Step-by-step explanation:
The subject of this question is Computers and Technology. Specifically, it is about three different commands used to rename files or directories in a command-line environment.
Rename-Item (ren) is a command used in PowerShell to rename an item by specifying the current name and the desired new name. For example, 'Rename-Item C:\file.txt newfile.txt' will change the name of 'file.txt' to 'newfile.txt'.
rni is a shorthand alias for the 'Rename-Item' command in PowerShell. It can be used in the same way as 'Rename-Item' and is primarily used to save typing.
ren is a command used in the Windows command prompt (CMD) to rename files and directories. Its syntax is slightly different from the PowerShell commands, as it requires the current name followed by the new name. For example, 'ren file.txt newfile.txt' will rename 'file.txt' to 'newfile.txt'.
