Script that formats a drive in a very specific way



I want to format a drive using a script in Ubuntu.



The required specs are:



Partition table: Master Boot Record



Partition Type: Linux



File System: Ext2



Screenshot of the desired result





My current problems:


sudo parted mklablel msdos



Doesn't change the Partition type to "Linux"


sudo mkfs.ext2



Doesn't work without existing filesystem



All help is appreciated! Thanks.





I think this question will be better received over on askubuntu.com since it's not programming related and is a little off topic here at SO.

Stack Overflow is a site for programming and development questions. This question appears to be off-topic because it is not about programming or development. See What topics can I ask about here in the Help Center. Perhaps Super User or Unix & Linux Stack Exchange would be a better place to ask.

Sure.


echo -ne 'onwn' | fdisk /dev/sdc # not needed on clean disc
echo -ne 'onnnnntn83nwn' | fdisk /dev/sdc
partprobe
mkfs.ext2 /dev/sdc1



The first line is there only to write clean dos partition table, so fdisk will not ask warning questions on the next run.
Then we create new clean dos parition table with on, create one partition that takes the whole disc with nnnn, change partition type to linux with tn83n and write that to disc with wn.
Then we need to rescan /dev/sdc to discover newly created partitions (fdisk should do that, but on some systems it fails).
Then we format /dev/sdc1 to ext2.
Script not tested. Use at your own risk.


on


nnnn


tn83n


wn





Thank you for your reply! Quick question: If i change "/dev/sdc" and "/dev/sdc1" to "/dev/sdd" and "/dev/sdd1" it changes the device, right?

Yes, see here for example. So don't make a typo ; )

PHP contact form sending but not receiving emails

PHP contact form sending but not receiving emails I have created a contact form using PHP to send the data. The form seems to send fine as there are no errors and success message appears, however I am not receving the emails into the designated inbox. I am using PHPMailer as I originally tried just using the php 'mail' command which I now understand is a bit hit and miss. I cannot see why I would not be receving the emails so I would be very grateful for any help that could be given. I'm quite new to PHP so please be patient with me :) <?php use PHPMailerPHPMailerPHPMailer; use PHPMailerPHPMailerException; $msg = ""; if (isset($_POST['submit'])) { require 'phpmailer/src/Exception.php'; require 'phpmailer/src/PHPMailer.php'; require 'phpmailer/src/SMTP.php'; function sendemail ($to, $from, $body) { $mail = new PHPMailer(true); $mail->setFrom($from); $mail->addAddress($to); $ma...

Do graphics cards have individual ID by which single devices can be distinguished?

Do graphics cards have individual ID by which single devices can be distinguished? I have several graphics cards of the same manufacturer and same model and I want to distinguish them not only by the pcie socket they reside in but by some individual value I can read from the hardware. Is there such value and if so what would it be called and how could I access it? Right now I'm using modern nvidia cards (10xx series) and nvidia inspector.but I'd prefer if there was any value that was also applicable to amd. I have programming and scripting knowledge. I am running Windows 10 1 Answer 1 This is a powershell example to pull information from video cards. The DeviceID is supposed to be unique but only if the manufacturer supports Windows Display Driver Model (WDDM). (I copied this directly from docs.microsoft.com) $strComputer = "." $colItems = get-wmiobject -class "Win32_VideoC...
