Meaning of the percentage sign (%) in PowerShell

In PowerShell code, we often see code like this:
PS C:\Users\test> Get-Childitem c:\ | % {$_. Name}

$_ here represents the cyclic variable.

Next, let's look at this percent sign (%), which is followed by a pair of curly braces ({}) and a variable expression in the curly brace.
What this code does is get all the subobjects in the c:\ directory, including all the files and folders. These objects are then output to the next statement.
The percent sign (%) is a circular statement, which is an alias for ForEach-Object. “% {$_. Name}" statement is to loop out all the object names.
