answering vxdump by signals

[itai weisman]

hello everyone,
does anyone know how can i reply to vxdump question (like when a tape ends and replaced etc) by signals ? (kill -??)
can't find about it in the manual pages.
i found out (by guessing ) that kill -15 answers "NO" ...
if there is an alternative way to communitcate with backup procedure that runs on the background - i'll be glad to hear.
thanks ppl
Itai

If you want to run an interactive process (like vxdump) in the background you should think about using something like "expect".

[itai weisman]

what is that?

See http://hpux.connect.org.uk/hppd/hpux/Tcl/expect-5.43/

for details.

expect is scripting language used to automate interactive procedure in a non-interactive manner.

To say with example:

Automating telnet login:

telnet

will prompt for

Login:
Passwd:

It will expect for "Login" and "Passwd" strings and send our input to that.

Above link will give source area.

hth.

kill -15 is SIGTERM.This signal is used to politely request a program terminates. It is the default signal for kill(1) and killall(1). This signal can be caught in contrast to SIGKILL, and used to cleanup before exiting. The signals default action is to cause the program to terminate.
