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.🙏

regular expressions 101

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.

rubular

If you need help with regex, I use https://rubular.com/. This is just a nice regex editor that does highlighting and can show you what you are doing right/wrong when you are looking for an expression.

replit

You can even run it in the cloud via PythonAnywhere, Repl.it, and other sites (though I don't recommend throwing log files out on cloud services without confirmation from higher up, as "cloud" == "other people's computers", and that could be seen as a risk).

Jupyter

With Jupyter Notebooks, you can run a local server to write and execute code in a block-by-block manner, which is really great for doing log analysis (or any other data analysis or rapid prototyping). Don't worry if this point doesn't make sense yet, but it's a big thing when you get to it.
