In `sh`, temporary files, FIFOs or file descriptors can be used instead. When the output of the command can be stored to a variable before entering the loop, here documents are a preferable alternative:
```sh
n=0
SUMMANDS="$(printf '%s\n%s\n%s\n%s\n%s\n%s\n%s\n%s\n%s\n%s\n' 1 2 3 4 5 6 7 8 9 10)"
SUMMANDS="$(printf '%s\n' 1 2 3 4 5 6 7 8 9 10)"
while read i; do n=$(( n + i )); done <<SUMMANDS_INPUT
$SUMMANDS
