UNIX是一類功能強大的主流操作系統(tǒng)。本書從初學(xué)者的角度介紹了UNIX的系統(tǒng)概念及其命令的使用。闡述的內(nèi)容都是針對初學(xué)者完成日常工作所必需的各個方面，涉及UNIX系統(tǒng)的常用命令、UNIX文件系統(tǒng)、vi編輯器和Emacs編輯器、UNIX通信工具、shell命令和程序開發(fā)，以及一些更為深入的UNIX命令。書中還介紹了Linux操作系統(tǒng)以及Bourne Again Shell命令等。本書幫助讀者由淺入深、循序漸進地學(xué)習(xí)UNIX，形成清晰的概念，并且避免了直接羅列復(fù)雜的命令格式。
Amir Afzal，在喬治華盛頓大學(xué)獲得碩士及博士學(xué)位，美國弗吉尼亞州多所大學(xué)的教授，負責(zé)講授本科生、研究生的計算機和信息技術(shù)課程，在設(shè)計和開發(fā)實時計算機軟件系統(tǒng)方面積累了大量的實踐經(jīng)驗。本書是作者多年教學(xué)和實踐經(jīng)驗的總結(jié)。
