What does "@" mean in makefile?
makefile
Solution
It disables printing the command line being executed. Any output from the command itself still appears. See this previous question or see this Makefile reference.
Problem
We offen use `@echo "do..."` to letting to print only `do...`. But who can tell me what is the mean of this condition ? ``` COUNT=$(shell ls | wc -l ) ``` Then ``` @COUNT=$( shell ls | grep abc | wc -l ) ``` What's the mean of the second?
