Every now and again, I need to start the Django development server, and have it viewable by other machines on my network, as described here:
http://docs.djangoproject.com/en/dev/ref/django-admin/#runserver
My machine’s IP address tends to change every now and again, so I’d like to have a little shell alias or something that spits out the manage.py command with my machine’s current IP address, maybe like this:
python manage.py runserver $(COMMAND TO FIND MY MACHINE’S IP ADDRESS GOES HERE):8000
ifconfig en0 | grep inet | grep -v inet6
Output of above is expected to be in the following form:
inet 192.168.111.1 netmask 0xffffff00 broadcast 192.168.111.255
Add an awk statement to print the second column to avoid using cut (awk is a pretty standard unix tool):
ifconfig en0 | grep inet | grep -v inet6 | awk '{print $2}'
I use the following to get the current IP when on a LAN where the first few numbers of the IP are always the same (replace 192.168.111 with your own numbers):
ifconfig | grep 192.168.111 | awk '{print $2}'
To get the ip of another machine that you know the name of, try (replace hostname and 192.168.111 with your own values):
ping -c 1 hostname | grep 192.168.11 | grep 'bytes from' | awk '{print $4}' | sed 's/://g'
