[opensuse] BASH: Shorter way to do [[ $line == QUIT ]] || [[ $line == Quit ]] || [[ $line == quit ]] && break ?

Bash gurus, What is a shorter way to do multiple case insensitive tests on a string or variable that would accomplish this: [[ $line == QUIT ]] || [[ $line == Quit ]] || [[ $line == quit ]] && break Basically what I am looking for is some case insensitive way to test for quit or exit without having to define a test for each possible permutation without bringing in a big hammer like sed or the like. I am a bit confused on the test expansion but know things like $line == [Qq]uit won't work. I can do it in case: case $line in [Qq][Uu][Ii][Tt] ) break;; esac But that seems like a clunky use of case. Is there a better way? -- David C. Rankin, J.D.,P.E.
