i have this in script

Code:

#!/bin/bash
qemu-system-x86_64  -display none -vnc :1 -m 1G -smp 2   -enable-kvm -boot order=d  ~/vm/w7.img   
-cpu host   -usbdevice tablet   &&  vncviewer :1

i whant that vncdisplay open after qemu command. qemu command run i foreground so i need send it to bg and execute vnc.

i run script ./script & disown and then vnc display but howe make this in script so i dont need write ./script & disown just ./script

If Qemu runs as it should then you can try connecting the two with & instead of &&. The latter actually waits for the the first program to finish and then reacts based on the exit code. The former puts the first program into the background and then proceeds to run the second program.

Code:

sleep 5 && echo Hello

sleep 5 & echo Hello

See the bash manual down in the section on "Lists" for info on &&

yes i try with & but qemu still opens in foreground and then vnc whant open until qemu is in fg.

but when i run from terminal with & qemu goes to bg.
