There are many Linux commands that are available on Android devices when you are using the terminal emulator app.
Firstly the ls command. This is used to list files in a directory.
Then the cat command; this is used to view the contents of a text file.
The mv command will move a file from one folder to another; or from one filename to another.
If you want to list the last commands executed in the terminal emulator app; the hash command will perform this task.
There is a nice Linux command list in this app; this is a good reference for the Linux user: https://play.google.com/store/apps/details?id=com.application.LinuxCommandList&feature=search_result#?t=W251bGwsMSwxLDEsImNvbS5hcHBsaWNhdGlvbi5MaW51eENvbW1hbmRMaXN0Il0..

Here is a video about the upcoming Ubuntu for ARM based Android mobile devices. This will be very interesting when this is finished; running a desktop Linux distribution on a mobile phone will be a reality.
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.
