Well, that depends on what shell you are using and when you want the variables set. From a command line the following apply:

sh       - VAR=my-value; export VAR
bash/ksh - export VAR=my-value
csh/tcsh - setenv VAR my-value

If you want the env vars to be set when you log in, you use the appropriate commands from the above in your shell init files in your home directory, usually:

sh   - .profile
bash - .bashrc
ksh  - .profile
csh  - .cshrc
tcsh - .tcshrc
