If you're trying to set environmental variables, you'll need to use export before the rest of the statement. 
e.g.
export MYVAR=1 
Setting environmental variables is covered on page 29 of the Bio-Linux tutorial:

I hope that's the information you were looking for. 

Best wishes,

Hello, I’m using Biolinux 8 on a university PC (I login as user and not admin) and I’m having problem with a very basic task – assigning variables in the shell!    I type something very simple like     a=1     and I get the error: command “a=” not found  or the following (which was working perfectly in Linux on my laptop)    LIST="$(ls | grep "fastq$")"    And I get the error “Illegal variable name”    What might be wrong?    Any clue is very appreciated!    Giulia    Dr Giulia Zancolli Molecular Ecology and Fisheries Genetics Lab School of Biological Sciences
