echo `cat multi_line_file` or echo $(cat multi_line_file`)
Or to avoid the fork & exec:
echo $(<multi_line_file)But you will end up with problems with the number of arguments on a command line if multi_line_file is too large.
How about:
cat multi_line_file | xargs
Note that the default command for xargs is echo
Or, to avoid a "useless use of cat" award (see http://partmaps.org/era/unix/award.html):
xargs < multi_line_file
Alas, that doesn't solve the problem with the excessive number/length of arguments either, because xargs will execute the echo multiple times if necessary to keep within the arg limits, potentially generating newlines in the output.
...Which is why I like the translate I proposed earlier:
tr "\012" " " <multi_line_file
tr -d "\012" < multi_line_file
is slightly more elegant. Of course this assumes the file is ASCII or similar.

But the OP said:
i want to have those lines joined to one line with spaces
