2019-03-09Half-finished su change checked in, sorry.Rob Landley
2019-03-07Add reset_env() and make su and login use it. Do long-delayed login cleanup.Rob Landley
2019-03-06More tar cleanup.Rob Landley
Dear gcc: if (i || node=blah) x = i ? blah : node; Don't complain "node may be used uninitialied", it can't be. That warning is a gcc bug. (I should add a node = node to the initialiation to shut up the warning, but gcc has failed to emit "may be used uninitialized" reliably for 15 years and it still does.)
2019-03-04More tar cleanup.Rob Landley
2019-03-04Don't print (null) in error messages.Rob Landley
2019-03-04Consistently use ARRAY_LEN.Elliott Hughes
2019-03-03Cleanup pass on tar.Rob Landley
2019-03-02Make top -H show TID instead of PID, not collate %CPU into parent threadRob Landley
(resulting in 400% CPU with 4 threads), and add a couple comments.
2019-03-02Promote devmem.Rob Landley
2019-03-02Improve help consistency.Elliott Hughes
More consistent tense, capitalization, and punctuation. A few commands were missing an introductory line, so I copied those from the first comment line.
2019-03-02Fix instances of "Usage:" rather than "usage:".Elliott Hughes
2019-03-02devmem: new command.Elliott Hughes
Intended to replace Android's toolbox `r`, but behaving more like a drop-in replacement for busybox's `devmem`.
2019-03-01William Djupström pointed out we need to chown() the tty.Rob Landley
Do the FLAG() and short argument variable cleanups while we're there.
2019-03-01Yes it's a one instruction race, but it bothers me.Rob Landley
2019-03-01Minor tweaks.Rob Landley
2019-02-27top: fix -b.Elliott Hughes
We hadn't updated the output in -b mode ever since I broke this in 2016. Bug: http://b/126347053 "top doesn't seem to update the output when run in batch mode (-b)"
2019-02-25arp: inline get_hw_add and minor sscanf error handling cleanupColin Davidson
2019-02-24grep: add missing long synonyms used in AOSP.Elliott Hughes
2019-02-23One last (for now) typo.Elliott Hughes
This one actually introduced by my last cleanup. (But helpfully pointed out by the machines when I tried to upload my last cleanup to the AOSP gerrit...)
2019-02-23Add UUID= support to mount, via blkid -U.Rob Landley
2019-02-23Add blkid -U and -L.Rob Landley
2019-02-23Promote mcookieRob Landley
2019-02-23Cleanup mcookie.Rob Landley
2019-02-23Here's an 'mcookie' implementation for toybox.Isaac Dunham
mcookie simply prints out 16 bytes of entropy in hexadecimal; it is typically used as the source for the "MIT magic cookies" that X11 uses for "secure" connections. The only implementation I know of is in util-linux; the problems with its documented behavior motivated me to write an alternate implementation. Specifically, getting 128 bytes from the kernel and finding the MD5 sum is not a sane PRNG, especially when only 16 bytes are needed.
2019-02-23Bumper typo cleanup.Elliott Hughes
Inspired by some of the small patches that have gone by recently. Limited to only things found in `generated/help.h`, plus a wider cleanup for the more common "milisecond" typo.
2019-02-23Switch losetup to short arg var style and force typecasts for printf.Rob Landley
2019-02-23Switch mount to use FLAG() macros.Rob Landley
2019-02-21Fix typo in helpKevin van der Kamp
2019-02-21getfattr: add --only-values.Elliott Hughes
Needed to improve cp(1) testing.
2019-02-20Exit code should indicate _which_ signal oneit's exiting due to.Rob Landley
2019-02-20Simplify netcat a lot using the net.c upgrades from last commit.Rob Landley
2019-02-20Minor cleanups, mostly wordwrapping.Rob Landley
2019-02-19grep: add --quiet and --silent synonyms for -q.Elliott Hughes
--quiet is used 3x more than --silent in my corpus, but they're both used surprisingly often. (Surprising to someone who thinks -q is part of the core set of grep options that "everybody knows".)
