I want some specific websites to be extracted/grep before a string.
Example below:
Lets assume what is below is gibberish that i only want to extract website that is above SOLUTION NEEDED only! Not the other websites.
I only want to extract websites that can be found immediately above SOLUTION NEEDED
[36m[•] URL: abvfrt.com|LOAD
EXCEPTION: HTTPSConnectionPool(host='0.0.0.0', port=443): Read timed out. (read timeout=4)
[36m[•] URL: abc dot com |LOAD: xyz=345
EXCEPTION: HTTPSConnectionPool(host='0.0.0.0', port=443): Read timed out. (read timeout=4)
URL: Example dot com |: ABXCDRTTT
33m SOLUTION NEEDED
You can use grep -B n and -A n for showing you n number of lines Before or After the matched string.
In your case, something like
grep -B 1 "SOLUTION NEEDED" /path/to/file
Suggesting try this:
grep -B1 "SOLUTION NEEDED" long.log | grep -oP "(?<=^URL: )[^|]*"
grep -B1 "SOLUTION NEEDED" long.logExtract 1 line before each line matching "SOLUTION NEEDED"
grep -oP "(?<=^URL: )[^|]*"From extracted lines. Extract URL value.
