Ultimate List of Cheatsheets for a Sysadmin. ServersAustralia put together this list of cheat sheets containing everything from Apache to Drupal.

GeekFlares Cheatsheets List. Last weeks cheatsheets were extremely popular, so following the same theme we searched for an additional list and this is the best we could find. is a site collecting all the cheatsheets, all!Regular Expressions Cheat Sheet by DaveChild. Our Email Protection Service allows the use of regex to manage inbound and outbound mailflow. Our support team passed us this handy cheatsheet which includes symbols, ranges, grouping, assertions and some sample patterns to get you started.

Clean. I use this on my Mac to automatically move my desktop files into monthly folders each day. It saves a load of time because I just save all files to my desktop and they're then processed later that day. I appreciate a lot of people will want windows equivalent but I can't find anything, so please leave comments on the blog post or reply to this email and I'll include the best one next week.

trace32.exe | cmtrace.exe. "It's part of Microsofts SCCM suite from a few years ago, can open very large log files and display them as they update in real time.

The moment any of your IP addresses are found in a monitored RBL, RBLmon will send an immediate email notification to alert you, so you can get busy solving the problem.

WizTree helps you quickly find the files and folders using the most disk space on your hard drive. Rather than searching the drive and checking each file to determine size, WizTree gets its information straight from the NTFS Master File Table—which means it happens almost instantaneously. While this approach makes WizTree faster than any other type of program in this category, it only works with NTFS filesystems.

JuiceSSH is a simple, intuitive Terminal client for Android with SSH, Local Shell, Mosh, and Telnet support. Features a full-color Terminal with adjustable font size, keyboard including special characters, plugins, and key import/export/generation.

UNetbootin is a terrific, cross-platform utility for creating bootable live USB drives for Ubuntu and other Linux distributions without burning a CD. Thanks go to Gianks for this one.

CopyQ is a clipboard manager that adds some advanced editing and scripting capabilities. It monitors the system clipboard and saves text, HTML, images and more into customized tabs. From there, the saved content can be copied and pasted directly into any application. Clipboard history is easily searchable and can be filtered. Suggested by majkinetor.

Desktop Info provides a quick view of every kind of metric about your Windows system right on your desktop. The display looks like wallpaper but stays resident in memory and updates in real time. Gives you a quick way to monitor what any system is up to, while using very little memory and requiring almost nothing from the CPU. This one was recommended by mikedopp.

The dashboard runs on a Windows or Linux server, and it has agents for the Windows and Linux hosts you want to monitor. You can customize the dashboard to send notifications via email, Pushbullet, or NodePoint tickets whenever a client stops checking in or any of the configured checks fail. Configuration is retrieved from the dashboard by all agents in the form of templates, which are stored in the templates folder and can be customized for your needs. Thanks to mikedopp for this one!

I've used it on a boss's second pc where he wants it to logoff if he didn't remember to lock it after 15 mins of inactivity. Or at a very small medical provider where they have a dedicated scan station and the software doesn't play nice with fast user switching. It's an MIT License so it's good to go for a business environment as well."

Windows Sandbox is a lightweight desktop environment where you can run untrusted software safely. The software installed remains isolated in the sandbox so it cannot affect your host. Once it is closed, the software and associated files/state are permanently deleted. BlackEarl thought it was worth a mention because it was "included in 1903 update...

The server then provides a speakable, one-time-use password that you give the recipient. When they enter that password in their wormhole console, key exchange occurs and the download begins directly between your computers. rjohnson99 explains, "Magic Wormhole is sort of like JustBeamIt but is open-source and is built on Python. I use it a lot on Linux servers."

USBDeview lists all USB devices currently or previously connected to a computer. Displays details for each device—including name/description, type, serial number (for mass storage devices), date/time it was added, VendorID, ProductID, and more. Allows you to disable/enable USB devices, uninstall those that were previously used and disconnect the devices currently connected. Works on a remote computer when logged in as an admin. Thanks to DoTheEvolution for the suggestion.

"Passwords are like underwear. You shouldn't leave them out where people can see them. You should change them regularly. And you shouldn't loan them out to strangers." Source Unknown

"Give a person a fish and you feed them for a day; teach that person to use the Internet and they won't bother you for weeks."  An Unknown SysAdmin.

"If you want immediate feedback, always make changes in production" Source: Unknown.

