I’m trying to use xargs to evaluate a mathematical expression.

Like:

echo "1234" | xargs -I{} echo $(({}+1))

But, for whatever reason, {} is always evaluated as "0" (while I can confirm those are integer).

Any hint? Maybe something else than xargs for the job here?

Thanks everyone. The solution was to call sh -c with '$(())', the single quote is the important bit I was missing!

#cli #bash #unix
