如何抑制makefile中的回声? [英] How to suppress echos in makefile?

问题描述

我在Makefile中有以下PHONY目标

I have the following PHONY target in Makefile

install: 
        echo /usr/bin/shelldecrypt must be writable
        cp shelldecrypt /usr/bin

当我运行目标时，它会显示它正在执行的命令

When I run the target it displays the command it is executing

提示>进行安装

输出是

    echo /usr/bin/shelldecrypt must be writable 
    /usr/bin/shelldecrypt must be writable
    cp shelldecrypt /usr/bin

我会喜欢的输出

    /usr/bin/shelldecrypt must be writable
    cp shelldecrypt /usr/bin

推荐答案

您可以在命令之前添加"@"以抑制该回声

you could add "@" before your command to surpress that echo

install: 
        @echo /usr/bin/shelldecrypt must be writable
        cp shelldecrypt /usr/bin
