When I execute a subshell to obtain output of a command, the line breaks are lost.

For example:

filenames=$(grep 'foobar' /some/dir)
echo $filenames

Assuming there is more than 1 file in /some/dir that contains the string "foobar", those filenames will be printed in one long space-separated line instead of 1 filename per line.

I can't just use tr to convert the spaces back to line breaks since the filenames could have spaces in them anyway.

Is there a way to maintain the line breaks?
