A common cracking technique is to find a buffer overflow in an suid root program, and then exploit the buffer overflow to snag an interactive shell.
常用的破坏技术是在suidroot程序中寻找缓冲区溢位，然后利用缓冲区溢位偷取交谈式shell。
Because of this, the program the user evoked when logging in has been rightfully called a shell, because it hides all the operating system's low-level calls.
由于上述原因，用户登录时调用的程序被恰当地称为shell，因为它隐藏了操作系统的所有底层调用。
You can download the different versions of the program as a tarball from Resources and view or run them in a separate shell, or view them in a separate browser window.
您可以从参考资料以tar压缩格式下载该程序的不同版本，并在单独的shell中查看或运行这些程序，或者在单独的浏览器窗口中查看。
For example, it includes a shell (the program that provides a command prompt and lets you run programs), a program to copy files, a program to delete files, and many other odds and ends.
例如，操作系统包含shell(shell程序提供命令提示符并且可以让你运行命令)、拷贝文件的程序、删除文件的程序还有其它这类东西。
It's not at all unusual to find that a single text line to a shell can do the same work as a hundred-line program.
您经常会发现在shell中一行简单的文本可以执行数百行程序才能实现的功能。
The bash shell contains two types of commands: builtins, which are internal, and external programs (or external filters and commands), which are typically self-contained binary program files.
bashshell包含两类命令：内部的内置命令和外部程序(或外部筛选器和命令，它们通常是自含的二进制程序文件)。
If you insist on calling the shell directly from a program, make sure that the environment is set up securely.
如果您坚持从程序中直接调用shell，那么就请确保环境的设置是安全的。
In this case, since the program really does have to run in a shell anyway, it even sort of makes sense to do it this way.
这种情况下，由于该程序实际上不必在shell中运行，所以这样做比较合理。
The -r sets the full path for the remote shell program to be used by GPFS.
r为gpfs使用的远程shell程序设置完整路径。

这是因为shell_exec允许您通过shell运行外部程序，然后以字符串的形式返回结果。
Shell viruses wrap themselves around a host program and don't modify the original program．Shell programs are easy to write，which is why about half of viruses are of this type．
