"@"代表什么?在makefile中意味着什么? [英] What does "@" mean in makefile?

问题描述

我们禁止使用@echo "do..."来仅打印do.... 但是谁能告诉我这种情况的含义呢?

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 )

然后

@COUNT=$( shell ls | grep abc | wc -l )

第二秒是什么意思?

推荐答案

它禁用打印正在执行的命令行.命令本身的任何输出仍会出现.请参阅此上一个问题，或者请参见此

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.
