I created a shell script that detects network interfages, and then for each interface it detects an IP address, mask, broadcast address, and then pings for all IP addresses for this network interface.
The script has execute permissions. Typically, the script will save the list of network interfaces (eth0 eth1 wlan0) in a file called "resultat", but when I run this script from a web page using the php shell_exec ( echo 'password for www-data user' | / usr/lib/cgi-bin/sudo -S global.sh bin/bash/" ), no output.
If I run the same script as the www-data user in the terminal, the result file will be correctly populated.
script:
