# SecureErase
- This Bash script, named "SecureErase," provides a secure method for permanently erasing data from specified external storage devices. The script prompts the user to enter the target devices, checks their existence, skips erasing the root device (/dev/sda) for safety, and securely wipes the selected devices using random data with a block size of 4 megabytes. Users with superuser privileges should execute the script, exercising caution as it irreversibly deletes data from the specified devices.
## code:
```bash
#!/bin/bash
# Function to check device existence
check_device() {
if [ ! -e "$1" ]; then
echo "Device $1 does not exist."
return 1
fi
}
# Function to securely erase a device
secure_erase() {
echo "Erasing $1..."
dd if=/dev/urandom of="$1" bs=4M status=progress
echo "Finished erasing $1."
}
# Check if the script is run with superuser privileges
if [ "$EUID" -ne 0 ]; then
echo "Please run this script as root (sudo)."
exit 1
fi
# Prompt the user for the target devices
read -p "Enter the target devices (e.g., /dev/sdX /dev/sdY): " target_devices
# Iterate through the space-separated list of target devices
for device in $target_devices; do
# Check if the device exists
check_device "$device" || continue
# Avoid erasing important devices
if [ "$device" == "/dev/sda" ]; then
echo "Skipping erasure of the root device (/dev/sda)."
continue
fi
# Overwrite with random data
secure_erase "$device"
done
```
## Installation:
