Product: Base System Version: 11.3-STABLE Hardware: Any OS: Any Status: New Severity: Affects Only Me Priority: --- Component: bin Assignee: bugs@FreeBSD.org Reporter: J.deBoynePollard-newsgroups@NTLWorld.COM Per https://unix.stackexchange.com/a/563986/5132 : 1. Run "su ; cat" 2. Press Control+Z (or whatever your susp character is) at the "Password:" prompt. 3. Notice that there is no terminal echo as `cat` is reading. Also: 1. Run "su ; stty echo ; fg" 2. Press Control+Z (or whatever your susp character is) at the "Password:" prompt. 3. Notice that your password is now echoed as it is entered into `su`. Use sh or compatible to replicate this, not the C shell, which does not exe= cute the commands after su. Contrast getpass(3), which at least handles SIGTSTP (even though it does no= t do so by also handling SIGCONT). --=20 You are receiving this mail because: You are the assignee for the bug.=
