This is a good use case for Expect, I think. Something like
```tcl
#!/usr/bin/env expect
spawn openvpn ...
expect Password
send -- "$password\r"
# any other prompts before the connection is made...
interact {
\x003 {
# user hit Ctrl+C
foreach mount {/mnt/a /mnt/b /mnt/c} {
puts "unmounting $mount"
exec umount $mount
}
send \x003 ;# send the Ctrl+C to openvpn
}
}
puts "bye"
```
