Pass a "Y" to dpkg-reconfigure?

Greetings!

Putting on my "dummy" hat here; as I'm sure this one is absolutely drop-dead simple

OK. Here's the commandline which I've been able to cobble together so far:

Code:

dpkg-reconfigure --frontend=readline --terse -plow unattended-upgrades

Now, being totally out of my element here, I tried:

Code:

Y | dpkg-reconfigure --frontend=readline --terse -plow unattended-upgrades

...with the expected results (an unmitigated mess on the terminal).

The real goal: To call dpkg-reconfigure -plow unattended-upgrades and simply have it exit with the desired "Yes" automagically passed in...

How might one go about making something like this tick over from the raw terminal?

Thanks a-bunch a-gain!

That will only send one "Y". If the pipelined process asks for confirmation more than once, it will hang.

@all:

Thanks for dropping by

I've now tried:

Code:

yes dpkg-reconfigure --frontend=readline --terse -plow unattended-upgrades

Code:

yes | dpkg-reconfigure --frontend=readline --terse -plow unattended-upgrades

Code:

echo "Y" | dpkg-reconfigure --frontend=readline --terse -plow unattended-upgrades

Code:

echo Y | dpkg-reconfigure --frontend=readline --terse -plow unattended-upgrades

Code:

echo Y > dpkg-reconfigure --frontend=readline --terse -plow unattended-upgrades

Code:

yes "Y" | dpkg-reconfigure --frontend=readline --terse -plow unattended-upgrades

Code:

yes Y | dpkg-reconfigure --frontend=readline --terse -plow unattended-upgrades

Code:

dpkg-reconfigure --frontend=readline --terse -plow unattended-upgrades yes

Code:

dpkg-reconfigure --frontend=readline --terse -plow unattended-upgrades yes y

...and even

Code:

yes --help

along with

Code:

man yes

and carbon powder-dipped cat's whiskers, and it still looks at me silly

???

Thanks again --

One more for the books:

Code:

dpkg-reconfigure --frontend=readline --terse -plow unattended-upgrades <<< $'y'

(still not working)
