Ubuntu – Where to find the legitimate key-values of nautilus accelerators

The value displayed is called by the function g_format_size_for_display of GLib. You have to edit the source code of nautilus to change this behaviour by just adding an %i to the output:

Step 1: Download source, install dependencies and open the file to edit

mkdir -p .p/nautilus && cd .p/nautilus
sudo apt-get build-dep nautilus
apt-get source nautilus && cd nautilus*
gedit src/file-manager/fm-properties-window.c

Step 2: Change the code

Now go to line 2338 (in Nautilus 2.30) and change with size %s to with size %s (%i Bytes). Do the same for totalling %s. Change it to totalling %s (%i Bytes) It should now look like this:

    text = g_strdup_printf (ngettext("%'d item, with size %s (%i Bytes)",
                     "%'d items, totalling %s (%i Bytes)",

Step 3: Compile

Now you can simply compile Nautilus like every other application

./configure --prefix=/usr
make
sudo make install
nautilus -q

Note that Nautilus will be overwritten whenever there will be an update to it through package management. This means you have to build and install it again manually.

There is also an alternative way by using an Nautilus script, but this would add another entry in the right click meny instead of having the value in the properties window.

If you want use the same sources from the installed version you must get it from the Ubuntu repository.

First, from the softwate center, software sources, you need to enable the "source code" sources.

Then you can use apt-get source, to get the source, and dpkg-buildpackage, to build the package.
