$ hostname -I

A Python script that uses hostname
I just used that command in a Python script, where I want to access the IP address of the local Linux system:
#!/usr/bin/python from subprocess import check_output ipAddr = check_output(["hostname", "-I"]) print 'IP Address: ' + ipAddr + "\n"
The script is actually much more complicated than that; I just wanted to show the parts relevant to getting the Linux IP address with the
