Hello and welcome to errortools articles. Today we will talk about some great and awesome tips and tricks for the command prompt. Commands which can make your life easier and your workday more pleasant.
That being said let's dive in right into muddy waters and swim out with new knowledge.
Tip 1: Read Motherboard information
There are a lot of reasons why you would like to read information from your motherboard, maybe you would like to upgrade your BIOS, perhaps you would like to know the serial number, maybe even the version number. Well, you can, type the following code into the command prompt and you will receive all information about your motherboard.
wmic baseboard get product,version,serialnumber,product
Tip 2: Copy command output to clipboard
Getting information from the command prompt to a word processor, into an email or any other medium can be somewhat troublesome, usually, people tend to screenshot or write from a command prompt into another destination, which could induce errors, and let's be honest, it is not practical. You can copy command output directly into the clipboard ready for pasting it anywhere with
| clip. So for example if you would like to paste the directory structure of your c drive command would look like:
dir c: | clip, now output would be placed into the clipboard ready to be pasted anywhere needed.
Tip 3: Erase data permanently
When you delete data on your hard drive, what really happens is that files are marked with a marker which marks that space for new data writing, but the data itself is still present and can be brought back. This sometimes could impose problems but if you would type:
cipher /w:c Windows will write random data over each marked file deleting it forever without means to be brought back.
Tip 4: Manage your IP address
If you would like to play with your IP address and do fancy stuff with it do the following:
ipconfig /release to release your IP address
ipconfig /renew to renew your IP address
ipconfig /flushdns to flush down DNS information and enjoy a new browsing start.
Tip 5: Check to see are packets reaching the desired location
You installed a new LAN printer, or a new switch, maybe you want to check if your new site is up and running. Use
ping destination in order to see if TCP packets are reaching desired information, you can use it with a specific address like
ping 192.168.1.1 or you can type a web address, for example,
ping google.com and see if a connection can be established.
Tip 6: Get information about a specific command
So you learned some command prompt commands, but you do not know all of their configuration or switches? No worries, just type command
/? to get a list of available switches for it. For example
ipconfig/? will write you a list of available switches for
ipconfig command.
Tip 7: Link and execute multiple commands one after another.
Let us say that for example, you would like to copy files into a different folder, then rename some and delete others and you need to do a couple of times. Instead of writing command after command once each one is finished link them with
&& and they will execute one after another.
Tip 8: Scan and repair files.
In order to scan files and repair broke or corrupted ones write in the command prompt:
sfc /scannow. Please know that this command can take a long time since it is solely dependant on the number of files, their size, and the power of the computer.
Tip 9: Manage and configure your computer energy
Command
powercfg will let you manage and see the power configuration of your computer. Just write
powercfg/? and see what you need and want to change or get information about.
Tip 10: Associate files with applications
Windows already has some file associations defined, and some applications take over some type of files but if you want to take control into your own hand use
assoc command. For example
assoc.txt= "APPLICATION NAME" will associate txt files with the provided application.
Tip 11: Hide files and folder.
Do you have some folder or file with information that you do not want to be seen when someone opens file explorer? Use
attrib +h <name of file> and hide file or
attrib +h /D <folder name> to hide folder.
Tip 12: Get a list of installed computer drivers
Want to know which drivers are installed in your system? Use
driverquery and take a look.
Tip 13: Find and locate shared folders
have you shared a folder but forgot which one and where? Do not bang your head on the wall, we have a simple solution for you. just type in command prompt
net share and see everything.
Tip 14: Run commands as an administrator
You do not have administrator privileges? Do you want to bypass common blockades?
runas /user:yourdomainadministrator command
That is all that we have for you today, I certainly hope you have found something useful here and that we have managed to teach you some valuable things.
The true cause is that there is no working Border Gateway Protocol (BGP) routes into Facebook's sites. BGP is the standardized exterior gateway protocol used to exchange routing and reachability information between the internet top-level autonomous systems (AS). Most people, indeed most network administrators, never need to deal with BGP.
Cloudflare VP Dane Knecht was the first to report the underlying BGP problem. This meant, as Kevin Beaumont, former Microsoft's Head of Security Operations Centre, tweeted,
"By not having BGP announcements for your DNS name servers, DNS falls apart = nobody can find you on the internet. Same with WhatsApp btw. Facebook has basically de-platformed themselves from their own platform."
Many people are very annoyed by this and with the fact that they cannot use their social media platforms but it seems that Facebook employees are in even bigger annoyance as it was reported that Facebook employees can't enter their buildings because their "smart" badges and doors were also disabled by this network failure. If true, Facebook's people literally can't enter the building to fix things.
Reddit user u/ramenporn, who claimed to be a Facebook employee working on bringing the social network back from the dead, reported, before he deleted his account and his messages:
"DNS for FB services has been affected and this is likely a symptom of the actual issue, and that's that BGP peering with Facebook peering routers has gone down, very likely due to a configuration change that went into effect shortly before the outages happened (started roughly 1540 UTC). There are people now trying to gain access to the peering routers to implement fixes, but the people with physical access is separate from the people with knowledge of how to actually authenticate to the systems and people who know what to actually do, so there is now a logistical challenge with getting all that knowledge unified. Part of this is also due to lower staffing in data centers due to pandemic measures."
Ramenporn also stated that it wasn't an attack, but a mistaken configuration change made via a web interface.
Both BGP and DNS are down, the "connection to the outside world is down, remote access to those tools don't exist anymore, so the emergency procedure is to gain physical access to the peering routers and do all the configuration locally."
Technicians on site don't know how to do that and senior network administrators aren't on site.
It seems that it will all be down for a couple of more hours before the issue is resolved. 
In today's world any professional, whatever be design, print, web design or similar is using one or more Adobe programs. Adobe has cemented itself as a must-have software for any kind of serious and even amateur work. Sadly in the latest Windows 11 adobe software in some instances can slow down your computer and put some hard load on the CPU. If you are one of these unfortunate users, keep reading because we have a few things you can do to solve this.
