I installed xdotool by running sudo apt-get install xdotool and throw xdotool key ctrl+alt+t command to open a new terminal window from the current one.But it was not working.
What was the command to open a new terminal window from the current gnome-terminal?
Just this command will do:
gnome-terminal
Normally if you want a command to open from the terminal and separate (so it returns to the prompt without having to close the opened program), you have to use something like this:
gnome-terminal & disown
However the parent terminal seems to detect that the same command is being used so you don't need to do that and gnome-terminal will suffice. This also seems to happen when running xfce4-terminal from Xfce's terminal, konsole from KDE's as well (doesn't seem to work when running xterm from xterm (see also xterm xterm) - Running konsole from Gnome/Unity & Xfce's terminal works as well, but for Xfce's terminal in gnome terminal you need xfce4-terminal & disown).
