The difference between powershell and cmd

1. Resource occupation

First, let us take a look at the resource usage of Cmd and PowerShell. When we run Cmd, it only takes up less than 1M of memory, which is almost negligible.

When using PowerShell, it takes up about 20M of memory, which is almost 40 to 50 times different. It can be seen from here that if your computer is older and has lower performance, you can undoubtedly get higher fluency by using Cmd.

2. Interface

When we use Cmd, all characters are of the same color and syntax is not high. Bright.

However, if you are using PowerShell, the keywords will be highlighted and the error message will be displayed in red, which is really beautiful.

3. Typesetting

When we use Cmd to run some more complex and time-consuming commands, feel free to drag the command When you resize the window, the content in the window can still remain the same, neat and beautiful.

#However, if you use PowerShell to execute the same command, the situation is not optimistic. If you quickly drag the command line window during the execution of a command, the Chinese characters in the window will appear overlapping, seriously affecting the reading experience.

4. Command support level

Cmd can only support traditional Windows commands and cannot use commands in the .net library. , and commands under Linux cannot be used.

But PowerShell is much more powerful in this regard. It not only perfectly supports traditional Windows commands and commands in the .net library, but also supports some commonly used Linux commands.
