An Android device or emulator comes with a meager set of 71 command line tools.
Each one is a symbolic link to the executable file
/system/bin/toolbox.

Busybox
is a better set of 219 command line tools,
including Unix classics such as
awk,
find,
and
sed.
It’s already installed on the Samsug Galaxy S5 emulator in Genymotion.
Each tool is a symbolic link to the executable file
/system/xbin/busybox.
The S5 has one link
(length)
with no corresponding tool;
and five tools
(mkdosfs,
nbd-client,
nc,
pipe_progress,
reboot)
have no link.

Download a
prebuilt binary
of Busybox onto your Mac or PC Desktop,
for example
busybox-arm7l
(seven lowercase L).
The executable file
busybox
is in the directory
/system/xbin
on the Genymotion S5 emulator,
so I would like to install it into the same directory on the
Android Nexus 5 emulator
(emulator-5554).
This directory is in a filesystem that is mounted read-only;
we will have to remount it as read-write.

BusyBox is a set of Unix utilities (command line programs) that you can install into the Android Emulator to supplement the meager set that comes with the Emulator. Complete list of approximately 346 utilities.
Download a
prebuilt binary
of BusyBox onto the desktop of your Mac or PC.
The binary file
busybox-armv4tl
worked for Android Emulators running on Macintosh and PC.
When we
push
this file into the Emulator,
we will rename it
busybox.
I would have liked to put
busybox
in one of the directories in my PATH on the Emulator.
# echo $PATH /sbin:/vendor/bin:/system/sbin:/system/bin:/system/xbinBut the directories
/vendor/bin/system/sbin/data/busybox.
cd cd Desktop adb shell mkdir /data/busybox adb shell ls -ld /data/busybox
adb push busybox-armv4tl /data/busybox/busybox 2643 KB/s (1096224 bytes in 0.404s)
adb shell ls -l /data/busybox/busybox -rw-rw-rw- root root 1096224 2013-05-20 18:33 busybox
Turn on the set-uid bit, too.
adb shell # cd /data/busybox # pwd # ls -l busybox -rw-rw-rw- root root 1096224 2013-05-20 18:33 busybox
# chmod 4755 busybox # ls -l busybox (the mode bits should now be changed to rwsr-xr-x) -rwsr-xr-x root root 1096224 2013-05-20 18:33 busybox
A
symbolic link
in Unix
is like an alias on a Mac
or a shortcut on a PC.
We will create 346 symbolic links to the
busybox
file and place them in a new directory named
bbdir.
# cd /data/busybox (You’re already there.) # pwd
# mkdir bbdir # ls -ld bbdir
Is there a way to set the PATH in an
ash
start-up file such as
.profile?
# echo $PATH /sbin:/vendor/bin:/system/sbin:/system/bin:/system/xbin
# export PATH=$PATH:/data/busybox:/data/busybox/bbdir
# echo $PATH /sbin:/vendor/bin:/system/sbin:/system/bin:/system/xbin:/data/busybox:/data/busybox/bbdir
The symbolic links will let us avoid having to write the word
busybox
in front of each command.
Be sure to type
`back quotes`.
# cd /data/busybox # for i in `busybox --list` > do > ln -s /data/busybox/busybox bbdir/$i > done
# cd /data/busybox/bbdir # ls -l # ls -l | more
# busybox --help # busybox --help find
The purpose of the symbolic links is to allow us to say
# find / -name busybox -type f -print /data/busybox/busyboxinstead of
# busybox find / -name busybox -type f -print
# ls -l `find / -name busybox -type f -print` -rwsr-xr-x root root 1075144 2011-07-19 18:47 busybox
# exit
