Description Alexander Larsson 2018-09-20 07:41:01 UTC

This code in xdg-utils-common.in seems weird:
https://github.com/freedesktop/xdg-utils/blob/master/scripts/xdg-utils-common.in#L317

copied here:

 elif `dbus-send --print-reply --dest=org.freedesktop.DBus /org/freedesktop/DBus org.freedesktop.DBus.GetNameOwner string:org.gnome.SessionManager > /dev/null 2>&1` ; then DE=gnome;

Why are we running dbus-send and then executing its output, after having sent it to /dev/null.

It seems to get the right result:

$ if `false > /dev/null`; then echo YES; fi
$ if `true > /dev/null`; then echo YES; fi
YES

But, why?
