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.
