UNIX是一类功能强大的主流操作系统。埃米尔·埃弗扎著的《UNIX初级教程(第5版英文版)/国外计算机科学教材系列》从初学者的角度介绍了UNIX的系统概念及其命令的使用。阐述的内容都是针对初学者完成日常工作所必需的各个方面，涉及UNIX系统的常用命令、UNIX文件系统、vi编辑器和Emacs编辑器、UNIX通信工具、shell命令和程序开发，以及一些更为深入的UNIX命令。书中还介绍了Linux操作系统以及Bourne Again Shell命令等。本书帮助读者由浅入深、循序渐进地学习UNIX，形成清晰的概念，并且避免了直接罗列复杂的命令格式。
本书可作为UNIX课程的教学用书或参考书，也可供使用UNIX的科技工作者阅读和参考。
