How to run any command in another terminal window?

Example: I opened one terminal window and if I run command like apropos editor, then it run and out-puts on that window. But I want to run same command on another terminal window (new window) instead on present window from first terminal.

Further clarification:


I need suggest-command <command> that open new terminal window and run mentioned <command> in that (newly opened) window. (where suggest-command is example of suggestion of command.)

How to do that?

This might be what you search:

gnome-terminal -e "bash -c "!!; exec bash""

or (shortly):

gnome-terminal -x sh -c "!!; bash"

It opens gnome-terminal with your last command (!!) executed and it stays open with the command output in the shell, even with an interactive command like top or less...

In your case its:

gnome-terminal -e "bash -c "apropos editor; exec bash""

or

gnome-terminal -x sh -c "apropos editor; bash"

Start another instance of whatever terminal is it you want to run:

xterm -hold -e 'apropos editor' & 

Note the -hold. Most terminals will exit after running the command you feed them. There are already a dozen or so questions about this on the site:

• How can I make a script that opens terminal windows and executes commands in them?


• 
  How to run a script without closing the terminal?

An alternative to that is to use an application which needs to be exited. nano will stay open on its own. If you're just outputting to screen, you could pipe it into less:

xterm -e 'apropos editor | less' & 

That said, in your case (as the other two have said) it does seem easier that you just open another terminal and run your command.

Each terminal is even a program that you can launch as any other program,
with & to put in background, giving a list of arguments and so on.

Which terminal to use it depends first from the availability of the system that you are using (if they are installed or not), after from their peculiarity and then from your personal taste.

 konsole --hold -e "ls" & 
 xterm -hold -e "ls" & 
 gnome-terminal -e "ls" & ... 

Note the differences between -hold of xterm and --hold of konsole.

Each realization has different options that you have to check with the help.
Even the help can be invoked in different way.
You can find that man konsole doesn't function and so you have to ask directly to the executable with --help.

This is a list of terminal you can search on your system

You could use the -e option to gnome-terminal as follows:

gnome-terminal -e 'sh -c propose editor'

Here sh is the shell that gnome-terminal opens. Note that this will exit the terminal as soon as the command has terminated. Refer to the manual page for gnome-terminal for more.

1. Open two terminals;


2. Identifying each terminal with tty command;


3. Supposing they identified with /dev/pts/0 and /dev/pts/1;


4. In terminal pts/0 redirecting stdout to pts/1 with exec command: exec 1>/dev/pts/1
   


5. Now every command stdout output from pts/0 terminal is displaying in pts/1;


6. Redirecting back stdout with commad: exec 1>/dev/pts/0


7. Now pts/0 stdout working as before.

After Ubuntu 18.04 LTS, you may want to switch from -e to --, i.e. gnome-terminal -e to gnome-terminal -- because -e and -x are both deprecated.
