I've read through the man pages for tree but I don't know if it is possible to have tree list only the filenames for all files that appear in any recursive search of a directory.
The closest I have gotten is: tree -i --noreport dir/ which might give me something like:
./lib
order
crossCount.js
rank
acyclic.js
./lib
order
crossCount.js
rank
acyclic.js
Where orderorder, liblib, and rankrank are directories that I do not want listed.
