The .octaverc file is the octave [https://en.wikipedia.org/wiki/Configuration_file configuration file] on Linux. It has basically the same role as startup.m in Matlab | The .octaverc file is the octave [https://en.wikipedia.org/wiki/Configuration_file configuration file] on Linux that resides in the user's home directory (~). It has basically the same role as startup.m in Matlab - you might want to soft link startup.m and .octaverc to avoid duplication. Many basic settings can be put here. Further information is given in the [https://www.gnu.org/software/octave/doc/interpreter/Startup-Files.html documentation]. | ||
Some handy examples of configuration options are given below, as well and on the [[Tips_and_tricks|Tips and tricks]] page. | Some handy examples of configuration options are given below, as well and on the [[Tips_and_tricks|Tips and tricks]] page. | ||

The behaviour of the command line cursor in Octave is controlled by a separate codebase (readline), which has its own configuration file (.inputrc). Examples of useful entries in this file are given below and in ''??need a good reference for readline options??''. | |||