2019-02-18route: fix command argument parsingUros Prestor
2019-02-17top: make the task/thread count add up.Elliott Hughes
Linux has more states than we were giving it credit for, which led to our numbers not adding up. Since the exact details seem to change between versions, and since having code specific to each kernel version is unattractive, go with the heuristic that there are relatively fewer "stopped" states (and they change less frequently), so all unknowns are "sleeping".
2019-02-16Disallow -o "" in top.Rob Landley
2019-02-16top: differentiate tasks (processes) and threads in the header.Elliott Hughes
2019-02-16top: make the column header span the terminal.Elliott Hughes
This also makes everything more readable by separating out the -b no formatting case. The whitespace trimming for -b isn't strictly necessary, but it looks weird if we output unnecessary spaces at the end of the line in -b mode, and we've fixed it before, so let's not regress here. It also seems more logical to do this in the one place where it actually happens.
2019-02-15mountpoint: add missing synopsis.Elliott Hughes
2019-02-15Fix typos: e.g. change "cannonical" to "canonical".Jason Spiro
2019-02-14Use current time for unspecified fields, set weekday to match date.Rob Landley
2019-02-13top: support Enter as a synonym for Space.Elliott Hughes
Both refresh the display in the traditional implementation.
2019-02-13top: use human_readable for the header lines too.Elliott Hughes
Even phones have enough RAM these days that KiB is not a reasonable unit. Traditional top always uses MiB instead of always using KiB, but we may as well just let human_readable pick a unit (that way if KiB is reasonable on your box, that's what you'll get). Before: Tasks: 967 total, 1 running, 581 sleeping, 0 stopped, 0 zombie Mem: 196734820k total,183891564k used, 12843256k free, 5805008k buffers Swap:199888892k total, 719104k used,199169788k free,130367280k cached After: Tasks: 965 total, 2 running, 577 sleeping, 0 stopped, 0 zombie Mem: 188G total, 175G used, 13G free, 5.5G buffers Swap: 191G total, 702M used, 190G free, 124G cached
2019-02-13top: hide the cursor in interactive mode.Elliott Hughes
Matches traditional top.
2019-02-13Oops, missed one.Rob Landley
2019-02-13Use xrecvwait() in ping, and move signal handler setup to start of ping loop.Rob Landley
2019-02-13Move nanomove(), nanodiff(), union socksaddr, and xrecvwait() to lib.Rob Landley
2019-02-13find: fix -path/-ipath and add -wholename/-iwholename synonyms.Elliott Hughes
Plus new tests.
2019-02-13sed: fix endless loop in "b loop" test.Elliott Hughes
Very few places actually check for errors from emit, and I actually see the same endless loop from "sed (GNU sed) 4.4" on current Debian, so I'm not sure this isn't Broken As Designed, but an endless loop spewing "short write" (or saying nothing, in the case of GNU sed) really doesn't feel like useful behavior in face of EPIPE, which really isn't going to fix itself. Certainly not being able to run the sed tests to completion is pretty annoying --- which is why, unless we remove this test as invalid, we should probably also add a SKIP_HOST=1 to the "b loop" test. Note that even with this fix you'll see the error twice: sed: short write: Broken pipe sed: short write: Broken pipe Once from the first = command to fail, and then another from the !FLAG(n) flush of the pattern space.
2019-02-12sed: fix substitution of empty capturing groups.Elliott Hughes
The test for \N where N was larger than the number of capturing groups in the regular expression was incorrect, and firing for cases such as matching __(ARM_)?NR_([a-z]*) against __NR_read, where the first group is empty (because it failed to match) but the second group did match "read". Use regex_t's re_nsub for the error check, and treat rm_so == -1 as a signal to just copy nothing into the result. (Found trying to build minijail in AOSP.)
