Accept input from a file

docker_load__input.md

I've always used this to load an image from a tar

docker load < image.tar

is same as:

docker load --input image.tar

Useful when I had to run something like:

cat docker-cache/docker-tags.txt | xargs -t -I % docker load < docker-cache/images/%

That fails because loading the file into stdin gets evaluated first before the value from xargs.

cat docker-cache/docker-tags.txt | xargs -t -I % docker load --input docker-cache/images/%
