To ignore errors in a command line, write a `-' at the beginning of the line's text (after the initial tab). The `-' is discarded before the command is passed to the shell for execution.
For example,
clean:
-rm -f *.o
This causes rm to continue even if it is unable to remove a file.
- 表示忽略命令执行的错误

在命令前加 @ 表示执行的时候,不输出命令本身的字符串,只输出结果
和 Batch 脚本是一样的
