I was just thinking about the idea of allowing pacman to read from stdin for some operations, like -S. This would be great for people that want to upgrade from i686 to x86_64 with exactly the same software installed. That way they would just do (for example) pacman -Qi > packagelist, and on their new system do pacman -S < packagelist.

I've had this situation a few times, like when moving an old installation that uses i686 to newer hardware that's 64 bit capable.

Just a thought.
This task depends upon

Reason for closing:  Won't implement
Additional comments about closing:  Not a very common operation, and comment suggestion should handle majority of cases.

I'm not sure how answering questions will go if you redirect stdin, so that could be an issue.

"cat packagelist | xargs pacman -S" should produce the same results you are looking for, however.
