The Info view doesn't show every command (scripts) which I actioned. Example open new file, reload file, import, export...
How to show them?
While the info window can be helpful, the list of commands it shows is not a complete list, some operators are intentionally filtered out because they don't relate to editing your data (panning the view for example or scrolling the text window).
One example is renaming an object, changing the name in the 3Dview properties sidebar or object properties shows in the info window but renaming in the outliner doesn't show.
With opening/reloading blend files, the info window is cleared after opening a blend file, so the open command would be cleared out. If you refer to opening text files in python, any task using basic python functions isn't going to show in the info window, a call to a bpy based function would need to be made for blender to echo it into the info window.
You can see most if not all of the missing actions by setting
bpy.app.debug_wm = True
Note that this will give a lot of extra entries, including zooming, typing in the console, scrolling up and down....
