A directory listing command that produces a depth indented listing of files
Tree is a recursive directory listing command that produces a depth indented listing of files, which is colorized ala dircolors if the LS_COLORS environment variable is set and output is to tty. Tree has been ported and reported to work under the following operating systems: Linux, FreeBSD, OS X, Solaris, HP/UX, Cygwin, HP Nonstop and OS/2.
Note that if you just removed tree from APT distribution you will have to run the following command to regenerate GNU Bash's command search hash so that it will fall back to the command provided by the snap:
simply logout and re-login the user session will work.
This snap is maintained by 林博仁(Buo-ren, Lin), and is not endorsed or officially maintained by the upstream developers.
For versions of Ubuntu between 14.04 LTS (Trusty Tahr) and 15.10 (Wily Werewolf), as well as Ubuntu flavours that don’t include snap by default, snap can be installed from the Ubuntu Software Centre by searching for snapd.
Alternatively, snapd can be installed from the command line:
sudo apt update
sudo apt install snapd
Either log out and back in again, or restart your system, to ensure snap’s paths are updated correctly.
