Linux/Unix 下面很多的配置文件都包含rc这个词，比如：.bashrc、.vimrc，但一直不知道它们代表什么意思。
我一般喜欢靠记住单词的意思来识记各种命令、参数等。偏偏rc一直以来不清不楚，大概以为是Resource Configuration、Runtime Configuration之类的。
经查阅Google、StackOverflow，rc大概有这些意思和来源，我就不翻译了：
-
RunCom
[Unix: from runcom files on the CTSS system 1962-63, via the startup script /etc/rc] Script file containing startup instructions for an application program (or an entire operating system), usually a text file containing commands of the sort that might have been invoked manually once the system was running but are to be executed automatically each time the system starts up.
-
Run Commands
In the context of Unix-like systems, the term rc stands for the phrase "run commands". It is used for any file that contains startup information for a command. It is believed to have originated somewhere in 1965 from a runcom facility from the MIT Compatible Time-Sharing System (CTSS).

还有可以是以下一些来源及意思：
- run commands
- resource control
- run control
- runtime configuration
