Thank you, actually i give all permision to www-data to be able to run this command from web page: shell_exec("sudo gdfs -o allow_other /var/www/html/gdfs.creds /media/pi/gdrives"); But, i could not execute it, fortunately i had a "B" plan as explain above(write .txt file if clicked, and check every second .txt file if there is changing, then run command from command line) I will take care your advice , and i will not give all permission to www-data. Maybe i can give some permission to www-data as your example

Actually i solved the problem, when user click the button i write this to .txt file. Then i am checking every second .txt file wheter there is a changing, if there is changing i am running my python script. But i would like to know your safer alternative and do you think my sudoers file unsafe ? if it is, can you give me example that trouble my system.

Thank you, should i change something in apache ?

Hello First of all thank you so much before i ask question, i have this line: var limit=obj.sky[0].satellites.length; if (limit>10) { limit=10 } i want to monitoring max 10 values but it can be less. i solved it with your help. Here what i do for (j= 1; j <=limit-1; j=j+1) { var value1 = str1.concat(obj.sky[0].satellites[j].PRN); } Because obj.sky[0].satellites[j] does not contain obj.sky[0].satellites[0].PRN that's why as you said, satellite[j] does not exist for the current value of j

Hello, var j; for (j= 1; j <=limit; j=j+1) { var value1 = str1.concat(obj.sky[0].satellites[j].PRN); } i do this and it is working in web page but if i do inspect element it says : Uncaught TypeError: Cannot read property 'PRN' of undefined at Object.success ((index):444) at i (VM16347 jquery-3.2.1.min.js:2) at Object.fireWith [as resolveWith] (VM16347 jquery-3.2.1.min.js:2) at A (VM16347 jquery-3.2.1.min.js:4) at XMLHttpRequest.<anonymous> (VM16347 jquery-3.2.1.min.js:4) i am not good at js can anyone tell me what is my fault ?

Thank you so much, this is what i search 👍
