Maybe I'm an outlier, but I really like the output of find(1), for hierarchical directory structures with mangeable numbers of files. In my interactive shell use, I tend to do 'find .' instead of 'ls -lr'.

You can put the full path in your bash prompt:

export PS1="\w\\$ "

I do this in my prompt (along with some other info).

If you do this, it's helpful to use ANSI color codes to make your prompt visually distinct from command output. But Terminal.app's ANSI support is broken, so, if you're on a Mac, you have to go to the trouble of downloading and configuring something else. I use iTerm2, which works great.

Here's an example. It's the same prompt as above, in a sort of cobalt blue. As you might guess, the part before the "\w\$ " is ANSIese for "be blue now" and the part after it is ANSIese for "stop being blue."

export PS1="\[\e[34;m\]\w\$ \[\e[0m\]
