2019-06-07Implement stat %C and find %Z.Elliott Hughes
We'd documented find %Z but not implemented it. We'd neither documented nor implemented stat's corresponding %C (they'd already taken %Z for ctime, which is ironic because %c/%C sounds more obvious than %z/%Z for that to me).
2019-05-29Teach find -printf about %.Ns patterns, tweak help text, add tests.Rob Landley
2019-05-25find: add -printf support.Elliott Hughes
This only implements the format specifiers that I've seen used in the wild (which is actually a significant fraction of the total supported by findutils' find). The most obvious gap is in the time support. I'm happy to add more, but didn't want to add stuff "just because". I'd say %A@, %C@, and -- for SELinux users -- %Z are probably the most plausibly useful formats still missing. I don't think the human-readable date formatting is particularly useful unless someone's seen it actually used in the wild. The %T+ "full ISO" format being the most likely exception to that. Anyway, this is enough for me get started building AOSP with toybox find.
2019-03-25find: fix inverted -exec exit statusVidar Holen
The return value of -exec was the command's exit code, which did not account for the fact that an exit code of zero means success, while in C, zero means failure. From POSIX: > the primary shall evaluate as true if the utility returns a zero > value as exit status This commit flips the return value, and adds two tests.
2019-03-10find: minor whitespace cleanup.Elliott Hughes
2019-03-10find: improve -context behavior on failure.Elliott Hughes
2019-03-09find: add -context.Elliott Hughes
Tested manually on an Android device with: adb shell find /system -context u:object_r:wait_for_keymaster_exec:s0 adb shell find /system/bin -context '"*key*"' adb shell find /system/bin -context '"*tool*"'
2019-02-13find: fix -path/-ipath and add -wholename/-iwholename synonyms.Elliott Hughes
Plus new tests.
2018-10-27Zach Van Rijn asked for "find -empty".Rob Landley
2018-08-19Comment tweak.Rob Landley
2017-11-21Make find -exec + obey ARG_MAX just like xargs.Elliott Hughes
This isn't ideal, but it matches xargs and none of us is likely to have time to do the best possible thing any time soon. Bug: http://b/65818597 Test: ./toybox find /usr/local/google/ndkports/ -exec echo {} +
2016-12-20Add units for -atime and friends. (Also legacy -amin alias, but not in help textRob Landley
because there's no -asec or -ahour.)
2016-08-18Change xgetpwnamid/xgetgrnamid to xgetuid/xgetgid returning the id numberRob Landley
instead of a struct. This means it can return "12345" even if that user/group doesn't exist in /etc/passwd and similar. All the users were immediately dereferencing it to get pw_uid or gr_gid anyway, so just return it directly and adjust the users. This fixes things like "chown 12345:23456 filename".
2016-08-04Make xopen() skip stdin/stdout/stderr, add xopen_stdio() if you want stdout,Rob Landley
add xopenro() that takes one argument and understands "-" means stdin, and switch over lots of users.
2016-07-12Implement NOP find -noleafRob Landley
2016-05-20Add bufgetgrgid()Rob Landley
2016-04-25Fix find bug reported by Tom Marshall, add test for it, and while we're at itRob Landley
fix two tests looking for a too-specific error message (so TEST_HOST failed).
2016-03-07Cleanup pass on the dirtree infrastructure, in preparation for making rm -rRob Landley
handle infinite depth. Fix docs, tweak dirtree_handle_callback() semantics, remove dirtree_start() and don't export dirtree_handle_callback(), instead offer dirtree_flagread(). (dirtree_read() is a wrapper around dirtree_flagread passing 0 for flags.)
2016-02-05Another fix from Josh Gao to avoid a null pointer dereference, andRob Landley
minor cleanup of previous commit.
2016-02-05Fix segfault when `find -iname` gets no argument.Josh Gao
2016-02-01Add find -deleteRob Landley
2016-01-14Make "find -execdir toys echo {} +" batch correctly and show topdir results.Rob Landley
I dunno if find -execdir should show depth-first like it's doing, bit given that ubuntu's treating "+" and ";" the same for execdir... eh? Also, testing "find toys tests -mindepth 2 -execdir echo {} +" against the toybox source is easy (and why if (revert) fchdir() is needed), but adding that to the test suite means making a nontrivial hierarchy of files to test against (don't wanna use the project source because it's expected to change in ways that would break the tests)... The old "real world data vs test data" problem.
