Les opérateurs de comparaison

PowerShell supports comparison operators such as:

-ne (not equal to)
-lt (less than)
-le (less than or equal to)
-gt (greater than)
-ge (greater than or equal to)
-like (like—a wildcard comparison)
-notlike (not like—a wildcard comparison)
-contains (contains the specified value)
-notcontains (doesn't contain the specified value)

Les opérateurs de logiques

PowerShell supports several logical operators:

-and (The script block evaluates to True if the expressions on both sides of the logical operator evaluate to True.)
-or (The script block evaluates to True when one of the expressions on either side of the logical operator evaluates to True.)
-xor (The script block evaluates to True when one of the expressions on either side of the logical operator evaluates to True and the other expression evaluates to False.)
-not or ! (Negates, or reverses, the script element that follows it.)

Exemple :

Get-Command | Where-Object {($_.Name -like '*clear*') `
-and ($_.CommandType -eq 'cmdlet')}
