Hello everyone, I am your migrant worker brother.
All beginners who learn Linux systems know that in addition to simple system knowledge when getting started, secondly, the most important thing is to learn and understand the usage and application scenarios of Linux commands.
Therefore, everyone will also encounter such a situation, and we will search for information on commands that do not understand well. According to incomplete statistics, there are about 600+ common commands in the Linux system. It is too difficult to master them all at once, especially for a beginner, even more difficult.
In the background of the official account and technical exchange group, I often see that many people will encounter this kind of distress. If the command is not practiced or typed for a long time, it will soon be forgotten. When the application is applied, the help will be checked again. Ambiguous, it is impossible to find out the application of its use method and parameters.
Especially when multiple commands are required to complete a job, it is more difficult to write. Sometimes, even if someone in the group gives a relevant answer, it is still difficult for him to understand the meaning of it for a while? Why is it used in this way? Why do we need to use this parameter? A series of questions followed, but if you ask like this, it is inevitable that those who reply to you will be discouraged!
If there is a command interpreter tool at this time , it will be perfect!
So, today, the migrant worker gave everyone a practical and fun command learning artifact: kmdr.
