I am trying to find all non readable 'ACL-wise' in a subdirectory owned by another user www-data, and that on a 'FreeBSD' server. This server prevents me from using the command find . ! -readable



How could I find all the non-readable (by the current user) files in a directory?






find posix

You can always do:



find . -exec sh -c '
 for file do
 [ -r "$file" ] || printf "%sn" "$file"
 done' sh +


To list the files you don't have read permission for.



Note that for symlinks, that checks the target of the symlink.



It also obviously won't report files in directories you don't have read permission to (which may contain files you have read access to (provided you have search access to the directory) and/or files you don't have read access to).



On FreeBSD, you should also be able to do:



find . -print0 | perl -Mfiletest=access -l -0ne 'print unless -r'


Or



sudo find . -print0 | perl -Mfiletest=access -l -0ne 'print unless -r'


To also list the files in the directories you don't have read access to.



(neither sudo, -print0 nor perl are specified by POSIX).

            One-line joke

            A one-liner is a joke that is delivered in a single line. A good one-liner is said to be pithy - concise and meaningful. [1] Comedians and actors use this comedic method as part of their act, e.g. Jimmy Carr, Tommy Cooper, Rodney Dangerfield, Norm Macdonald, Ken Dodd, Stewart Francis, Zach Galifianakis, Mitch Hedberg, Anthony Jeselnik, Milton Jones, Shappi Khorsandi, Jay London, Mark Linn-Baker, Demetri Martin, Groucho Marx, Dan Mintz, Emo Philips, Tim Vine, Steven Wright and Henny Youngman and Arnold Schwarzenegger. [ citation needed ] Many fictional characters are also known to deliver one-liners, including James Bond, who usually includes pithy and laconic quips after disposing of a villain. [ citation needed ] Examples "A baby seal walks into a club." "A dyslexic man walks into a bra." (Anonymous) "There are three types of people, those who can count and those who can't." "Venison's dear, isn't it?" (Jimmy Carr) "An escala...
