3- It has most of the basic functions you need for basic testing such as most of the common networking tools. 4- It is modular where the community have provided many different modules that can add a particular functionality the core is missing. ...
在用户空间,通常使用进程 这个术语,不过 Linux 实现并没有区分这两个概念(进程和线程)。内核通过 SCI 提供了一个应用程序编程接口(API)来创建一个新进程(fork、exec 或 Portable Operating System Interface [POSIX] 函数),停止进程(kill、exit),并在它们之间进行通信和同步(signal 或者 POSIX 机制)。 进程管理还...

1.块设备与字符设备 字符设备与块设备是并列的概念,这两类设备在Linux中的驱动结构差异较大,总体而言,块设备驱动比字符设备驱动要复杂的多,在I/O操作上也表现出极大的不同。缓冲,I/O调度、请求队列等都是与块设备驱动相关的概念。 2.块设备I/O操作特点 字符设备与块设备I/O操作的不同如下: (1) 块设备只...

A better way is to combine archival and compression functions with a pipeline. For example, this command pipeline unpacks .tar.gz: 上述方法不是调用压缩归档文件最快、最高效的方式,而且会浪费磁盘空间和内核I/O时间。 更好的方式是将归档和压缩功能结合起来使用管道。 例如,以下命令通过管道解包< file>...
5. Ignoring aliases and functions: By default, the “which” command ignores aliases and shell functions. If you want to include them in the search, you can use the “-a” option. For example: “` which -a ls “` This will show all locations where the “ls” command is found, incl...
