xargs is a great tool to take a lot of input and execute a lot of different commands based on that input. Sometimes though, if you are performing destructive or mutative actions with xargs you want to proceed more cautiosly.
> echo "banana apple orange" | tr ' ' '\n' | xargs -n1 echo "I like"
I like banana I like apple I like orange
But maybe I don’t like some of those things, please ask! Including the
p flag with xargs forces a prompt.
> echo "banana apple orange" | tr ' ' '\n' | xargs -p -n1 echo "I like" echo I like banana ?...n echo I like apple ?...y I like apple echo I like orange ?...n
Yep, I only like apples.Tweet
