Shell – How to execute more than one command in a newly opened terminal

shell-scriptterminal

I have a script that I want to use to open new terminals and type commands in them. A command like

gnome-terminal

opens a new terminal.

Also, if I do

gnome-terminal -e myprogram1

it will execute myprogram1 in the newly opened terminal. But what if, after myprogram1 completes, I want to execute myprogram2? I cannot do something like

gnome-terminal -e myprogram2

because it will open a new terminal.

Is there a way to specify in the script that I want to execute both myprogram1 and myprogram 2 in the same new terminal? Or would I have to create a new script and do something like

gnome-terminal -e scriptToExecuteMyPrograms1And2

Best Answer

You can accomplish what you want like this:

$ gnome-terminal -e "bash -c '<cmd1>;<cmd2>;exec $SHELL'"

This will open up <cmd1>, when that's complete, it will open up <cmd2>, finally it will leave you at a command prompt exec $SHELL.

For example:

$ gnome-terminal -e "bash -c 'vim;vim;exec $SHELL'"

Runs vim, if I close the 1st vim, a 2nd vim is started. When the 2nd one closes I'm left at a terminal prompt.

Execute command in remote active terminal

There is a command line utility called ttyecho that can send a command to another terminal (tty/pts) and have the command executed.

sudo ttyecho -n /dev/pts/5 ls

See: Utility to Send Commands or Data to Other Terminals (tty/pts)

Also see: ttyecho source code on github.

Another interesting tty command is selector, a real-time interactive pattern matcher in console that updates the tty input buffer.

# selector examples
selector -v -x @ <(find . -maxdepth 2 -type d | awk '{print $0"@cd "$0}')
selector -v -x @ <(grep -E -o 'http[^ ]+' fileWithURLS)

See: selector - DYNAMIC SEARCH IN CONSOLE

Linux – open gnome terminal with several tabs and execute a few commands in every tab

This seems to work on my machine:

gnome-terminal --geometry=260x25-0+0 --tab -e "bash -c 'date; read -n1'" --tab -e "bash -c 'echo meow; read -n1' " --tab --tab

Please note, as soon as the processes executed by -e are done running, they will terminate. In this case, bash is loaded, runs whatever commands you pass to it, and immediately exists. I put in the read statements to wait for user input. This way those tabs won't close until you press a key, just so you can see it in this example. Without them, it would look as if only two tabs opened, because the other two would execute and close too quickly.
