Now that we're settled on WCE, would you agree that a=$(cmd-that-catches-sigint) should behave like (cmd-that-catches-sigint) (as in, not exit the shell as per WCE)? What about $PIPESTATUS? In: cmd-that-catches-sigint | cmd-that-does-not or cmd-that-does-not | cmd-that-catches-sigint Should we exit on SIGINT or leave that command run in background? Should pipefail have an influence on the behaviour? What about lastpipe? What about when using the wait builtin? Why should: cmd & wait "$!" be treated differently from cmd ? Because cmd's stdin is /dev/null and so is unlikely to be an interactive command? So we admit WCE is a kludge -- Stephane
