Hi,
Sorry for not responding to this earlier. John, I'm especially sorry for
not trying your suggestion yet. So, I get varied results...
The first suggestion.
AddToFunc SwitchDecor
+ "I" Exec echo $0 > HOME/USER_WM_STYLE
+ "I" Restart HOME/bin/RunWM
I tried the first suggestion below, and it works for me, but I too was
afraid that it would be unreliable from the excerpt of the fvwm2 man page
which Dan mentioned.
>From the man page:
Note that this function doesn't wait for command to
complete, so things like:
Exec "echo AddToMenu ... > /tmp/file"
Read /tmp/file
won't work reliably.
>> In other places where I want to wait for an Exec to complete before moving on
>> I use PipeRead instead: so, one could try:
>>
>> AddToFunc SwitchDecor
>> + "I" PipeRead "echo $0 > HOME/USER_WM_STYLE"
>> + "I" Restart HOME/bin/RunWM
This suggestion works just fine for me. There is one interesting
difference from the first suggestion above. I pipe stdout and stderr to
~/.FVWM2-errors with
fvwm2 -cmd 'FvwmM4 fvwm2rc.m4' > ~/.FVWM2-errors 2>&1
The first suggestion causes the output of subsequent restarts to be
appended to the file. The second suggestion causes the file to be
overwritten. There is definitely something going on here, but I'll be
damned if I know what...
The third suggestion gives me an error for some unknown reason.
>> Or even:
>>
>> AddToFunc SwitchDecor
>> + "I" PipeRead "echo $0 > HOME/USER_WM_STYLE; echo Restart HOME/bin/
>> RunWM"
[FVWM][Done]: <<ERROR>> Call of '/home/tom/bin/RunWM' failed!!!!
(restarting 'fvwm2' instead)
Anyone have an idea why??? I guess it doesn't matter, the second
suggestion works. I should just use it and move on...

Now one last demonstration of my ignorance.
What does this mean?
PipeRead cmd option
Causes fvwm to read commands output from the pro-
gram named cmd. Useful for building up dynamic
menu entries based on a directories contents, for
example.
So this caused fvwm2 to read the result of the echo command and do nothing
with it?
PipeRead "echo $0 > HOME/USER_WM_STYLE"
