Tell me how to wipe a disk from the command line on a Linux machine

Output

Here are several methods to wipe a disk from the command line in Linux: 1. Using `dd` command (basic method): 

1

5
# Overwrite with zeros
dd if=/dev/zero of=/dev/sdX bs=4M status=progress

# Overwrite with random data
dd if=/dev/urandom of=/dev/sdX bs=4M status=progress
Replace `sdX` with your target drive (e.g., sda, sdb) 2. Using `shred` (more secure, multiple passes): 
1
shred -v -n 3 -z /dev/sdX
-v : verbose -n 3 : number of passes -z : add final pass with zeros 3. Using `wipefs` (to remove filesystem signatures): 
1
wipefs -a /dev/sdX
4. Using `hdparm` (for SSDs with secure erase support): 
1
2
hdparm --security-set-pass password /dev/sdX
hdparm --security-erase password /dev/sdX
IMPORTANT SAFETY NOTES: - Double-check the device name before running any commands - Make sure you're wiping the correct drive - These operations are irreversible - Never wipe a mounted drive - You need root privileges (sudo) for these commands To check your drive name:

(-n 3: number of passes, -z: final pass with zeros, -v: verbose) 3. Using `wipefs` (to clear filesystem signatures):

IMPORTANT SAFETY NOTES: - Double-check the device name before executing - Make sure you're wiping the correct drive - These commands permanently destroy all data - Be extra careful with these commands as they're irreversible - Ensure the drive isn't mounted before wiping To check your drive name:

IMPORTANT SAFETY NOTES: - Double-check the device name to avoid wiping the wrong drive - Use `lsblk` or `fdisk -l` to identify the correct drive - Make sure the drive isn't mounted - These operations are irreversible - For SSDs, prefer manufacturer's secure erase tools when available Be extremely careful with these commands as they will permanently destroy all data on the target drive.

(Replace sdX with your target drive, like sda, sdb, etc.) 2. Using `shred` (more secure, multiple passes):

(-n 3 means 3 passes, -z adds a final pass with zeros, -v shows progress) 3. Using `wipefs` (to remove filesystem signatures):

IMPORTANT WARNINGS: - Always double-check the device name (sdX) before executing - These commands will permanently destroy all data - Make sure you're wiping the correct drive - You need root/sudo privileges - The drive shouldn't be mounted - For SSDs, consider using manufacturer-specific tools or ATA Secure Erase To check your drive names, use:
