This simply isn't true. Read the docs.
find ./ | xargs perl -e'print "\n@ARGV"'
Should output one line with all of the arguements sent to perl.
You're perfectly right. I knew but just forgot it. Indeed this is the reason why at some time I got used to do stuff like
find . -type f | while read f; do stuff with $f; done
whenever I suspected that the argument list may have been too long. (Now I generally stick with -exec.)
Alternativly, just for the sake of putting this out there, this can be done without xargs
find ./ -exec perl -e'print "\n@ARGV" {} \;
But this would execute numerous copies of perl.
Indeed. It was me to point this out in the first place, as you can see in the post you're replying to.
But fear not for find hsa an altnative syntax!
find ./ -exec perl -e'print "\n@ARGV"' {} +
Which is also probably the best way to acomplish this task.
Interesting. This I authentically didn't know. Of course it's all out there in the manpages, I guess. But generally you learn "this kinda things" as people tell you about them...

    Well, it's in the recent man pages. ;-) Notice that James Youngman only added -exec {}+ support to GNU findutils on 15 January 2005. Not sure how commonly this handy (and more secure than xargs) find option is implemented on other Unices.
