There seems to be a conflict between these two statements: > should output every line that contains a search word "test" to STDOUT. and > If one goroutine finds it I can stop the other 7 from working.
If it is supposed to output EVERY line containing test, what is the logic that says you can stop the other goroutines? Is this because you have done something ahead of time that separates the input into lines, and so you know all the goroutines are operating on the same line? It looks, frankly, more like this is code to 'repeat STDIN on STDOUT if test is present anywhere in STDIN,' with no cognizance of lines at all. As long as that is what you are intending to do, rather than the described task, then you don't need to worry about stopping the other goroutines at all! "Program execution begins by initializing the main package and then invoking the function main. When that function invocation returns, the program exits. It does not wait for other (non-main) goroutines to complete." -- https://go.dev/ref/spec#Program_execution Simply exiting from your main when you have completed your read from STDIN and your write to STDOUT upon any of the goroutines returning a confirmation will end the program, whether other goroutines are still alive or not.
