Find by permission

Rotwang · 03-05-2008, 03:55 PM

How do I show:

A list of files and directories, recursively, who's public permission is not +r.

I was looking at -perm in find and it looks like it can only find a specific xxx perm? Or else I can't figure it out...

Code:

find \! -perm +004 -ls

?

%find \! -perm +004
usage: find [-H | -L | -P] [-EXdsx] [-f file] [file ...] [expression]
%find \! -perm +004 -ls
usage: find [-H | -L | -P] [-EXdsx] [-f file] [file ...] [expression]

I also tried:

find ./ -perm +004
find ./ -perm -004

Both just listed everything.

What OS and which version of find is this with? And what's with the ugly prompt,
are you using tcsh? :}

And the answer to http://www.linuxquestions.org/questi...81#post3079381 ?

Oh I missed that post sorry. I don't know, how do I tell what shell I'm using? Oh found it:

%echo $0
-csh

How do I tell the distro/os?

Tinkster · 03-05-2008, 07:59 PM

uname -a
is a start.

Oh hell, I feel like an idiot. It's FreeBSD not linux. But does that matter for the find command, aren't they the same code on both? I guess maybe not.

%uname -a
FreeBSD _______ 6.2-RELEASE-p1 FreeBSD 6.2-RELEASE-p1 #1: Mon May 7 14:30:09 EDT 2007

this is what it says in the perm section of man:

Code:

-perm [-|+]mode
             The mode may be either symbolic (see chmod(1)) or an octal num-
             ber.  If the mode is symbolic, a starting value of zero is
             assumed and the mode sets or clears permissions without regard to
             the process' file mode creation mask.  If the mode is octal, only
             bits 07777 (S_ISUID | S_ISGID | S_ISTXT | S_IRWXU | S_IRWXG |
             S_IRWXO) of the file's mode bits participate in the comparison.
             If the mode is preceded by a dash (``-''), this primary evaluates
             to true if at least all of the bits in the mode are set in the
             file's mode bits.  If the mode is preceded by a plus (``+''),
             this primary evaluates to true if any of the bits in the mode are
             set in the file's mode bits.  Otherwise, this primary evaluates
             to true if the bits in the mode exactly match the file's mode
             bits.  Note, the first character of a symbolic mode may not be a
             dash (``-'').

No, not necessarily ... often the versions of tools shipped with
BSD are much closer to the old sysV stuff you also find in Slowaris.

Well ... try the command I've given you in the first response
from a bash rather than a csh. I don't know how to escape the
! in csh.

Fudge ... does the man-page for BSDs find mention ANY logical operators?

Rotwang · 03-05-2008, 09:33 PM

I'm not sure... it doesn't look like it. that -perms thing won't help?

Here's a dump of man find:

Can't seem to get a download link. Only semi-pornographic ads?
