In the enclosed example ( based on
http://unix.stackexchange.com/questions/303166/doesnt-work-the-bash-script-to-check-given-single-character-is-in-lower-case-or
), bash always echos Lowercase, whereas all dash, zsh, and ksh echo
Lowecase/Uppercase pairs as expected.
Repeat-By:
uplow:
read d
case $d in
[a-z]) echo "Character is in Lowercase";;
[A-Z]) echo "Character is in Uppercase";;
esac
test:
for sh in bash dash ksh zsh; do echo $sh; $sh uplow <<<x; $sh uplow<<<X
; echo ; done
