How do you open command prompt on a PC when it's blocked?

How do you run ffmpeg in command prompt?
You run it the same way you do with a terminal shell in systems that are supported by FFMPEG. For syntax, the program will tell you if you use the --help option or check the man pages [Linux]/wiki/manual available online.
The general stuff you need to know is the -i option, the -b, -r, and -c, -vn, and -anoptions.
- The -i option specifies your input file(s). There fore you can place more than one.
- The -b and -r options specifies bitrate and sample rate. You add a :a or a :v after the -b option to specify which stream you want to specify the bitrate (-b:a for audio and -b:v for video). The value you specify is in bits/second (bitrate) and in hertz for sample rate. Of course current versions allow you to use letter multipliers as well (e.g. ffmpeg -i music.aac -c:a libmp3lame -b:a 320k music.mp3 converts a AAC file music.aac into a 320Kbps CBR [constant bitrate] MP3 file with an implementation of the LAME codec.
- The -c option is pretty much set up the same way as -b, -c:a for audio [older versions use -acodec] and -c:v for video [older versions use -vcodec]. But the -c option specifies which codec you wish to use (to find out what codecs you can use for your particular build, run ffmpeg --codecs).
- The last two are usually only useful for videos. The -anoption is generally used for cutting out the audio track for the given video input. Likewise, you can use the -vn option to extract the audio track from the video.
If you're having trouble, there is an okay graphical front-end for FFMPEG called WinFF.
How do you repeatedly run a code in command prompt?
You cannot repeatedly run a code in command prompt unless you create a batch script that will repeat the codes inside it. To create a script, you must open notepad. Type :A (colon A). Then below that code, type the codes you want to repeatedly run. Below the codes, write "goto A" (without quotes). Save this script as anything you like with a .bat extension. When you click the .bat script, it will read the code. On the last line of code, it will repeat any codes that is in between :A and goto A.
You can also change the "A" into anything you would like.
What is the command to run your programexe using the command prompt?

What is the primary dns in command prompt?
To get your network information from a command prompt, first you need to get your command prompt window open. You can do this from Xp and older by clicking the start button then typing cmd in the "run" box. In windows 7, click on the windows button then type cmd in the "search programs and files" box and the window will come up.
Once you have the command prompt window open, just type ipconfig in that window and hit enter. this will give you lots of useful network information such as your TCPIP address.
you can also type in ipconfig /? to get all of the possible "switches" you can use to get specific info.
How you move Curser in Command Prompt?
In most cases a command-line interface does not have a mouse cursor. With keyboard cursors, the only way is to type some text or press the Enter key (sometimes called Return key).
A C prompt is when you go to the Start Menu and go to Run or the search bar and enter Command. From there, a black screen will pop up with the drive letter and the current folder/path.
