Damn no integrated advanced AI-driven solution that analyzes patterns and just predicts the errors? 🤨 (lemmy.sdf.org)

Please excuse my ignorance, but what is grep, what are the do's and dont's of logging and why are people here talking about having an entire team maintain some pipeline just to handle logs?

It's a command line tool which filters for all lines containing the query. So something like

cat log.txt | grep Error5

Would output only lines containing Error5

or if its a complex error cat log.txt|grep keyword1|grep keyword 2 and so on.

You can just do

grep Error5 log.txt

In the back of my mind I know this is there, but the cat | grep pattern is just muscle memory at this point

for me as well.

Just remember that if you aren't actually concatenating files, cat is always unnecessary.

I've been 'told off' so many times by the internet for my cat and grep combos that I still do it, then I remove the cat, it still works, and I feel better. shrug
