What does "rc" mean in dot files
In Unix world, RC stands for "Run Control".

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).
Reference: https://en.wikipedia.org/wiki/Run_commands
It looks like one of the following:
- run commands
- resource control
- run control
- runtime configuration
Also I've found a citation:
The ‘rc’ suffix goes back to Unix's grandparent, CTSS. It had a command-script feature called "runcom". Early Unixes used ‘rc’ for the name of the operating system's boot script, as a tribute to CTSS runcom.
Runtime Configuration normally if it's in the config directory. I think of them as resource files. If you see rc in file name this could be version i.e. Release Candidate.
Edit: No, I take it back officially... "run commands"
[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.
Thus, it would seem that the "rc" part stands for "runcom", which I believe can be expanded to "run commands". In fact, this is exactly what the file contains, commands that bash should run.
