Copy computer's IP address to clipboard

copy_my_computer_ip.sh

# When testing a rails website on my local development machine, I found my 
# Parallel's VM wouldn't load 0.0.0.0:3000, 127.0.0.1, or localhost:3000.  
#
# So I tried using my computers IP address and voila.  I thought I'd hone
# my bash chops a little and extract the IP address with the port number
# concatenated to it.  This command puts that on the clipboard so I can just
# paste it into IE so I could browser test. 
#
# NOTE: the pbcopy command is Mac specific.
#
# In my .profile:

alias cpip="ifconfig \                                                         
| grep en1 -A1 \                                                          
| grep -Eo 'inet\ [1-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}' \            
| cut -c 6- \                                                                  
| xargs -I {} echo {}:'3000' \                                                 
| pbcopy"

Thanks for the tips, code, and explanation. Learning more about bash scripting is at the top of my list so this is much appreciated!
