Can I run cool-retro-term (or other visual shell programs) on WSL using Xming without requiring the original terminal to continue?

Question

I open up the WSL Ubuntu Bash, export DISPLAY=:0, and then fire up ./cool-retro-term; this works perfectly, but it by necessity crashes the CRT if I close the bash. Any tips on avoiding this?

Answer 1

Try nohup ./cool-retro-term &. That should do the trick. Nohup detaches the target process from the current bash terminal, and makes it immune to crashing when the terminal is closed. Note that I said closed, not Ctrl-C'ed. That's what the & is for. It moves the process to the background, so you don't have to worry about accidentally killing the process. After running this command, you can safely close CMD.
