PowerShell

A standard impementation using a For loop

for($n=99; $n -gt 0; $n--) {
   "$n bottles of beer on the wall"
   "$n bottles of beer"
   "Take one down, pass it around"
   [string]($n-1) + " bottles of beer on the wall"
   ""
}

My standard implementation using for loop

[int]$i = 99;
for($i=99; $i -gt 0; $i--) {
    write-host $i  " bottles of beer on the wall";
    write-host $i  " bottles of beer";
    write-host "Take one down, pass it around"
    write-host ($i-1) " bottles of beer on the wall"
    write-host ""
}

Consolidating the static text and using a Do...while loop

$n=99
do {
   "{0} bottles of beer on the wall`n{0} bottles of beer`nTake one down, pass it around`n{1} bottles of beer on the wall`n" -f $n, --$n
} while ($n -gt 0)

Consolidating the static text and using a Do...until loop

$n=99
do {
   "{0} bottles of beer on the wall`n{0} bottles of beer`nTake one down, pass it around`n{1} bottles of beer on the wall`n" -f $n, --$n
} until ($n -eq 0)

Consolidating the static text even more

$s = "{0} bottles of beer on the wall`n{0} bottles of beer`nTake one down, pass it around`n{1} bottles of beer on the wall`n"
$n=99
do { $s -f $n, --$n } while ($n -gt 0)
