shell

I'm following the instructions for installing the Android SDK http://developer.android.com/sdk/installing.html#Installing
So far just downloaded and then this instruction seems easy editing my .bashrc file to add this

From the android install instructions: export PATH=${PATH}:/tools

export PATH=$PATH:/home/dolbert/Desktop/android-sdk-linux/tools

Then I test to see if it took

I get this error
bash: export: `/home/dolbert/Desktop/android-sdk-linux/tools': not a valid identifier

I have a dedicated server but software seems quite outdated now (Fedora something) yum and apt-get fail and think its time to upgrade or change my repos but not sure what version of linux I have on it.

I'd like to be able to just update what I not sure how to set up repos
