Yes, that's why you need a wrapper around X2 that saves the commandline somewhere.
Like so:
# x2wrapper
/path-to-X2/X2 $* &
echo $! $* > /tmp/$!.commandline
Additionally - if you open a file from within the editor - you could run X2 with strace
and capture all calls to "open".

I just noticed that, while most editors display the path to the file
currently in view in the title bar, that information is not necessarily
complete because more than one file argument might have been passed on the
command line; also, any program switches are not displayed there.
If the program passes its PID to X, the xprop command can retrieve that, and
ps ef can be used to retrieve the original argument list. Unfortunately, X2
neither displays the current file's path nor passes its PID to X. :-(

Okay, I seem to have a working script (attached) that remembers the
X applications I'm concerned with (thank you, Nik); now, how do I tell
Trinity to execute it at shutdown time before it kills said applications?

Yes, but what to put in that wrapper? That's what my original
question was.
Ah, ok. I do not know X2, is it this one?
http://www.tangbu.com/x2main.shtml If yes, then there is one notable
things about the application (but correct me if I'm wrong): The X11
application "xx" does not set the X11 window title to the filename of the
file that's edited - which makes it an extremly hostile application and
difficult to find the filename in a general solution. The terminal
application "x" does neither, but you can get the filename from the
current instance if you parse the escape-sequence (<ESC>[H, then some
chatter and there comes the filename).
Anyway, the geometry of each window and the desktop where it runs on can
be found like this:
for ID in $(xwininfo -all -root|awk '/"X2 Editor Version 2.08.1"/ {print
$1}'); do echo $(xprop -id $ID|awk '/_NET_WM_DESKTOP/{print $3}') \
$(xwininfo -id $ID|awk '/geometry/ {print $2}'| tr -c '[0-9]'
' ')
\ $(/do/some/black/magic/to/get/filename/from/X2)
done > /some/place/to/store
Example /some/place/to/store:
2 484 559 58 0 /tmp/a.txt
4 100 100 100 100 /tmp/b.txt
To restore each window you basicly do something like this - nota bene: if
x2 were a nice application, you would not have to do this trickery to get
it's window id:
cat /some/place/to/store | while read DESKTOP W H X Y FILE; do
A=$(xwininfo -all -root|awk '/X2 Editor Version 2.08.1/ {print $1}')
/path/to/xx $FILE &
sleep 1
B=$(xwininfo -all -root|awk '/X2 Editor Version 2.08.1/ {print $1}')
ID=$(echo $A $B|tr ' ' '\n'|sort|uniq -u)
xdotool set_desktop_for_window $ID $DESKTOP
xdotool windowsize $ID $W $H
xdotool windowmove $ID $X $Y
done
I hope that get's you started. As I do not know how you use X2 (xx or x
...), I cannot give you a hint how to obtain the filename of a window
instance.
