After this paragraph in the *xargs* man page:

       Because Unix filenames can contain blanks
       and newlines, this default  behaviour  is
       often  problematic;  filenames containing
       blanks and/or  newlines  are  incorrectly
       processed  by *xargs*.  In these situations
       it is better to use the *-0* option,  which
       prevents such problems.   When using this
       option you will need to ensure  that  the
       program  which  produces  the  input  for
       *xargs* also uses a  null  character  as  a
       separator.   If  that program is GNU *find*
       for example, the *-print0* option does this
       for you.

Insert a new paragraph:

In the much more common case, Unix filenames
contain blank spaces but not newlines, and
furthermore, the input program has no *-0* option.
In that case, you can ensure correct operation
by inserting *tr \\n \\0* into the
pipeline just before *xargs -0*.  For example,

   *ls | grep* _regexp_ *| tr \\n \\0 | xargs -0 stat*

to stat all filenames matching _regexp_.
