In a world bursting with new tools and diverse development environments, it’s practically a necessity for any developer or engineer to learn some basic sysadmin commands. Specific commands and packages can help developers organize, troubleshoot, and optimize their applications and—when things go wrong—provide valuable triage information to operators and sysadmins.
Whether you are a new developer or want to manage your own application, the following 20 basic sysadmin commands can help you better understand your applications. They can also help you describe problems to sysadmins troubleshooting why an application might work locally but not on a remote host. These commands apply to Linux development environments, containers, virtual machines (VMs), and bare metal.
