i agree with Dave and (Great :-) Mate, you need to tell a shell to do
it... so sh -c "your_command" should be ok for you.

by grepping the sources from the nightly snapshot (i had never done that
before, so i might be wrong) it looks like

g_spawn_command_line_sync() from glibc

is used in menu.c to run the commands associated to the menu entries. it
doesn't behave like a "system()", which would call (see man system) "sh
-c %s"... anyway it can look for the given commands in their path if
these are not specified.

as devhelp and e.g. also [1] suggest, there may be security concerns
anyway with depending on PATH...

what do you openbox-hackers think (about these paranoid fears of mine)?
:-)

well, going to quit talking about things i don't know now...

bye