"It's easy to forget that the ultimate goal of systems administration is to make systems, applications and services available to people who use them to get their jobs done. A good systems administrator must be able to communicate and get along well with others." Source article here

"A computer lets you make more mistakes faster than any invention in human history—with the possible exceptions of handguns and tequila." Mitch Ratcliffe



Are you being effective or just efficient? “Efficiency is doing things right; effectiveness is doing the right things.” This can make all the difference whether you're a SysAdmin, CTO or MSP. The way I think about this is essentially; are you being very organized (effective) working towards your specific goals (effective), or just being organized, feeling good about it, but achieving little. Read more about this in the "Effective Executive" by Peter Drucker.

Speed up your mouse pointer. Mine is at max. Try it. It's strange for the first hour, then you get used to it and get everything done faster. 

Windows Key + directional arrows will move and resize windows. (I.e., Windows Key + Up will maximize the window, windows key + left will snap it to the left of the screen and make it full height, WK + right will do the same but on the right side of the screen, WK + down will minimize the window.)

From greatshittywifi: "For Windows desktop cleanup I just wrote a simple batch script. Make yourself a folder called "sorted" or something and in it a subfolder for common file types "jpg", "png", "gif", etc. Then open up notepad, and paste this in:

move *.jpg "F:\sorted\jpg\"
move *.png "F:\sorted\png\"
move *.gif "F:\sorted\gif\"

Save it with a .bat extension, and voila! I'm sure you could modify this approach to detect file extensions, then mkdirs and move everything from a for loop if you want to go that far."

Quickly Find a MAC Address. Rather than going through network dialog windows or scrolling through long lists via ipconfig, simply open up a command prompt and type getmac. It’s quick, and easy, especially if you have multiple NIC interfaces.

Import PST files to Office 365 Exchange. For all of you Office 365 users, this is an option you need in your armory. 

Here's a simple trick for physically tracing unlabeled server-room cables: Slide a velcro loop or binder clip along the cable until you reach the other end. 

Use a mobile app barcode scanner to input IT hardware inventory. Just scan, then copy and paste instead of entering manually. You'll save a little time and eliminate the possibility of introducing typos.

For access to all of the sysinternals tools on any Windows box with internet, just Win+R and open \\\tools. It's a public SMB share with all of the tools that Microsoft hosts. Thanks to jedieaston for the tip.

BASH keyboard shortcut: 'Control + r' initiates a name/command lookup from the bash history. As you type, this 'reverse incremental search' will autocomplete with the most-recent match from your history.

Here are some helpful, lesser-known keyboard shortcuts for Windows, pulled together by sysadmin brother_bean.

Press the Windows Key + ...

  • Left or Right arrow—to snap the active window to half of the screen. (You can also do this by clicking and dragging your active window and smashing it into the left or right side of the screen.)
  • Up arrow—to maximize active window.
  • D—takes you to your desktop again to go back to your active window.
  • M—to minimize everything.
  • Shift + Left or Right arrow—to send your active window to the next monitor over, left or right respectively.

More keyboard shortcuts for Windows. Thanks for these go to RegularAlicorn.

  • Win + Ctrl + D—New virtual desktop
  • Win + Ctrl + (Left Arrow|Right Arrow)—Switch virtual desktop backward/forward
  • Ctrl + Shift + Enter (from the Start Menu)—Open focus program with admin privilege
  • Win + X (Win8+)—Really neat menu (RegularAlicorn's most-used shortcut) 
  • Win + Pause—Open the system settings
  • Win + L—Lock your computer
  • Ctrl + Win + Shift + B—Reset the graphics driver (may help avoid a restart for docking issues)
  • Win + Shift + S: Captures a user-selectable area of the screen to the clipboard (on Windows 10 Ver 1703+)
  • WIN + CTRL + F4: Close a virtual desktop

A shortcut for a 4-pane explorer in Windows without installing 3rd party software:

  • Win + E, win + left, up
  • Win + E, win + right, up
  • Win + E, win + left, down
  • Win + E, win + right, down

(Keep the win key down for the arrows, and no pauses.) Appreciation goes to ZAFJB for this one.

Our recent tip for a shortcut to get a 4-pane explorer in Windows, triggered this suggestion from SevaraB: "You can do that for an even larger grid of Windows by right-clicking the clock in the taskbar, and clicking 'Show windows side by side' to arrange them neatly. Did this for 4 rows of 6 windows when I had to have a quick 'n' dirty "video wall" of windows monitoring servers at our branches." ZAFJB adds that it actually works when you right-click "anywhere on the taskbar, except application icons or start button."

