Which command is a common alias for Get-ChildItem when listing directory items?

• A. ps
• B. ls
• C. dir
• D. cat

Answer: (B)

In PowerShell, there are aliases that map to common commands to make life easier. Get-ChildItem lists the items in a directory, and the alias most people use for this action is ls, because it mirrors the Unix/Linux command for listing a directory and points directly to Get-ChildItem. This makes ls the natural shorthand when you want to view a directory’s contents. Other options refer to different tasks: ps is for processes, and cat shows file contents, so they don’t list directory items. While dir also maps to Get-ChildItem, ls is the widely recognized shorthand for listing in this context.
