as 命令是 GNU 组织推出的一款汇编语言编译器，它支持多种不同类型的处理器。
as 程序实际上是一个汇编程序家族。 如果您在一个体系结构上使用（或已经使用过）GNU 汇编程序，那么当您在另一个体系结构上使用它时，您应该找到一个非常相似的环境。 每个版本与其他版本有许多共同之处，包括目标文件格式，大多数汇编程序指令（通常称为伪操作）和汇编语法。

-ac：忽略失败条件； -ad：忽略调试指令； -ah：包括高级源； -al：包括装配； -am：包括宏扩展； -an：忽略形式处理； -as：包括符号； =file：设置列出文件的名字； --alternate：以交互宏模式开始； -f：跳过空白和注释预处理； -g：产生调试信息； -J：对于有符号溢出不显示警告信息； -L：在符号表中保留本地符号； -o：指定要生成的目标文件； --statistics：打印汇编所用的最大空间和总时间。
汇编文件：指定要汇编的源文件。
as 汇编文件，将输出写入 a.out：
as file.s
as 将输出组装到给定文件：
as file.s -o out.o
as 通过跳过空格和注释预处理，可以更快地生成输出。（仅应用于受信任的编译器）：
as -f file.s
as 包括目录列表的给定路径，以搜索 .include 指令中指定的文件：
as -I path/to/directory file.s
