How to post that a command is completed on screen

Hi All
My setup is

ubuntu14.04 64 bit.

One beaglebone black board.

I flash the sd card using this command

dd if=./bonexxxx.img of=/dev/sdx

command.
It takes some time say 15 minutes on my machine.

How can I post on screen a message such as

"command completed"

each time I run a command that takes more than 10 minutes.

# dd if=./bonexxxx.img of=/dev/sdx && echo "Command Completed"

do you mean something like this?

Code:

command && echo command completed

Added a screenshot. So in place of "Connected wired connection2" It should say "<Command> completed"
May be its a script related question.

If you have "zenity", "yad", "xmessage", or something similar, you can have a message pop up on your desktop.

Code:

dd if=./bonexxxx.img of=/dev/sdx && zenity --info
dd if=./bonexxxx.img of=/dev/sdx && zenity --notification --text="dd is done"

You could try using ; instead of &&. The && is dependent on the previous "successfully" completing (return code 0). Which would have no prompting if it failed. I tend more towards something like this:

Code:

$ date +%Y%m%d_%H:%M:%S; command; date +%Y%m%d_%H:%M:%S; beep

But it depends on which part of what has teeth (actually changes stuff). For something that depends on the previous thing making changes, most certainly use &&.
