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主要的好處在于能夠利用大量的面向行的工具,特別是在過去20年中,在類unix操作系統(tǒng)下發(fā)展起來的那些工具。
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 在類unix系統(tǒng)上,需要設(shè)置共享目錄的“ sticky ”位;在sticky目錄中,文件只能由root或者文件的所有者解除鏈接或者重新命名。
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系統(tǒng)( x11 )為應(yīng)用程序以圖形方式進行顯示提供了資源,并且它是unix和類unix的機器上最常用的窗口系統(tǒng)。
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,在類unix系統(tǒng)中,如果多個用戶都可以向同一目錄添加文件,而且您計劃通過一個有特權(quán)的程序向該目錄添加文件,那么要確保為該目錄設(shè)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 實際上,競爭條件缺陷是軟件的更常見缺陷之一,此外,在類unix系統(tǒng)上, / tmp和/ var / tmp目錄經(jīng)常會被錯誤地使用,從而導(dǎo)致競爭條件。
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 在大部分類unix系統(tǒng)上,只在打開文件時才檢查權(quán)限,所以,攻擊者可以在權(quán)限位( permission bit )允許時打開文件,并使該文件一直處于打開狀態(tài),不管權(quán)限如何改變。
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 由于我所關(guān)心的是類unix系統(tǒng),我就不再深入地探討如何解決這個問題了,而且這也沒有什么意義,因為這只是一個例子,用來說明一種用于檢查的合法字符不足的情況。
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操作系統(tǒng)是一種免費的類unix操作系統(tǒng),它可以在所有的ibm硬件上運行:基于intel的xseries服務(wù)器, pseries unix服務(wù)器, iseries中級集成服務(wù)器,以及zseries高端大型機。
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的設(shè)計初衷是實現(xiàn)一個結(jié)構(gòu)簡單清晰,便于理解的、便于閱讀和修改源碼的類unix操作系統(tǒng),它的網(wǎng)絡(luò)服務(wù)器也僅僅是一個簡單的tcp ip協(xié)議棧在主機上的實現(xiàn)。
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文本實用程序包(包括用于microsoft windows的cygwin和用于mac os x的fink )是一個功能強大且靈活的工具集,它可以在linux和所有其它unix及類unix的操作系統(tǒng)下進行自動化的文本處理。
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.
