The Or Statement in PowerShell

The logical operators connect expressions and statements in the PowerShell. It allows you to use a single expression for multiple conditions. The supported logical operators in the PowerShell are -and, -or, -xor, -not, and !.

For example, the below statement uses the -and operator and the -or operator to connect three conditions. The statement is true only when the value of $a is less than $b, and either $a is equal to 10 or $b is greater than 10.

($a -lt $b) -and (($a -eq 10)) -or ($b -gt 10)

-lt, -gt, and -eq are comparison operators in the PowerShell, which indicate less than, greater than, and equals respectively. The comparison operator allows you to compare values in the PowerShell. The PowerShell also includes other comparison operators such as -ne, -ge, -le, -like, -notlike, -match, -notmatch, -replace, -contains, etc.

This tutorial will teach you to use -or operator in the PowerShell.

Use the -or Operator for the Statement in the PowerShell

The -or operator, also known as logical OR in the PowerShell, returns the Boolean value True when either condition is true.

Consider, we have two variables $a=10 and $b=20. The following statement returns True because one condition is True: the value of $a is less than the value of $b.

($a -eq $b) -or ($a -lt $b)

Output:

True

When none of the conditions are true, it returns the False.

($a -eq $b) -or ($a -gt $b)

Output:

False
