Enter openvpn private key password in a bash script -

i got function in bash script:

function start_vpn() { sudo ip netns exec frootvpn openvpn --config /etc/openvpn/frootvpn.conf &  while ! sudo ip netns exec frootvpn ip show dev tun0 up;     sleep .5 done } 

it fails because doesn't stop let me enter private key password. when enter sudo ip netns exec frootvpn openvpn --config /etc/openvpn/frootvpn.conf manually got private key prompt in script doesn't wait me enter :)

if mean sudo password can try

sudo sh -c 'ip netns exec frootvpn openvpn --config /etc/openvpn/frootvpn.conf &' 

---

for openvpn password try asking read fifo. echo password fifo. havent tried this.

mkfifo ~/myfifo sudo sh -c 'ip ... openvpn --askpass ~/myfifo ... &' 

then interactively, if dont want password echoed:

$ stty -echo; cat >~/myfifo; stty echo type password type control-d eof
