Get Raspberry Pi IP address

[RajshekharHoratti]

Hello, I am new to lua programming and i was trying to get my raspberry pi's ip address from lua i tried using

os.execute('ifconfig wlan0 | grep "inet\ addr" | cut -d: -f2 | cut -d" " -f1') but getting an error.

invalid escape sequence near ''ifconfig wlan0 | grep "inet'

So is there any other way to get ip address from lua.

What exactly are you trying to achieve? From the Lua runtime within info-beamer os.execute isn't available. My suggestion would be to either

• Write the IP address into a file using something like your command and then read that file with resource.load_file
• Export an environment variable INFOBEAMER_ENV_IP=1.2.3.4 and then use sys.get_env "IP" (documentation) in Lua.
