Recursively list all files in a directory including files in symlink directories

Question

Suppose I have a directory /dir inside which there are 3 symlinks to other directories /dir/dir11, /dir/dir12, and /dir/dir13

Answer 1

I knew tree was an appropriate, but I didn't have tree installed. So, I got a pretty close alternate here

find ./ | sed -e 's/[^-][^\/]*\//--/g;s/--/ |-/'
