$ a= read a <<< x # this creates a variable in the current shell $ declare -p a declare -- a="x" $ b= mapfile b <<< x # this doesn't $ declare -p b bash: declare: b: not found Other shells don't seem to agree on what should happen in this case, but it'd be nice to have a more consistent behavior. --- xoxo iza
