它可以在 grep 之后放一个断线吗？

Question

I have the code like this:

 scan-codes | grep -i '[!]\| url:\|started\|Aborted' | grep -v 'Effective\|style\|WARNING\|The version' 

Output:

        [+] Started: Sat Feb 19 05:21:00 2022
             | [!] 1 vulnerability identified:
             | [!] Title: Cookie Notice & Compliance for GDPR / CCPA < 2.1.2 - Admin+ Stored Cross-Site Scripting
    ############## need break line here ##############
             | [!] 1 vulnerability identified:
             | [!] Title: WPBakery Page Builder < 6.4.1 - Authenticated Stored Cross-Site Scripting (XSS)
############## need break line here ##############
            WARNING: Nokogiri was built against libxml version 2.9.10, but has dynamically loaded 2.9.12
        

And i want to put a break line (like \n) after grep. Its a scan, so i cant change the file.

Answer 1

Suggesting to use single awk script:

If matching combined 2 grep conditions than print current line + newline every 2nd line:

  awk '/\[!\]| url:|started|Aborted/ && !/Effective|style|WARNING|The version/ {ln++; print $0 (ln % 2) ? "\n": "";}'

Explanation

/\[:\]| url:|started|Aborted/ /\[:\]| url:|started|Aborted/ Positive line matching condition !/Effective|style|WARNING|The version/ Negative line matching condition

{ # For each line passing all conditions
   ln++; # count printed line
   newLineMaker = (ln % 2) ? "\n": ""; # New line marker any 2nd line
   print $0 newLineMaker; # print 
}
