After installing PiA client on ubuntu

PiA_Setup.py

# https://www.privateinternetaccess.com/pages/client-support/ubuntu-openvpn
# cd /etc/NetworkManager/system-connections
import fileinput, glob, os

def replace(file):
  for line in fileinput.input(file, inplace=True):
        print(line.rstrip().replace('password-flags=1', 'password-flags=0'))

your_pw = "YOUR PASSWORD"


def append(file):
  with open(file, "a") as myfile:
    myfile.write("\n[vpn-secrets]\npassword="+your_pw)

for file in glob.glob("PIA*"):
  replace(file)
  with open(file) as the_file:
  	if your_pw not in the_file.read():
  		append(file)

I was looking for a good way to bulk rename file extensions, and I recently found the most readable way to do it. They were .ovpn files, so I thought I'd add that here.

for f in glob.glob('*.ovpn'):
    f2 = f
    f2 = f2.replace('.ovpn', '.conf')
    os.rename(f, f2)

To take spaces out of filenames, you could use this same function and know what to put inside of f2.replace.

In Windows 10 I recently installed OpenVPN. As I needed to update the config files so I didn't have to enter the username and password each time, I wanted to do it the same way I did it on Linux. I figured I would just need to run Bash for Windows as the administrator to make it happen, and that worked. From the default directory, go to /mnt/c and then you can just navigate Windows as you would on Linux. Note that the updating of config files I'm talking about here is different than what I'm doing at the start of this gist.
