As you can see, the output of the ps command is different from a Linux machine, but it is still very useful in keeping track of what processes are running on an Android computer. When you are using the Terminal Emulator app on Android and you want to create files with the command-line, type cd /sdcard to navigate to the sd card storage space, then you will be able to create files easily. Typing ps > myps.txt will redirect the output of the ps command to a text file allowing you to review the contents later. The system binaries are stored under /system on Android instead of using the /bin folder in the case of the /system/bin/sh command shell. But it does work very well, and having a command-line shell on your Android device means that you could easily manage files more easily than using the GUI. The inbuilt memory on my Android device is not writable by the command shell even as root, therefore I use the sdcard to create files.
I am a computer enthusiast that has always been interested in maintaining and upgrading computer hardware. I was born on a farm and lived there for 13 years before moving into town. I was always interested in technology and my father always gave me good encouragement for developing my knowledge and interest in tinkering with computers. He was using a computer on the farm but that was in the very late 80`s and late 90`s. Seeing what a computer could do always fascinated me and then I knew that is what I wanted to do. The first time I used Linux was Red Hat 6.2 installed off a single CDROM and I was amazed that you did not need to install any more drivers on my old Intel Celeron machine to be able to enjoy a nice 24BPP desktop and use the GIMP to edit photos and enjoy playing the old Linux games like Xbill. Then a while later I tried Mandrake Linux 9.2 and I was hooked. It came with so much software and was very easy to use as well. Then Mandrake Linux 10 and on through FreeBSD, Debian 3.0, Debian 3.1 Suse Linux 9.2, Suse 10 and onto the Ubuntu distributions although I am using Fedora Core 15 and the Gnome 3 desktop at the moment.
