[SOLVED] Permission denied for dd command

I get permission denied for the following command when I tried
clone the .gz file. Even when the password given not seems doing.

arasu@lihome:~/Downloads$ sudo gunzip -c linux-mint.gz | dd of=/dev/sdb status=progress
dd: failed to open '/dev/sdb': Permission denied

if this actually works in theory.

Code:

sudo gunzip -c linux-mint.gz | dd of=/dev/sdb status=progress

then it is this

Code:

sudo gunzip -c linux-mint.gz | sudo dd of=/dev/sdb status=progress

just log in root

Code:

su
passwd
#gunzip -c linux-mint.gz | dd of=/dev/sdb status=progress

it might not even need to be entirely ran as root. Thererfore, just switch around what you've came up with.

Code:

gunzip -c linux-mint.gz | sudo dd of=/dev/sdb status=progress

unzip, or untar it s a user, and dd it as root

Hi,

looks like you are running gunzip as root, but dd as arasu.
