Re: how to pass arguments with space inside?

[lehe]

Actually in the bash script there is a command that passes "--options='-t 0
-v 0'" as argument to an executable. I just found if I double quote
--options='-t 0 -v 0' as argument to the bash script, then the '-t 0 -v 0' 
as a whole can be preserved until reaching the command invoking the
executable. However the '-t 0 -v 0' is not passed as a whole to the
executable,  but splitted by spaces again. 
This may sounds like the problem of calling the executable, however when
directly invoking the executable from terminal, either --options='-t 0 -v 0'
or --options="-t 0 -v 0" without quoting could be passed successfully as
argument.

Hope that I could explain my question clearly enough. Really appreciate your
advice!