This tip comes courtesy of shipsass: "When I need to use Windows Explorer but I don't want to take my hands off the keyboard, I press Windows-E to launch Explorer and then Ctrl-L to jump to the address line and type my path. The Ctrl-L trick also works with any web browser, and it's an efficient way of talking less-technical people through instructions when 'browse to [location]' stumps them."

Clear browser history/cookies by pressing CTRL-SHIFT-DELETE on most major browsers. Thanks go to synapticpanda, who adds that this "saves me so much time when troubleshooting web apps where I am playing with the cache and such."

To rename a file with F2, while still editing the name of that file: Hit TAB to tab into the renaming of the next file. 
Thanks to abeeftaco for this one!

Alt-D is a reliable alternative to Ctrl-L for jumping to the address line in a browser.
Thanks for this one go to fencepost_ajm, who explains: "Ctrl-L comes from the browser side as a shortcut for Location, Alt-D from the Windows Explorer side for Directory."

Browser shortcut: When typing a URL that ends with dot com, Ctrl + Enter will place the ".com" and take you to the page.
Thanks to wpierre for this one!

This tip comes from anynonus, as something that daily that saves a few clicks:
"Running a program with ctrl + shift + enter from start menu will start it as administrator
(alt + y will select YES to run as admin) ... my user account is local admin [so] I don't feel like that is unsafe"

Building on our PowerShell resources, we received the following suggestion from halbaradkenafin: is "a way to learn PowerShell using PowerShell (and Pester). It's really cool and a bunch of folks have high praise for it (including a few teams within MSFT)."

Keyboard shortcut: 
If you already have an application open, hold ctrl + shift and middle click on the application in your task bar to open another instance as admin.
Thanks go to Polymira for this one.

Remote server advice: "When testing out network configuration changes, prior to restarting the networking service or rebooting, always create a cron job that will restore your original network configuration and then reboot/restart networking on the machine after 5 minutes. If your config worked, you have enough time to remove it. If it didn't, it will fix itself.
This is a beautifully simple solution that I learned from my old mentor at my very first job. I've held on to it for a long time."

Thanks go to FrigidNox for the tip!

MiataCory shares a shortcut that is "Something I use with RSAT all the time, but can be handy in other cases:
Shift + Right-click something to 'run as a different user'"
DevTechSolutions adds "To expand on this a bit, I use this trick to run Server Manager as my admin account, then run any RSAT tools from Server Manager and they are automatically run as the admin account. No need to run each tool as another user."

Credit for this helpful hint goes to AcceptEULA:
"I have\tools burnt into my brain. Blows a lot of folks minds when they realize you can access all that through File Explorer and you can map a drive to it."

"I'd add to the list of PS resources. It's a way to learn PowerShell using PowerShell (and Pester). It's really cool and a bunch of folks have high praise for it (including a few teams within MSFT)."
This is compliments of halbaradkenafin.

Use Win + shift + s instead of snipping tool. Thanks go to Nick_Lange_ for this one.

TheTajmaha suggested PSR.exe ( as a Built-in screenshot tool for Windows that is similar to Sharex. "You can almost rewrite all your windows documentation with PSR and it comes with windows. It screenshots the steps and writes it out for you!"

Next time it seems a machine is possessed by demons, take a look around to see if there's a magnet nearby. Magnetic fields can trigger weird behavior in laptops, like the screen suddenly going black or keyboard not functioning. As juskom95 explains, "Modern laptop screens have a magnetic sensor on the bezel to detect if the laptop lid is open or closed as opposed to the mechanical switch older models had. This wasn't noticed prior because laptops were thicker, now with the thinner laptops, the magnetic sensor of one laptop can trigger the laptop above [when they are stacked]. This is also the case for magnetic bracelets like those found on the smart watches and fitness devices."

The Cuckoo's Egg: Tracking a Spy Through the Maze of Computer Espionage. As one review says: "A great read. If you're a Unix sysadmin, like me, you will recognize and empathize with a lot of the concepts. If you've been doing sysadmin work for more than a decade, like myself, then you'll remember the old technologies as described in this book - the modems, the bulletin boards, the days before "ssh" ... If you're a new-school sysadmin, then you will be surprised to see a lot of things haven't changed in the world of Unix: telnet is still around, the "root" account is still around. The foundations of Unix were laid in the early 1970s. The events of this book took place in the 1980s. And many of the command line tools are still in use today."
