!tree 命令可以运行最近一次敲的tree开头的命令: history 命令可以查看之前敲的命令: rm -r 命令可以批量删除目录,但是每次都会询问: 命令可以批量删除目录,因为加了f选项就不会进行询问了: rm -rfv 命令可以看到删除的过程,v这是v选项的作用。 转载于:https://blog.51cto.com/zero01/1972131...
Unix History This is a simplified diagram of unix history. There are numerous derivative systems not listed in this chart, maybe 10 times more! In the recent past, many electronic companies had their own unix releases. This diagram is only the tip of an iceberg, with a penguin on it ;-)...
History - shell会保留您键入的命令列表。如果需要重复命令,请使用光标键向上和向下滚动列表,或键入历史记录以获取以前命令的列表。 文件和进程(Files and processes) UNIX中的所有内容都是文件或进程。 进程是由唯一PID(进程标识符)标识的执行程序。 文件是数据的集合。它们由用户使用文本编辑器,运行编译器等创建。
To give as condensed a history lesson as possible, Unix was created by an assemblage of the finest minds in computer science at Bell Labs in 1970. In their task, they set themselves simple objectives. First, they wanted an OS that could smoothly run on whatever hardware they could find sin...

There have been four different implementations of signals in the history of UNIX. The Interix Software Development Kit (SDK) supports only the POSIX.1 set of signal semantics. However, the Interix SDK does support several different sets of signal-handling APIs, as follows:...

PROMPT_COMMAND="history -a" typeset -r PROMPT_COMMAND 这是由于bash shell实际上把历史写入到内存中,历史文件仅在shell会话结束时加以更新。这个命令会把上一个命令附加到磁盘上的历史文件。 最后,创建一个SIGDEBUG陷阱,将命令发送到系统日志(syslog)。VMware的ESXi借助自己版本的ash shell已经具有这样的功能。简...
