So today I noticed something weird on my phone. I used a terminal emulator to see what I could do with it, and noticed that there is a file called ubuntu.sh. I tried to run it and got all sorts of permission denied errors, and then I decided to root my phone. But now I'm nervous to run it, does anyone know what it does or why it is there?

edit I forgot to mention that I have an AT&T Morotola Atrix 4G running Android 2.3.6. Also when I use the app SSHDroid to go into my phone from my Ubuntu machine, I'm greeted with this:

"The programs included with the Ubuntu system are free software; the exact distribution terms for each program are described in the individual files in /usr/share/doc/*/copyright.

Ubuntu comes with ABSOLUTELY NO WARRANTY, to the extent permitted by applicable law.

Also, here are the contents of ubuntu.sh

#!/bin/sh
export PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
export LD_LIBRARY_PATH=/usr/lib:/usr/local/lib

# make sure no left-over pidfiles, etc.

This is really strange, any ideas?
