xterm in bash stops script from executing
I have the following script:
#!/bin/bash
xterm -e ' sh -c "$HOME/TEST/FirstAPP --test;" exec bash'
## script opens the xterm and stops until I press CTRL+C
while true; do
....
this question is related to this question
Why does the script stop at this place? I need to get the xterm called and running and then continue with the code having FirstApp running.
I used the gnome-terminal without problems.

Where exactly does it stop? And what does FirstApp do? Does it ever exit? How is the terminal when it is "stopped"? Does it display a prompt? Why are you runningexec bash?

it starts a process, that does not end, but sometimes fails, so that is why it need to be killed and restartd every hour.

But ifFirstAPPdoesn't end, how would anything else continue? Your command means "runFirstAPPand when that finishes, runexec bash". If that is not what you want, please edit and clarify what behavior you are expecting. You can also ping me in chat if you want and we can see if we can sort it out.

If you want your script to run a command and then continue executing, you need to tun the command in the background (&, see https://unix.stackexchange.com/a/159514/22222). So, change your script to:
#!/bin/bash
xterm -e 'sh -c "$HOME/TEST/FirstAPP --test;"' &
## script opens the xterm and stops until I press CTRL+C
while true; do
....
That will launch the xterm command in the background, keeping the terminal open and FirstAPP running, and will then continue onto the other lines of your script.
The reason it worked with gnome-terminal is because when you run gnome-terminal, it apparently forks itself and returns control to the shell you launched it from. You can see this with strace:
$ strace -e clone gnome-terminal
clone(child_stack=0x7fef6e44db30, flags=CLONE_VM|CLONE_FS|CLONE_FILES|CLONE_SIGHAND|CLONE_THREAD|CLONE_SYSVSEM|CLONE_SETTLS|CLONE_PARENT_SETTID|CLONE_CHILD_CLEARTID, parent_tidptr=0x7fef6e44e9d0, tls=0x7fef6e44e700, child_tidptr=0x7fef6e44e9d0) = 9534

# unwatch_fast: "/org/gnome/terminal/legacy/" (active: 0, establishing: 1)
# watch_established: "/org/gnome/terminal/legacy/" (establishing: 0)
+++ exited with 0 +++
Note the calls to clone which, as explained in man clone does:
clone() creates a new process, in a manner similar to fork(2).
So, unlike most programs, gnome-terminal will make a clone of itself when launched. The normal way of launching something and then continuing with something else is to use & to launch it in the background.

Where exactly does it stop? And what does FirstApp do? Does it ever exit? How is the terminal when it is "stopped"? Does it display a prompt? Why are you running
exec bash?– terdon♦

it starts a process, that does not end, but sometimes fails, so that is why it need to be killed and restartd every hour.

Have you tried running the terminal in the background?
