RHEL 5 environment variables

[g00ner]

Hi everyone new to the forum and to linux.

I am a windoze admin by birth and need a little help figuring out how to do something in RHEL5.

I have a windows batch file that checks to see what a particular environment variable is and then if it is A it goes and does something and if it is B it goes and does something slighlty different.

How would l do this in RHEL5?

How do l get a list of environment variables? In Windows l would go to the command prompt and type set

How do l set an environement variable?

Thanks in advance.

You can run

env

to get a list of environment variables.

I recommend to read this guide to learn shell scripting: http://tldp.org/LDP/abs/html/ - it's one of the best guides out there.
