No controlling tty

Postby sheran.vaz » Tue Dec 23, 2014 3:22 am


I created a QNX bootable CD. Started /bin/sh in rtinstall script. Shell starts but below messages are displayed.

"/bin/sh: No controlling tty (open /dev/tty: No such device or address)
/bin/sh: warning: won't have full job control"

What should be done, prior starting the shell?

Usually you start tinit rather than the shell. Tinit then invokes the shell when the user logs in. ... tinit.html

If you don't do things that way then when you exit your shell it will be gone forever (ie no new shell / login).
