Implement a number of primaries present in GNU find, but not present
in our find.
The following are nops because they aren't relevant to our find:
-ignore_readdir_race
-noignore_readdir_race
-noleaf
The following aliaes were created:
-gid -> -group [2]
-uid -> -user [2]
-wholename -> -path
-iwholename -> ipath
-mount -> -xdev
-d -> -depth [1]
The following new primaries were created:
-lname like -name, but matches symbolic links only)
-ilname like -lname but case insensitive
-quit exit(0)
-samefile returns true for hard links to the specified file
-true Always true
I changed one primary to match GNU find since I think our use of it violates
POLA
-false Always false (was an alias for -not!)
Also, document the '+' modifier for -execdir, as well as all of the above.
This was previously implemented.
Document the remaining 7 primaries that are in GNU find, but aren't yet
implemented in find(1)
[1] This was done in GNU find for compatibility with FreeBSD, yet they
mixed up command line args and primary args.
[2] -uid/-gid in GNU find ONLY takes a numeric arg, but that arg does the
normal range thing that. GNU find -user and -uid also take a numberic arg,
but don't do the range processing. find(1) does both for -user and -group,
so making -uid and -gid aliases is compatible for all non-error cases used
in GNU find. While not perfect emulation, this seems a reasonable thing
for us.

Implement a -delete option to find. The code is extremely paranoid and
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. :-)

The following new primaries were created:
-lname like -name, but matches symbolic links only)
-ilname like -lname but case insensitive
-quit exit(0)
-samefile returns true for hard links to the specified file
-true Always true
I changed one primary to match GNU find since I think our use of it violates
POLA
-false Always false (was an alias for -not!)
Also, document the '+' modifier for -execdir, as well as all of the above.
This was previously implemented.
Document the remaining 7 primaries that are in GNU find, but aren't yet
implemented in find(1)
[1] This was done in GNU find for compatibility with FreeBSD, yet they
mixed up command line args and primary args.

normal range thing that. GNU find -user and -uid also take a numberic arg,
but don't do the range processing. find(1) does both for -user and -group,
so making -uid and -gid aliases is compatible for all non-error cases used

for us.

Implement a number of primaries present in GNU find, but not present

The following are nops because they aren't relevant to our find:

The following new primaries were created:

I changed one primary to match GNU find since I think our use of it violates

Implement a number of primaries present in GNU find, but not present

The following aliaes were created:

As they were really global variables that took effect before the traversal

As
|
|
|
|
.Ic -print
|
|
|
|
always evaluates to true, the standard order of evaluation
|
|
|
|
implies that
|
|
|
|
.Ic -depth
|
|
|

would never be evaluated.

As there is no delimiter separating options and file names or file

|
|
|

|
2001-05-16 13:53:19 +00:00

|

Implement a -delete option to find. The code is extremely paranoid and
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. :-)
