摘要
作为Linux操作系统中最流行的Shell,Bash是绝大多数Linux工程师的必备技能。Bash既是命令解释器,也是脚本编程语言。它没有过于复杂的语法结构,相对于其他程序设计语言而言,Bash简单易学。但要写出健壮的Bash脚本程序并非易事,因为有很多需要编程者注意之处。通过实例,针对几处有助于提高Bash脚本健壮性的地方进行了讲解,对于Bash脚本编码工作者,无论是新人还是中高级用户都有非常好的借鉴意义。
As the most popular Shell in Linux OS,Bash is an essential skill for most Linux engineers.Bash is both a command interpreter and a scripting programming language.It does not have overly complex grammatical structures.Compared with other programming languages,Bash is simple and easy to learn.But it is not easy to write robust Bash scripts because there are many aspects that need to be paid attention to by programmers.Through examples,several points which can help to improve the robustness of Bash scripts are explained.This paper has very good reference value for Bash script coding workers,whether they are newcomers or intermediate and advanced users.
