A > simple "|| break" after the "cd .." will work, though. i know i asked this on irc, but i still a bit confused. the target would be to jump out from the loop and return 'false' if any of the items fails if i understand correctly then this is what Dscho proposes: $ for i in a b; do echo $i && false || break; done a $ echo $? 0 this jumps out from the loop but does not return false here is my version: $ for i in a b; do echo $i && false; done a b $ echo $? 1 this one detects the error but does not jump out from the loop. none of them is perfect, but at least my version fails as long as the last cycle fails (which is not problem as i think in most cases all or none of the cycles will fail) anyway, if you really want, i can change it, but i think it is not the right thing to do - VMiklos
