The following editor will bring you a detailed discussion of Ubuntu PowerShell (a must-read tutorial for beginners). The editor thinks it’s pretty good, so I’ll share it with you now and give it as a reference. Let’s follow the editor and take a look.

As early as August last year, PowerShell began to be open source and cross-platform, but it has never been tried. It is called PowerShell Core.

Windows ignores case , so PowerShell on Windows is also ignored. However Linux is case sensitive. Therefore, PowerShell on Linux generally ignores case, but some special values ​​at the operating system level are case-sensitive (such as the names of some environment variables):

b) Alias

PowerShell on Windows has some Linux-type aliases, such as ls, cat, man, etc. However, these aliases no longer exist on Linux to prevent conflicts. For example, ls It is also an alias of Get-ChildItem in Windows PowerShell, but cannot be found in Linux PowerShell Core:
