Message-ID: <69f3c9f0-b91b-beb1-d36c-854bb4eb3ff3@iij.ad.jp> (raw)
Is this an intended behaviour?
% cat sum.sh
sum=0
while read n; do
sum=$((sum+n))
done
echo $sum
% seq 10 | zsh sum.sh
55
% yes ++sum | head -10 | zsh sum.sh
2046
% echo 'sum[$(echo Hello, world!>&2)]' | zsh sum.sh
Hello, world!
sum.sh:3: bad math expression: empty string
% zsh -c 'echo $ZSH_VERSION'
5.5.1
