使用 systemctl :
systemctl list-units -a –state=inactive

### Sumo on Linux System Configuration and Usage For configuring SUMO (Simulation of Urban Mobility) on a Linux system, the setup involves several key components that ensure proper installation and operation. The rerouting mechanism within SUMO can be configured using specific parameters such as `--device.rerouting.shortest-path-file <FILE>` which allows users to specify files containing shortest path data for dynamic route adjustments during simulations[^1]. To achieve ease of deployment and maintenance while ensuring scalability, it's important to follow best practices when setting up environments like those involving SUMO on Linux systems[^2]. This includes utilizing tools or services designed specifically for managing containerized applications efficiently. An interesting development related to infrastructure management is Virtual Kubelet—an open-source project implementing Kubernetes' kubelet interface—which could potentially simplify interactions between cloud-native platforms and simulation software by abstracting away underlying hardware details[^3]. When working with complex projects requiring extensive resources, leveraging existing solutions becomes crucial. A comprehensive list of freely available libraries and frameworks tailored towards robotics might prove invaluable not only for avoiding unnecessary duplication efforts but also enhancing productivity through readily accessible building blocks[^4]. ```bash # Example command line instructions for installing SUMO on Ubuntu/Debian-based distributions. sudo apt-get update && sudo apt-get install -y sumo sumo-tools sumo-doc ``` #### Basic Steps for Running SUMO Simulations: Ensure all dependencies are met before proceeding further into more advanced configurations. After successful installation, one may start exploring basic functionalities provided out-of-the-box via simple examples included in official documentation packages.
