| import subprocess as sp | |
| import os | |
| file1 = open("C:\\Windows\\System32\\drivers\\etc\\hosts","r+"); | |
| fout = open("C:\\Windows\\System32\\drivers\\etc\\hosts2", "wt") | |
| newIP = sp.getoutput('wsl hostname -I') | |
| oldIP = "" | |
| index = 0 | |
| for line in file1: | |
| if index == 0: | |
| oldIP = line.split("#previp:",1)[1].strip() | |
| fout.write(line.replace(oldIP, newIP)) | |
| index = index + 1 | |
| print ("Replaced " + oldIP + " with " + newIP) | |
| file1.close() | |
| fout.close() | |
| if os.path.exists("C:\\Windows\\System32\\drivers\\etc\\hosts"): | |
| os.remove("C:\\Windows\\System32\\drivers\\etc\\hosts") | |
| else: | |
| print("The file does not exist") | |
| if os.path.exists("C:\\Windows\\System32\\drivers\\etc\\hosts2"): | |
| os.rename("C:\\Windows\\System32\\drivers\\etc\\hosts2", "C:\\Windows\\System32\\drivers\\etc\\hosts") | |
| else: | |
| print("The file does not exist") |
