How to use PowerShell break statement with the For loop?
To use the Break statement with the For loop, consider the below example.
Example
for($i=1; $i -le 10; $i++){
Write-Host "i = $i"
if($i -eq 5){break}
}Output
i = 1 i = 2 i = 3 i = 4 i = 5
Here, when the value of $i reaches to 5, For loop gets terminated.
To use the Break with the nested For loop.
- Inner For loop Break statement.
Example
for($i=1; $i -le 3; $i++){
for($j=1; $j -le 5; $j++){
Write-Host "i = $i"
Write-Host "j = $j`n"
if($j -eq 3){break}
}
}Output
i = 1 j = 1 i = 1 j = 2 i = 1 j = 3 i = 2 j = 1 i = 2 j = 2 i = 2 j = 3 i = 3 j = 1 i = 3 j = 2 i = 3 j = 3
Here, when the value of $j reaches 3, the only inner loop gets terminated but the outer loop execution still continues.
- Outer For loop Break Statement.
Example
for($i=1; $i -le 3; $i++){
for($j=1; $j -le 2; $j++){
Write-Host "i = $i"
Write-Host "j = $j`n"
}
if($i -eq 2){break}
}Output
i = 1 j = 1 i = 1 j = 2 i = 2 j = 1 i = 2 j = 2
In the above example, when the value of $i reaches to 2 it breaks outer and inner loop both.
