如何在makefile中抑制回声？

Question

我在Makefile中有以下PHONY目标

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

当我运行目标时，它会显示正在执行的命令

提示＆GT; make install

输出

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

按我的意思输出

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

您可以在命令之前添加“@”来抑制回声

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