UNIX Shell and History Feature 1.The first task is to modify the main() function in Figure 3.36 so that a child process is forked and executes the command specified by the user. The next task is to modify the shell interface program so that it provides a history feature that allows the user to access the most recently entered commands. The user will be able to access up to 10 commands by using the feature. The commands will be consecutively numbered starting at 1, and the numbering will continue past 10. For example, if the user has entered 35 commands, the 10 most recent commands will be numbered 26 to 35. The user will be able to list the command history by entering the command history at the osh> prompt.

子进程 这个gem旨在成为一种简单可靠的解决方案，用于控制在Ruby / OS组合中在后台运行的外部程序。 该代码起源于 gem，但应证明它是独立的库很有用。 要求 Ruby 2.4以上版本，JRuby 9以上版本 Windows用户必须确保安装了ffi gem（ >= 1.0.11 ）才能使用ChildProcess。 用法 从ChildProcess.build返回的对象将实现ChildProcess::AbstractProcess 。 基本例子 process = ChildProcess . build ( "ruby" , "-e" , "sleep" ) # inherit stdout/stderr from parent... process . io . inherit! # ...or pass an IO process . io . stdout = Tempf
