Yes, sorry

C version. Maybe this logic should be built into GNU find as an option! $ find /etc/network | ./frangi-cheat /etc/network /if-post-down.d /wireless-tools /wpasupplicant /avahi-daemon /if-down.d /resolvconf /wpasupplicant /avahi-autoipd /interfaces.d /interfaces /if-pre-up.d /wireless-tools /wpasupplicant /ethtool /if-up.d /ntpdate /wpasupplicant /000resolvconf /openssh-server /ethtool /avahi-autoipd /slrn /avahi-daem…
I love your enthusiasm, and thanks for the code. But 1) the above only works with sorted input and 2) adding it to find that would be like adding '-v' to 'cat' which as we know is considered harmful. http://harmful.cat-v.org/cat-v/
All it is doing is hiding the redundancy with spaces to improve the human readability of find's output.
Here it is on the same data in breadth-first. Note the lack of any lexicographic sort: "interfaces" is flanked by "if-down.d" and "if-pre-up.d":
/etc/network
/if-post-down.d
/if-down.d
/interfaces.d
/interfaces
/if-pre-up.d
/if-up.d
/if-post-down.d/wireless-tools
/wpasupplicant
/avahi-daemon
/if-down.d/resolvconf
/wpasupplicant
/avahi-autoipd
/if-pre-up.d/wireless-tools
/wpasupplicant
/ethtool
/if-up.d/ntpdate
/wpasupplicant
/000resolvconf
/openssh-server
/ethtool
/avahi-autoipd
/slrn
/avahi-daemon
However, not munging the the output in that way and just tweaking the original output for readability has some advantages

- swap pointers to flip buffers instead of strcpy
- handle corner case of directory printed after contents (find -depth) by avoiding printing nothing but spaces, or nothing but spaces followed by a slash

2 directories, 2 filesAuthor here: Often I have to digest log files and lists of Azure resource names. I prefer to work with hierarchies of things, so I wrote this simple filter. Turns out to quite handy, especially when combined with awk and its friends.
(Really I just want `tree` on `s3`. There's `s3-tree` but that uses the entire bucket rather than a prefix)

Very cool tool! Any chance that you're going to add it to Homebrew?
