Powershell is a lot more bloated and slow than command shells on Unix and Unix-like operating systems. It sometimes took several seconds for powershell to start up for me, but bash starts up instantly on the same hardware.

Quick Tip: Everytime you are changing something in the registry, save a copy of everything at the start so when you mess up you will just load the backup instead of having to reset your windows.

[@Love_And_Relationship_Facts]

[@Househoppper]

Or you could just run a VM, make a .reg backup file in there, transfer it to your main pc, and run it

You can also use just one ampersand. Using one ampersand will run the second command after the first has finished no matter what; using two will run the second command only if the first command succeeded (didn't return an error code).

[@Jsheng007]

Great tips!

[@jimruby9657]

And there's one more - using double vertical bars (||) will execute the next command only if the previous command failed. This allows building an IF-THEN-ELSE in one command. Example: DIR BOB.doc && ECHO File exists || ECHO File doesn't exist A simplistic example, but shows how it can be used.

@@Architector_4 There are jobs for which a command prompt is unquestionably superior to a GUI. Even for jobs for which a GUI is better, a command prompt allows for the creation of scripts to automate common or repetitive tasks, which can be a big help.

@THIOJOE How to delete Visual snow with CMD?

[@bobcarn]

Nice tips! I did my computer teething with MS-DOS (version 1 or 2). But the "clip" command was really nice to learn! I hadn't known they added that into the command prompt. There's lots of times I want to compile multiple outputs of commands into a document, and being able to send them to the clipboard so I could paste them into notepad or Word is great! Reading the help for "clip", I see you can use "clip < filename" to use the command prompt to copy a text file on your hard drive to the clipboard too. Nice!

[@imanoob644]

🤦🏻‍♂️ my friend did the same thing

[@MrVampify]

A lot of these are standard sysadmin stuff. Just input/output redirection. > = takes stdout to whatever you put there. | = pipe just takes the output and inputs it to the next command. A lot of these work in linux as well depending on what shell you use. 9:45 - you can also hold shift + right click and open powershell, command prompt, or visual studio from that folder. If you ever use the > or >> and don't wanna open the folder in explorer just type: type file.txt In linux type is the same as cat it outputs the contents of the file into stdout (your output)

[@avi12]

6:35 Important: The "&&" is behaving exactly like in a programming language. In a programming language, this is the "and" operator. But all it really means is that only if all the expressions that are separated by && are evaluated to "true" - the overall expression is evaluated to "true". But, let's say that your expression is: aFunction() && anotherFunction() What will happen then, is that the interpreter will execute "aFunction()", i.e. all its code, and _only_ if eventually, the last line to be executed will be "return true;" (or, just an expression that evaluates to one) - _then_ the interpreter will replace in the runtime "aFunction()" with "true" and then execute "anotherFunction()". Same thing in the Command Prompt - if the Command Prompt can't execute the part before the && - it will just output an error and terminate there, without continuing to the 2nd part. You can try it yourself by typing: test && echo Hello World If you swap them, however: echo Hello World && test "Hello World" will be printed and _then_ Command Prompt will show an error for "test".

Instead of editing the registry, you can use the SETX command to set the prompt permanently, an example would be: SETX PROMPT $P$G , which would show the drive path followed by the greater than arrow

[@cerenademe9433]

Much better option.

[@techtechcy]

If you have the error below: ERROR: Invalid syntax. Default option is not allowed more than '2' time(s). Type "SETX /?" for usage. you can try replacing the spaces with $S. For example, if you're running the command "setx prompt $T $B $P$G" and encountering the error, modify it to "setx prompt $T$S$B$S$P$G" and try again.

In the enterprise @ThioJoe, can you deploy that first customized cmd via a gpo? Trying to figure out how to apply this where ever you login say.

[@YouVideo85]

Here's a couple of tricks I've found myself that has to do with the cd command. Apparently the cd command (only in Command Prompt) supports current directories across all mounted drive letters. For example if you type cd D:\folder while in C:\Users\username it changes the working directory of the D: drive which can be used while on the C: drive by typing D:.\ as the path on any command line program. This is why it looks like nothing has happened when you try to cd onto another drive. It only changes the working directory on that drive letter. You can also add /D after cd to change working drives and paths. So instead of typing D: then cd \folder, you get there with one command.

[@CamoFlash7_]

The 'prompt' and 'title' ones will be handy for trolling, thanks ThioJoe! Very cool!

[@hikaru-live]

Hint: the "/?" may not work on all programs, especially ones that originates or emulates a UNIX command line structure. If that is the case, try "-h", "--help" (double minus sign here) and "-?" which are common "/?" equivalents for UNIX command line.

[@franklittlefield6927]

ThioJoe: This may sound like a stupid question, but I couldn't find the folder for Command Processor. I typed in the search bar for all the folders you highlighted to get to yours...but without any luck. My question is this, where do I find it on Windows 10?

Could some folders been omitted going that route for obtaining the Windows 10 OS?

[@duncanandrews6727]

Regarding the Prompt, rather than editing the registry, you could also create a batch file (.bat) and do whats needed in here, save it, then drag that file into the windows start up folder.

[@Architector_4]

Will this actually work? Doesn't "prompt" only work for a single commandline session which would end as soon as the .bat ends?

[@markzajac]

That’s a great idea.

[@AAA-bo1uo]

Architector #4 You can set the autorun in the registery to open that batch file

[@freethinker1970]

Exactly I remember doing this before and you don't have to touch the registery

[@Architector_4]

+AA A Still doesn't exclude that the batch file is probably run in its own session which gets discarded as soon as the batch file ends. I'm not sure about that though. Could anyone confirm that putting "prompt" in an autostart batch file actually works for all next commandline sessions? _(Can't myself because I'm not on Windows.)_

There is an easier way to set the default prompt (no regedit needed). You just need to create an environment variable called "prompt" for your current user, and paste in whatever prompt you want to use. Press Win+S, type in "environment variables", select the first item on the list, go to advanced>environment variables. Press new... to add new variable In my case it looks like this: Variable | Value prompt | [$t]$s$e[92musername:$s$e[94m$p$e[0m$_λ$s If your terminal supports colors, then the username will be in green, and the path in blue

[@guilhermefigueiredo-234]
