PowerShell If statements need to be written in a particular syntax. Let’s look at some examples below.
Equals
In the example below, we test for equals. Note the notations -eq:
$a = 1
$b = 2
If ($a -eq $b)
{
Write-Output "Equal"
}
Else
{
Write-Output "Not Equal"
}
Greater Than
In the example below, we test for equals. Note the notations -gt:
$a = 1
$b = 2
If ($a -gt $b)
{
Write-Output "Greater than"
}
Else
{
Write-Output "Not greater than"
}
You can also use ge (greater than or equal to), lt, le etc.
Note the order can be switched.
Boolean
Let’s look at a true/false example below, which produces false:
$a = $false
If ($true -eq $a)
{
Write-Output "true"
}
Else
{
Write-Output "false"
}