2016-01-05Work towards making "find . -execdir echo {} + -execdir ls {} +" work,Rob Landley
(not finished yet) plus some error message improvements.
2016-01-02Fix find --prune.Rob Landley
2016-01-02Fix "find . -exec echo {}" segfault, and stop measuring environment space,Rob Landley
The segfault was spotted/fixed by Daniel K. Levy back in September, and again by Isabella Parakiss yesterday. While we're there, remove the environment size measurement code (the 128k limit was lifted by linux commit b6a2fea39318, which went into 2.6.22 released July 2007).
2015-12-06Rename dirtree->data to dirfd, and don't store symlink length in it.Rob Landley
2015-12-06Enable matching any perm bits.Gilad Arnold
Includes tests for the new feature, and a failure case for the minimal perms test as well. Also some typo fixing / massaging the help text so it fits in 80 columns.
2015-11-19Fix find -perm.Elliott Hughes
1) It read st_dev instead of st_mode. 2) It reversed the semantics of absolute vs minimal ('-' prefixed) tests. Add tests for these, and move the "unterminated -exec" test into the "Still fails" section because it's still dumping core for me.
2015-09-12Fix a find segfault.Rob Landley
Elliott Hughes found a bug https://android-review.googlesource.com/#/c/170020/ and Daniel K. Levy worked out the problem: the user/group/newer arguments to find weren't consuming their arguments when not checking the results of their comparison (because an earlier test had already caused their parenthetical group to fail). This confused the argument parsing logic and could lead to segfaults. I applied a different fix that reorganized the existing tests instead of adding a new test. (Looks like a big commit but it's mostly whitespace due to extra curly brackets changing indendentation levels.)
2015-09-07Remove prompt argument from yesno(), caller can fprintf(stderr, "blah") itself.Rob Landley
This fixes the build break, the change to yesno() prototype accidentally got checked in last commit. (Oops, sorry.)
2015-08-01Move strlower() from find to lib.Rob Landley
2015-07-10find: add -inum optionGreg Hackmann
-inum is a commonly implemented extension to search by inode number. Linux's fs-layer tracepoints log many events in terms of inodes, so "find -inum" is useful for mapping those events back to specific files.
2015-05-10Cleanups of dirtree_start() calls. (Don't need to feed in flag values, justRob Landley
symfollow true/false.)
2015-05-09Add DIRTREE_SHUTUP to disable dirtree warnings if file vanishes out fromRob Landley
under traversal. Pass through full flag set in dirtree_add_node(), add dirtree_start() wrapper to provide symlink-only behavior (avoiding a lot of DIRTREE_SYMFOLLOW*!!(logic) repeated in callers).
2015-03-21Another bug from David Halls: find -exec wasn't consuming its argument when ↵Rob Landley
it didn't activate. test: find . -name README -exec echo one '{}' ';' -or -exec echo two '{}' ';'
2015-03-12Make find accept numeric uid/gid, and simplify makedevs using the new ↵Rob Landley
infrastructure.
2015-03-02On 64 bit, subtracting two pointers produces a long result. On 32 bit, it's ↵Rob Landley
an int. Even though long _is_ 32 bits on a 32 bit systems, gcc warns about it because reasons. Also, the warning being that "expects int, but type is wchar_t"... no, type is not wchar_t. Type is probably long. Specify the ACTUAL TYPE, not the random typedef alias for it. If the translated type _did_ match, there wouldn't be a warning! (This is why c89 promoted all arguments to int, precisely so this wasn't a problem.)
2014-11-22As long as Android's going to require fortify, fixup the warnings it generates.Rob Landley
2014-09-14find -xdev should return mount points, just not contents.Rob Landley
2014-09-14Split xpopen() into xpopen_both(), xpopen(), and xrun() depending on whether ↵Rob Landley
we want to redirect both, one, or neither of stdin/stdout.
2014-09-08Add error test and fix memory leak, reported by Ashwini Sharma.Rob Landley
2014-08-07Fix -mindepth and -maxdepth to not drill down into excluded directories.Rob Landley
The fact other implementations don't implement "! -mindepth" doesn't mean we can't. Also, find uses +N, N, -N for everything else but this extension doesn't. Also, -depth already had a definition and this has nothing to do with that. It's a poorly thought-out extension, is what I'm saying.
2014-08-05More find bugfixes.Rob Landley
2014-08-05Rereading posix find.c page: "Specifying more than one of the ↵Rob Landley
mutually-exclusive options -H and -L shall not be considered an error. The last option specified shall determine the behavior of the utility."
