Here is a patch that adds egrep -L support (the opposite of egrep -l).
I realize this is probably too late for 1.0. But I offer it for your
future consideration.
egrep -L is used in some networking startup scripts I inherited.

add sed -r support.
I bumped into a couple of things that want to use extended regular expressions
in sed, and it really isn't that hard to add. Can't say I've extensively
tested it, but it's small and isn't going to break anything that doesn't use
it, so...

Run this test, against both busybox and a non-busybox version of "tee".
while true; do i=$[$i+1]; echo "hello $i"; sleep 1; done | ./busybox tee
Now run the busybox one again with the following small patch applied:
Hi,
I just re-reviewed the patch I just sent...and it needed to be BUFSIZ-3 in
dos2unix.c . tempFn is BUFSIZ so the last addressable spot it BUFSIZ-1. The loop
increments by 2. That's why it should be BUFSIZ-3.

Hello,
I found and patched 2 more bugs. The first is a misplaced semi-colon. The second
one is a buffer overflow. I doubt the buffer overflow is triggered in real life.
But you never know what those wily hackers are up to.
Thanks,

Hello,
Last November a bug was found in iproute. CAN-2003-0856 has more information.
Basically, netlink packets can come from any user. If a program performs action
based on netlink packets, they must be examined to make sure they came from the
place they are expected (the kernel).
Attached is a patch against pre8. Please apply this before releasing 1.00 final.
All users of busy box may be vulnerable to local attacks without it.
Best Regards,
Steve Grubb

Hi,
the following output is from BusyBox 1.0.0-pre10:
~ # ip link help
ip: Command "help" is unknown, try "ip link help".
tk
This patch fixes it by removing the advertisements for
the "ip blah help" stuff that is not implemented.
the _destination_ file. (Ah hah! That works _much_ better...) I
implemented the behavior, I just forgot to test this corner of it. My fault,
sorry...
No, gnu sed -i doesn't preverve ownership information. I checked.
Permissions, yes, ownership info, no.
Rob
that the _only_ change to is that gnu sed has been replaced with busybox sed.
And ncurses' install phase hangs. I trace it down, and it's trying to run
gawk. (Insert obligatory doubletake, but this is FSF code we're talking
about, so...)
It turns out gawk shells out to sed, ala "sed -f /tmp/blah file.h". The
/tmp/blah file is basically empty (it contains one character, a newline). So
basically, gawk is using sed as "cat". With gnu sed, it works like cat,
anyway.
With busybox sed, it tests if its command list is empty after parsing the
command line, and if the list is empty it takes the first file argument as a
sed command string, and if that leaves the file list empty it tries to read
the data to operate on from stdin. (Hence the hang, since nothing's coming
in on stdin...)
It _should_ be testing whether there were any instances of -f or -e, not
whether it actually got any commands. Using sed as cat may be kind of
stupid, but it's valid and gawk relies on this behavior.
Here's a patch to fix it, turning a couple of ints into chars in hopes of
saving a bit of the space this adds. Comments?
Rob
The linux kernel doesnt allow hard links to directories, SUS says its
implementation specific.
cramfs gives empty directories and 0 length files the same node it
makies it difficult to distinguish from hard links.
This is a bulk spelling fix patch against busybox-1.00-pre10.
If anyone gets a corrupted copy (and cares), let me know and
I will make alternate arrangements.
Erik - please apply.
Authors - please check that I didn't corrupt any meaning.
Package importers - see if any of these changes should be
passed to the upstream authors.
I glossed over lots of sloppy capitalizations, missing apostrophes,
mixed American/British spellings, and German-style compound words.
What is "pretect redefined for test" in cmdedit.c?
Good luck on the 1.00 release!

He,
there is a bug in HUSH's handling of "if" / "elif" commands:
$ if true
> then
> echo 1
> elif
> true
> then
> echo 2
> elif
> true
> then
> echo 3
> else
> echo 4
> fi
1
2
3
$
The same bug exists in all versions of HUSH from BB v0.60.x up to and
including v1.00-pre9. The attached patch fixes this:
$ if true
> then
> echo 1
> elif
> true
> then
> echo 2
> elif
> true
> then
> echo 3
> else
> echo 4
> fi

$
