The progress of the DD command is displayed under Linux:

DD If=/dev/zero of=/tmp/zero.img bs=10m count=100000

To see the execution progress of the DD command above, you can use the following methods:

Example: Output dd progress every 5 seconds

Method One:

Watch-n 5 PKILL-USR1 ^dd$

Method Two:

Watch-n 5 KILLALL-USR1 DD

Method Three:

While KILLALL-USR1 DD; Do sleep 5; Done

Method Four:

while (PS auxww |grep "dd" |grep-v grep |awk ' {print $} ' |while read PID; Do KILL-USR1 $pid; Done); Do sleep 5; Done

The above four methods use three commands: Pkill, Killall, kill to the DD command to send SIGUSR1 information, the DD command process after receiving the signal to print their current progress.
