Can I make a script wait for a key press when it has opened itself in a new terminal window?

I came across this line

if [ ! -t 0 ]; then x-terminal-emulator -e "$0"; exit 0; fi

which I can write at the top of a script and when clicking on the script file in nautilus, the script will open itself in a terminal window so that I can see the output.

Now there is the problem that this command

read -n1 -r -p "Press any key to continue..." key

in this case will not wait for a key press.

My guess is that x-terminal-emulator may be the reason, but I haven't found any other solution to double click a script file in Nautilus and get a new terminal window where the script will run.

Cannot reproduce. This code

#!/bin/bash
if [ ! -t 0 ]; then x-terminal-emulator -e "$0"; exit 0; fi
echo "new window"
read -n1 -r -p "Press any key to continue..." key
echo bye

when run with ./foo.sh </dev/null opens in a new terminal and waits for a key press.

You'll need to be more explicit about your code.

read -r -p "Press any key to continue..." key

waits for the Return key, no matter if #!/bin/bash has been used or not.

When

#!/bin/bash

is at the top of the script, -n1 will work and will wait for any key.
