Clears out port collisions for VMWare guests in Vagrant env.

#  Show the user what we're looking to remove from the network configs.

printf "\nWe've located the following entries matching the associated port argument. \n"
grep "add_nat_portfwd" /Library/Preferences/VMware\ Fusion/networking | grep $1
grep $1 /Library/Preferences/VMware\ Fusion/vmnet8/nat.conf


## 
#  Prompt the user for confirmation.

printf "\n"

printf "\n"

#  Get jiggy wit it.

  # MAX OSX sed commands
  # sed -i '' '/$1/d' /Library/Preferences/VMware\ Fusion/vmnet8/nat.conf
  # sed -i '' '/$1/d' /Library/Preferences/VMware\ Fusion/networking 

  # Linux sed commands
  sed -i.bak '/$1/d' /Library/Preferences/VMware\ Fusion/vmnet8/nat.conf
  sed -i.bak '/$1/d' /Library/Preferences/VMware\ Fusion/networking 

else

  printf "No files we hurt in the making of this script.\n"

fi

Usage:

sudo ./clear-net-ports.sh {faulty_port}

or 

sudo ./clear-net-ports.sh 2222

NOTE
This script is not yet 100% complete.
The sed commands do not parse command line arguments.

Further, it would be nice to be able to use multiple port arguments at the command line.

for MAC OSX i have success with this:
used ex instead sed, and add support for resetting VMware networking

Thx @catalinbostan !
I'll give that a shot. I'm usually working in OSX myself when I experience the issue.

@catalinbostan
Your script for OSX worked beautifully... Thx!

grep is hanging for me...i just get a usage: grep command just after We've located the following entries matching the associated port argument.
