This outputs a structured view of files and folder of the directory you execute it in:
find . -print | sed -e 's;[^/]*/;|____;g;s;____|; |;g'
e.g.
. |____.git | |____branches | |____config | |____description | |____HEAD | |____hooks | | |____applypatch-msg.sample | | |____commit-msg.sample | | |____post-commit.sample | | |____post-receive.sample | | |____post-update.sample | | |____pre-applypatch.sample | | |____pre-commit.sample | | |____pre-rebase.sample | | |____prepare-commit-msg.sample | | |____update.sample | |____index | |____info | | |____exclude | |____objects | | |____info | | |____pack | |____refs | | |____heads | | |____tags |____CHANGELOG.txt |____COPYRIGHT.txt |____cron.php |____includes | |____actions.inc | |____batch.inc | |____bootstrap.inc | |____cache-install.inc | |____cache.inc | |____common.inc | |____database.inc | |____database.mysql-common.inc | |____database.mysql.inc | |____database.mysqli.inc | |____database.pgsql.inc | |____file.inc | |____form.inc | |____image.gd.inc | |____image.inc | |____install.inc | |____install.mysql.inc | |____install.mysqli.inc | |____install.pgsql.inc ...
ls -R does something similar, but structured considerably differently.
