The following updated version

Create a python script to check if the link at the specified URL is valid


Same as in here

Create URL list to be checked

Grep as much as possible the character string that followshttps: // ...under the current directory. Save as input.txt.

grep -r "https://" * > test.txt
cat test.txt | sed -e 's/.*https//' | sed "s/^/http/g"  > test.txt
cat test2.txt | sed 's/>//g' | sed 's/"//g' | sed 's/)//g' | sed 's/;//g' | sed 's/]//g' | cut -d' ' -f 1 > input.txt 


Check if you can access the URL of input.txt.

$ python3

#Output result
#Can access → OK
#Inaccessible → Not Found
#* However, the grep result may not be as intended, so check it.


#-*- using:utf-8 -*-
import urllib.request, urllib.error

with open('out.txt', 'w') as txt:
    txt.write("chdck result\n")

def checkURL(url):
        f = urllib.request.urlopen(url)
        return True
        return False

if __name__ == '__main__':

    with open("./input.txt") as f:
        for url in f:
            # print(url, end='')
            ret = checkURL(url)
            if ret == True:
                result = "OK:"
                result = "NotFound:"

            ret_text = result + url
            #ret_text = ret_text.replace('\n', '')
            if ret != True:
                with open('out.txt', 'a') as txt:


Output the result OK/NG to the following

cat out.txt
