I don't know what implementation of find you use, but the stock find on
CentOS 4 and 5 does not do any shell expansions, despite what the man
page might suggest. And why should it, find should be perfectly capable
to quote its results before injecting them back into a shell.
See for yourself:
$ mkdir testdir; cd testdir
$ mkdir foo; touch foo/bar; mkdir foo\ bar; mkdir \$PATH; mkdir \ \.\;rm\ \-rf\ foo\;; ls -1
$ find . -mindepth 1 -maxdepth 1 -type d -exec tar cz {} -f {}.tgz \;
$ ls foo
This is not a perl or shell script, it's a command that substitutes its
own results back into a shell. Afacit it does this safely (compare
printquoted.c). No user interaction in the form of the quoting of "{}"
required. If your version of find does I would consider that a bug ;) .
Regards,
Leonard.
