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
You can just do
In the back of my mind I know this is there, but the
cat | greppattern is just muscle memory at this pointI'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
Just remember that if you aren't actually concatenating files,
catis always unnecessary.for me as well.
or if its a complex error cat log.txt|grep keyword1|grep keyword 2 and so on.
