In Windows, it's possible to make files open at startup (using the default program for opening the file) by adding the files to the startup folder. However, in Ubuntu, it isn't possible to drag a file onto the list of startup applications so that it runs at startup. Is there another way to make a file open at startup, using the default program for opening that file?
I assume that you use Unity, however the process is quite similar with other Desktop Environments aswell.
Open the Dash and search for:
Click add and specify the command you'd like to use. You can then use two approaches, either you open the file by selecting the application you'd like to start with the file as an parameter, or you can use xdg-open as mentioned in this askubuntu-thread:
You may drag files to be executed at startup into ~/.config/autostart
However, they must be shortcuts (*.desktop files)
If you want to start scripts or documents,
put them in subfolders scripts and documents that you create inside autostart
and create the following shortcuts in autostart:
[Desktop Entry] Name=Scripts in 'scripts' folder Exec=/bin/bash -c 'for f in ~/.config/autostart/scripts/*; do eval "$f&"; done' Type=Application
[Desktop Entry] Name=Documents in 'documents' folder Exec=/bin/bash -c 'for f in ~/.config/autostart/documents/*; do eval "xdg-open $f&"; done' Type=Application
Ubuntu ought to be bright enough to allow any .desktop, script, executable or document file to be put in autostart and execute it appropriately.
