Use the DD command to write the image file to the U disk under Linux

1, use df-h , check the current disk

[Email protected] ~/$DF-hfilesystem Size used Avail use%mounted on/DEV/SDA1 119G 79G 34G -% /None4.0K0  4.0K0%/sys/fs/Cgroupudev7.8G 12K7.8G1% /Devtmpfs1.6G1.1M  1.6G1% /Runnone5.0M     0  5.0M   0%/run/Locknone7.9G1.5M  7.9G1%/run/Shmnone 100M3.7M97M4%/run/user

2. After inserting the U-disk, use df -H to check.

[Email protected] ~/$DF-hfilesystem Size used Avail use%mounted on/DEV/SDA1 119G 79G 34G -% /None4.0K0  4.0K0%/sys/fs/Cgroupudev7.8G 12K7.8G1% /Devtmpfs1.6G1.1M  1.6G1% /Runnone5.0M     0  5.0M   0%/run/Locknone7.9G1.5M  7.9G1%/run/Shmnone 100M3.7M97M4%/run/User/dev/sdb12.0G0.0G2.0G0%/media/user/label

3, if your U disk is divided into multiple partitions, you need all umount, [email protected] ~ $ sudo umount /dev/sdb1

4. Use the DD command to write the image to the partition you just found, note: Do not write the partition number.

sudo DD if=/home/jack/ubuntu. 16.04. ISO of=/dev/sdb bs=4m

Tip: You can observe the operation at another terminal.

1 sudo kill -usr1 $ (pgrep ^DD)

Explain: Watch watch command run, kill command sends a signal,-USR1 is a DD-only signal, it receives the signal, it will show the progress of burning.

5. When the burn is finished, run:

Sync

The command is to check if the burn is complete, and when sync is over, you can safely unplug the U-disk.
