Have a look at how AJAX is used for a better feel of what kind of information you should be sending over. Keep in mind that with internet, possibly anyone could be seeing the information and at the same time possibly anyone could change the information. In this environment, you should not be sending code over such a channel. | |

| Feb 13, 2018 at 13:00 | comment | added | henriquehbr | I used nc -l $porta_cliente | sh as you said, but when the server receive the text, the following line if [ $? -eq 0 ]; then is automatically setting the $? to 0, so i can´t verify if the user pressed cancel on dialog, any workaround? | |
