In-Depth Information
NOTE
If you log in as
root
, your home directory is
/root
. That is, anyone can
cd /root
to get
into your home directory (though directories are initially locked). If you log in as
debian
,
your home is
/home/debian
. If you were to create a new user called
newuser
, that user's
home would be
/home/newuser
. By default, all non-root (non-superuser) users have their
home directories in
/home
.
The following commands create a new directory for the sensor recipes, change to it, and
use
touch
to create an empty file called
pushbutton.js
:
root@beaglebone:/var/lib/cloud9#
cd /root
root@beaglebone:~#
mkdir boneSensors
root@beaglebone:~#
cd boneSensors
root@beaglebone:~/boneSensors#
touch pushbutton.js
Now, add recipe code to the newly created
pushbutton.js
file to enable it to run:
1. In Cloud9, in the Workspace browser on the left, go to the Preferences wheel and
select Add Home to Favorites (
Figure 1-22
). Now, your home directory will show
up in the Workspace file tree.
2. In the Workspace browser, expand
root
.
3. You will see your newly created
boneSensors
directory; expand it. You will see
your empty
pushbutton.js
4. Double-click the
pushbutton.js
file to open it.
5. Paste the code for the recipe you want to run. This example uses
Example 2-1
.
6. Press ^S (Ctrl-S) to save the file. (You can also go to the File menu in Cloud9 and
select Save to save the file, but Ctrl-S is easier.)
7. In the
bash
tab, enter the following commands:
root@beaglebone:~/boneSensors#
chmod +x pushbutton.js
root@beaglebone:~/boneSensors#
./pushbutton.js
