Everyone knows that the Linux system has a lot of commands, and each command has a lot of usages. If you want to remember all the usages of all commands, I am afraid it is an impossible task.
In general, when we learn a command, we either directly search Baidu for its usage, or directly use the man command to view the lengthy help manual. Both of these can achieve our goal, but is there a simpler way?
The answer is a must! Today I recommend a fun and practical learning artifact-kmdr, which allows you to unlock Linux to learn new postures.
The biggest highlight of the kmdr tool is that if there is a long list of commands that you cannot understand its usage and meaning, it will be divided into modules to explain to you in detail! This function is really very useful, because we will inevitably see a variety of commands on the Internet or in books. If you do not understand it, it will always leave doubts. And this tool is like a teacher, telling you the usage and meaning of each part of the command one by one, let you see at a glance!
kmdr contains a lot of CLI command explanations, such as common ansible, conda, docker, git, go, kubectl, mongo, mysql, npm, ruby gems, vagrant, etc. Not only that, those bash built-in commands can do it for you Explain, very powerful!
No matter what field you are a programmer, kmdr can provide you with CLI command learning help to the maximum.
