With a slight modification, it will work in any POSIX shell, or even older Bourne-compatible shells as long as they have functions and <b>printf</b>:
<syntaxhighlight lang="sh">
quibble() {
printf '{'
while [ $# -gt 2 ]; do
printf '%s, ' "$1"
shift
done
if [ $# -gt 0 ]; then
printf '%s' "$1"
shift
fi
if [ $# -gt 0 ]; then
printf ' and %s' "$1"
fi
printf '%s\n' '}'
}</syntaxhighlight>
The test code is the same either way:
<syntaxhighlight lang="sh">
quibble
quibble ABC
