I am trying to invoke the crash utility through one of the linux startup scripts.
crash -i command.txt vmlinux vmcore

But this gives an error
/dev/tty no such device or address.

The tty is /dev/console



Once the linux box boots up and i login and use the same crash command as above it works correctly
The tty of the login shell is /dev/ttyS0

Any pointers on solving the error "/dev/tty no such device or address"



Thanks

I see what you're seeing running from /etc/rc.local,
where there's no /dev/tty file available to commands
run from startup scripts.

Try this -- which works for me:

crash vmlinux vmcore < command.txt

As a followup..

If I'm running crash, and now I want to 'source' a file of commands..
(i.e. like the shells "." command).. is there anyway to do this?

Sure -- the directions are part of "help input", and it's just a
matter of input redirection:

crash> < yourfile
...
