Pyx s chief advantage is in leveraging the rich supply of line - oriented tools , especially under the unix - like operating systems that have emerged over the last 20 years Pyx主要的好处在于能够利用大量的面向行的工具,特别是在过去20年中,在类unix操作系统下发展起来的那些工具。
On unix - like systems , shared directories need to have the sticky bit set . in sticky directories , files can be unlinked or renamed only by root or the file owner 在类unix系统上,需要设置共享目录的“ sticky ”位;在sticky目录中,文件只能由root或者文件的所有者解除链接或者重新命名。
The x window system provides resources for applications to display themselves in a graphical manner , and is the most commonly used windowing system on unix and unix - like boxes X window系统( x11 )为应用程序以图形方式进行显示提供了资源,并且它是unix和类unix的机器上最常用的窗口系统。
But if multiple users can add files to a directory in a unix - like system , and you plan to add files to that directory from a privileged program , make sure that the 但是,在类unix系统中,如果多个用户都可以向同一目录添加文件,而且您计划通过一个有特权的程序向该目录添加文件,那么要确保为该目录设置“ sticky ”位。
In fact , a vulnerability to race conditions is one of the more common vulnerabilities in software , and on unix - like systems , the directories tmp and var tmp are often misused in a way that opens up race conditions 实际上,竞争条件缺陷是软件的更常见缺陷之一,此外,在类unix系统上, / tmp和/ var / tmp目录经常会被错误地使用,从而导致竞争条件。
On most unix - like systems , permissions are only checked on open , so an attacker could open the file while the permission bits said it was ok , and keep the file open with those permissions indefinitely 在大部分类unix系统上,只在打开文件时才检查权限,所以,攻击者可以在权限位( permission bit )允许时打开文件,并使该文件一直处于打开状态,不管权限如何改变。
Since i m concentrating on unix - like systems , i won t go into the details of how to deal with this problem , but it s worth noting , because this is an example where simply checking for legal characters isn t enough 由于我所关心的是类unix系统,我就不再深入地探讨如何解决这个问题了,而且这也没有什么意义,因为这只是一个例子,用来说明一种用于检查的合法字符不足的情况。
The linux operating system is a free unix - like operating system that runs on the entire range of ibm hardware : xseries intel - based servers , pseries unix servers , iseries mid - range integrated servers , and zseries high - end mainframes Linux操作系统是一种免费的类unix操作系统,它可以在所有的ibm硬件上运行:基于intel的xseries服务器, pseries unix服务器, iseries中级集成服务器,以及zseries高端大型机。
The original intention of the pagoda project is to implement a simple and concise unix - like operating system which can be easily to understand , read and modify . it ' s network server is just a tcp / ip protocols stack implemented for a host 由于pagoda的设计初衷是实现一个结构简单清晰,便于理解的、便于阅读和修改源码的类unix操作系统,它的网络服务器也仅仅是一个简单的tcp ip协议栈在主机上的实现。
The gnu text utilities package is a flexible and powerful set of tools for automated text processing under linux and all other unix and unix - like operating systems , including cygwin for microsoft windows and fink for mac os x Gnu文本实用程序包(包括用于microsoft windows的cygwin和用于mac os x的fink )是一个功能强大且灵活的工具集,它可以在linux和所有其它unix及类unix的操作系统下进行自动化的文本处理。
A Unix-like (sometimes referred to as UN*X or *nix) operating system is one that behaves in a manner similar to a Unix system, while not necessarily conforming to or being certified to any version of the Single UNIX Specification.
