Loops enable repeated execution of statements until certain conditions are met. There are currently two forms of loop statements: for loops, and while loops.

For loops take an array of elements as the input; looping through each statement in the block with each element in the array. If the input is a string, however, that string will automatically coerce into a newline-delimited array.

for element in @array
    echo $element
end

Sometimes you may need to exit from the loop before the looping is finished. This is achievable using the break keyword.

for element in {1...10}
    echo $element
    if test $element -eq 5
        break
    end
end

1
2
3
4

In other times, if you need to abort further execution of the current loop and skip to the next loop, the continue keyword serves that purpose.

for elem in {1...10}
    if test $((elem % 2)) -eq 1
        continue
    end
    echo $elem
end

10

While loops are useful when you need to repeat a block of statements endlessly until certain conditions are met. It works similarly to if statements, as it also executes a command and compares the exit status before executing each loop.

let value = 0
while test $value -lt 6
    echo $value
    let value += 1
end

0
1
2
3
4
5

Chunked iterations allow fetching multiple values at a time.

for foo bar bazz in {1..=10}
    echo $foo $bar $bazz
end

1 2 3
4 5 6
7 8 9
