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
grep Error5 log.txtIn the back of my mind I know this is there, but the
cat | greppattern is just muscle memory at this pointfor me as well.
Just remember that if you aren’t actually concatenating files,
catis 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
or if its a complex error cat log.txt|grep keyword1|grep keyword 2 and so on.
