documented behavior. Only a certain set of file flags were recognized,
and "no" flags did not match files that have corresponding flags bits
turned off.
Fix and extend the -flags functionality as follows:
: -flags [-|+]<flags>,<notflags>
: The flags are specified using symbolic names (see chflags(1)).
: Those with the "no" prefix (except "nodump") are said to be
: <notflags>. Flags in <flags> are checked to be set, and flags in
: <notflags> are checked to be not set. Note that this is different
: from -perm, which only allows the user to specify mode bits that
: are set.
:
: If flags are preceded by a dash (``-''), this primary evaluates
: to true if at least all of the bits in <flags> and none of the bits
: in <notflags> are set in the file's flags bits. If flags are pre-
: ceded by a plus (``+''), this primary evaluates to true if any of
: the bits in <flags> is set in the file's flags bits, or any of the
: bits in <notflags> is not set in the file's flags bits. Otherwise,
: this primary evaluates to true if the bits in <flags> exactly match
: the file's flags bits, and none of the <flags> bits match those of
: <notflags>.

As an extra bonus, the program is ANSI-fied - the original version
relies on some obscure features of K&R C.

-E Interpret regular expressions followed by -regex and -iregex op-
tions as extended (modern) regular expressions rather than basic
regular expressions (BRE's). The re_format(7) manual page fully
describes both formats.
-iname pattern
Like -name, but the match is case insensitive.
-ipath pattern
Like -path, but the match is case insensitive.
-regex pattern
True if the whole path of the file matches pattern using regular
expression. To match a file named ``./foo/xyzzy'', you can use
the regular expression ``.*/[xyz]*'' or ``.*/foo/.*'', but not
``xyzzy'' or ``/foo/''.
-iregex pattern
Like -regex, but the match is case insensitive.
These are meant to be compatible with other find(1) implementations
such as GNU's or NetBSD's except regexp library differences.

interface, and statically link them to the programs using them.
These functions, upon reflection and discussion, are too generically
named for a library interface with such specific functionality.
Also the api that they use, whilst ok for private use, isn't good
enough for a libc function.
Additionally there were complications with the build/install-world
process. It depends heavily upon xinstall, which got broken by
the change in api, and caused bootstrap problems and general mayhem.
There is work in progress to address future problems that may be
caused by changes in install-chain tools, and better names for
{g|s}etflags can be derived when some future program requires them.
For now the code has been left in src/lib/libc/gen (it started off
in src/bin/ls).
It's important to provide library functions for manipulating file
flag strings if we ever want this interface to be adopted outside
of the source tree, but now isn't necessarily the right moment
with 4.0-release just around the corner.

string to u_long and back using two functions, flags_to_string and
string_to_flags, which co-existed with 'ls'. As time has progressed
more and more other tools have used these private functions to
manipulate the file flags.
Recently I moved these functions from /usr/src/bin/ls to libutil,
but after some discussion with bde it's been decided that they
really ought to go in libc.
There are two already existing libc functions for manipulating file
modes: setmode and getmode. In keeping with these flags_to_string
has been renamed getflags and string_to_flags to setflags.
The manual page could probably be improved upon ;)
I added $FreeBSD$ whicle I was here. The patch wasn't usable anymore
due to its age so I adapted it.

disables the -fstype option if compiled with a pre-processor that
defines __NetBSD__. With the FreeBSD built pre-processor, find can only
be built with the FreeBSD libc. So when running with a NetBSD kernel,
FreeBSD's libc will have to return ENOSYS for things that NetBSD
doesn't support. That's life in a hybrid world.

goes to a fair degree of trouble to enable something like this to
be safe: cd /tmp && find . -mtime +7 -delete
It removes both files and directories. It does not attempt to remove
immutable files (an earlier version I showed to a few people did a chflags
and tried to blow away even immutable files. Too risky..)
It is thought to be safe because it forces the fts(3) driven descent to
only do "minimal risk" stuff. specifically, -follow is disabled, it does
checking to see that it chdir'ed to the directory it thought it was
going to, it will *not* pass a pathname with a '/' character in it to
unlink(), so it should be totally immune to symlink tree races. If it runs
into something "fishy", it bails out rather than blunder ahead.. It's better
to do that if somebody is trying to compromise security rather than risk
giving them an opportunity. Since the unlink()/rmdir() is being called
from within the current working directory during the tree descent, there
are no fork/exec overheads or races.
As a side effect of this paranoia, you cannot do a
"find /somewhere/dir -delete", as the last argument to rmdir() is
"/somewhere/dir", and the checking won't allow it. Besides, one would use
rm -rf for that case anyway. :-)
