Absolute path with ls?

Question

How can I make the ls command show a file's full path instead of just its filename? With all its options, there must be a way, right?

Answer 1

Here is one option for doing this.

ls -d $PWD/*

Answer 2

This is another way for individual files:

readlink -e filename

Answer 3

I usually use find:

find /dir -type -f -name "*"
