So I know if I type gnome-terminal or xterm, a new window will be popped out. Then I checked the man page for these two, nothing relevant found.

Then I noticed under Mac you can do it with the program open. But it seems under Linux it's not that trivial.

Does anyone have experience?

I would prefer to use the option -x that provides more reliable work than -e:

gnome-terminal -x bash -c "<my command or script>; exec bash"

• The option -x means --execute - the remainder of the command line inside the terminal.




• And our command is bash -c "<commands>". That means we execute a new bash shell, which should run some -c "<commands>".




• We have two separated (by semicolon ; == new line) <commands>.




• The first command <my command or script> will execute that we want.




• The second command exec bash has a meaning - remain open the current gnome-terminal window. There are another possible approaches to do that. In the current case the command exec will replace the current process image with a new process image - in other words it will 'kill' the current process and will execute a new (bash) under the current PID.

Update: The -x/-e syntax is now deprecated - Ubuntu 18.04. The new recommended way is :

gnome-terminal -- bash -c "<my command or script>; exec bash"

• If you want to reach the users home directory within the above command use the environment variable $HOME: bash -c "cd $HOME/; ..."
  

More examples of usage of this format:

• Open a new terminal and source scripts


• Launch gnome-terminal from SSH session to Desktop session


• Start Specific Terminal on Startup


• Crontab and C program that should be executed into a terminal window


• Xdotool does not minimize terminal window when using in Startup Application when pc boots?

gnome-terminal -e cmd will open a terminal window and run cmd within it.

You can simply do CTRLALTT and you will open a new terminal.

Try gnome-terminal -e "bash -c command;bash"

Another approach that will keep the window open is to use xterm:

xterm -hold -e cmd

The hold option keeps the window open.

and if i want to execute with a superuser, what i will have to add?

Because i'm trying something like:
gnome-terminal -x bash -c "sudo /usr/local/sbin/smequeue; exec bash"
