Command automatically execute after a copy paste

[kao_chen]

Binary package hint: gnome-terminal

If I do a copy paste on a command with the middle mouse button, it will be automatically validate in the gnome-terminal.
I just enter "history" in order to find an old command, I select it with a triple click, I copy it with the a middle click, the command is well paste, but it will be executed immediately.
In my case the command is wrong because I have paste the line number, I wanted to correct it before its executions.
And many times, if commands come with a copy/paste, they will be executed directly without warning.

You're copying a carriage return when you copy the command. You only need to double click it when you're copying text from the terminal. That third click is copying the whitespace at the end of the line, which is being interpreted as a carriage return when you paste it.

I think the "triple click" selects the entire line, with the carriage return placed at the end.
Gnome terminal probably displays each line with an hidden return at the end of each line.
With a copy/paste we can catch a carriage return practically anywhere.
The confusion comes from that in many case you will not know if you have one with you or not.

For example, in a html page, if you want to copy the command >echo "hello",
you will not copy a carriage return if the html code is like this :<div>echo "hello"</div>
but you will have it in this case: <div>echo "hello"
echo "I am a other text line"</div>
And in the both case, you'll see a end of line:

echo "hello"

echo "hello"
echo "I am a other text line"
