I am trying to use a regular expression with grep command of Linux
(^\s*\*\s*\[ \][^\*]+?(\w*\:[^\*]+\d$)|([^\*]+[.]com[.]au$))
When I am trying it out at https://www.regextester.com with the contents of a file, I am getting the required result, i.e., the required fields are getting matched but when I am trying to use it as
grep '(^\s*\*\s*\[ \][^\*]+?(\w*\:[^\*]+\d$)|([^\*]+[.]com[.]au$))' file1
all it gives me is a null!
What’s the problem here?
did the trick 🙂
