Except that you now have problems if the filename contains double quotes. Or backquotes. Or dollars. If you want to do the quoting yourself, better wrap the arguments in single quotes, after first escaping any single quotes:
find /path/ -size 0 |
perl -ple 's/\x27/\x27"\x27"\x27/g; "\x27$_\x27"' |
xargs -n ... rm
Note the use of
\x27 for single quote, lest it ends the argument to
perl.
Of course, if you're going to pipe into perl, there's not much point in calling xargs rm is there? Might as well do the removal from within perl:
find /path/ -size 0 | perl -nle 'unlink or warn "unlink $_: $!\n"'
Note that both pieces of code given above still fail on filenames containing newlines.
