For me the easiest is on a sudo terminal (so I can omit the sudo part in the below commands), but if you’d do it “rather safe then sorry”, you can go from the fine-grained individual backup level:
sudo tmutil delete /Volumes/drive_name/Backups.backupdb/mac_name/YYYY-MM-DD-hhmmss
step by step
sudo tmutil delete /Volumes/drive_name/Backups.backupdb/mac_name
all the way back to
sudo tmutil delete /Volumes/drive_name/Backups.backupdb
Incidentally, the tmutil documentation is now regarded as legacy (I’m not sure why) so before it goes away, I’ve archived it:
[Archive.is] https://developer.apple.com/legacy/library/documentation/Darwin/Reference/ManPages/man8/tmutil.8.html
It’s not at http://developer.apple.com/library/mac/#documentation/Darwin/Reference/Manpages/man8/tmutil.8.html as for instance [WayBack] man tmutil … – Kristian Köhntopp – Google+ referred to a few years back.

With system account starting with underscore:
dscl . list /Users
Without underscore, so only regular accounts:
dscl . list /Users | grep -v ^_.*

There still is no ps xf on Mac OS X.
You need brew install pstree for that. Then you can excute pstree which gives you a treeview of the processes running.

I’m still amazed this is not in stock Mac OS X:
In Finder > Select a folder > Right click, we get a popup with an option to create a new folder:Is there a way to add menu item New Textfile for adding a new text file?

One way is to use Automator scripts, but: scripting…

Most sites explaining how to decompress an xz file mention you should use unxz from the xz utils toolbox.
Running unzx on Msc OS X requires the xz formula from homebrew:
$ brew install xz
==> Downloading https://homebrew.bintray.com/bottles/xz-5.2.2.mavericks.bottle.tar.gz
######################################################################## 100.0%
==> Pouring xz-5.2.2.mavericks.bottle.tar.gz
🍺 /usr/local/Cellar/xz/5.2.2: 91 files, 1.4M

It looks like when syncing folders between Mac OS X (MacOS X?) and Windows, many directories get empty Icon? files have a size of 0 bytes.
None of these directories had custom icons, so I’m inclined to remove them all from the Google Drive folder:
find . -name 'Icon*' -size 0 -print0 | xargs -0 rm
as [WayBack] Didier Trosset answered at [WayBack] How to delete many 0 byte files in linux? – Stack Overflow
Before I do that, I need to read these in more detail:

Great tool: [WayBack] htop – an interactive process viewer for Unix because it’s both interactive and supports a wide range of OSes: Linux, FreeBSD, OpenBSD and Mac OS X.
Thanks to Warren Postma who suggested it in his comment at [WayBack] 18 Useful Commands to Get Hardware Information on Linux – Linuxslaves.
Note that on OS X you get this warning after brew install htop :
htop requires root privileges to correctly display all running processes,
so you will need to run `sudo htop`.
You should be certain that you trust any software you grant root privileges.
On Linux you don’t get this message as there you have the /proc file system providing enough information as explained at [WayBack] osx – Why does htop on Mac OS X require root privileges to see data for all processes, but on Linux it runs without root – Super User.
A workaround (involving the setuid bit) is at [WayBack] Running htop on Mac OS X needs root. Why?! | Blog | JoeNyland.me or by running visudo ensuring you don’t need a password for it at [WayBack] osx – htop isn’t returning CPU or memory usage!? – Super User

Free and – unlike the also free [WayBack] dupeGuru – finds duplicate files – hasn’t crashed on my system yet or fails to add folders:
Read reviews, compare customer ratings, see screenshots, and learn more about Duplicate File Finder for files & folders. Download Duplicate File Finder for files & folders for Mac OS X 10.9 or later and enjoy it on your Mac.

cd /Volumes/Backup/Backups.backupdb/Joshua\ Priddle’s\ MacBook\ Pro/Latest/Macintosh\ HD/Users/priddle
tmutil restore -v secret_docs.txt ~/
Learned from [WayBack] Restoring files from OS X Time Machine with Terminal.app:
- do not use
cp as it will give you wrong permissions
- do use
tmutil
