How do I learn grep in detail. I work at support and day to day need to have to deal with heavy logs. I have seen people playing with operators and other stuff to get the desired output. Someone was using Sed also. Please help.🙏

  RegExr is a HTML/JS based tool for creating, testing, and learning about Regular Expressions.

Regexr and Regex101 - Use these to test and debug your regex strings. Both sites have great breakdowns of what your string is doing, what it matches, and why, so it's great for tinkering with your search strings until you know you're going to match only what you want

  ripgrep recursively searches directories for a regex pattern while respecting your gitignore

I also recommend looking at ripgrep, which is faster than GNU grep.
