% ssh $hosts “/usr/bin/yes | /usr/sbin/pkgadd ”

Saying “y” to every question pkgadd might ask so you can do something useful while it installs software on $hosts.

Hint: first comment contained brackets so the “hosts” is missing

Thanks for the tip! this is going to dramatically cut down on the amount of code I have in my scripts. Great find…

so that’s one additional command and a wasted pipe to achieve what a command should natively be programmed to do. not sold yet, BB ! :)

anything that requires a repetitive entry of ‘y’, for example. I highly recommend trying the following:

% yes | /bin/rm -i *
