15.3. VisIt Run Commands (RC) File

VisIt supports a run commands or an rc file called the visitrc file which is typically located in ~/.visit. The visitrc file is a Python source code file that contains Python scripting commands that VisIt executes whenever the CLI is started either from the shell or from within the GUI through the Command Window.

The visitrc file is most often used to define Python functions associated with VisIt macros. However, users can use the file to run whatever Python code they wish during VisIt CLI startup. This could include opening a frequently used database, defining a set of frequently used expressions, etc. See the Python command-line interface manual for more information about the commands available in VisIt’s Python interface.
