Hi Paul,

"GREP" is there, here is the result after I execute "busybox ps | busybox grep bin":

# busybox ps | busybox grep bin 1042 root 0 SW< [binder] 1093 root 332 S /sbin/ueventd 1910 root 840 S /system/bin/sh 1911 system 900 S /system/bin/servicemanager 1912 root 4076 S /system/bin/vold 1913 root 4052 S /system/bin/netd 1914 root 764 S /system/bin/debuggerd 1915 radio 4504 S /system/bin/rild 1916 root 64348 S zygote /bin/app_process -Xzygote /system/bin --zygot 1917 media 18132 S /system/bin/mediaserver 1918 bluetoot 1384 S /system/bin/dbus-daemon --system --nofork 1919 root 912 S /system/bin/installd 1920 keystore 1956 S /system/bin/keystore /data/misc/keystore 1921 bluetoot 748 S /system/bin/faketsd 1922 root 1388 S /sbin/adbd 2212 root 1456 S busybox grep bin "

For the link, Yongqin and I have discussed about it, see below:

############################################################################ Hi Yongqin,

Looks good, but I'm thinking this work should be done by us or by our customers. As we know, our customers are not the ordinary end users, they are manufactures or developers.

For those ordinary end users, we need to provide a powerful and easy to use system; but for the manufactures and developers, we need to provide a different stuff - a stable framework and interface. This "link files" walk around looks like a "Hack" way rather than standard, and this "Hack" thing need to be done by developers (our customers) according to their requirement.

I will discuss this around, but if we decide to do this, we have to make something inside busybox and our build system to let things done during the build period, not manually or automatically generate them after flashed to the SD card.

Thank you!

Hi, Botao

You're right, if we use busybox as our default shell and command
line tool, it will be better. But there may exist a standard for
any Android system in my opinion. Currently, the third party
components are playing an "optional" role, not default. I'm not
sure change this status whether breaks some policies in AOSP or
any other communities.

what about to do like this:

1. make a directory /system/busybox
2. create sub command link files in that directory # the busybox command itself can also be installed in /system/bin

directory. 3. if we want to use the commands of busybox, then we can change the path in our shell like: export PATH="/data/busybox:${PATH}" 4. if we don't like use the commands of busybox, we can do as now. this will not change the "optional" role i think.

Thanks, Yongqin Liu

I will discuss this topic with some guys in future, but we still
use Android's own "unfriendly" command line tools by default at
present.


Thank you!

Hi, botao

I have just use the attachment file to take a try with images of
linaro-android-leb-panda build#252.
the busybox and some it's sub commands works well.

But in my opinion it's better to create link for each sub command
at installation.
Then we just need to add the link files' parent path to the
environment PATH, and can simply use the sub command.
Not as now should use the busybox command at the front.
Now if we want use the grep command, we need specify as "busybox
grep" but not only  "grep".
Especially, when I write a shell including if sentence(as
sentence in the attachment file), we need to write like this:

    if /system/bin/busybox [ $# -lt 1 ]; then

It's a little not convenient I think.

Thanks,
Yongqin Liu

    Hi Yongqin,

    Just test it can be run or not. Run some basic commands, such
    like busybox top, busybox vi, busybox ps | busybox grep
    XXX..., something like that.

    I don't have test cases at my side. And this is the first
    time I integrated the entire busybox source code to our
    Android platform. I would like to be ensure it works on every
    board first.

    Thanks.

Hi Botao, it's really late right now and I don't have time to look at it right now, but I played with it a bit on Panda recently and it seemed to mostly work. However I had to run 'busybox [COMMAND]' to use it, links for running the commands directly under busybox did not seem to exist. If this is still the case, that would be useful to fix. Also, I noticed that grep was not enabled. That's one of the things that would *really* be useful to have. Any way we could get grep support enabled?

Thanks, Paul Larson

Hi,

The busybox source code has been integrated to Linaro Android platform
for all boards, so I'd like to ask help from you to test it. I have
tested it on my Origen board, and it works well.

Thank you!
