Depends on how you are running Fuseki? You have set, env, declare and
export.
dick@Dick-M3800:~$ name=a
dick@Dick-M3800:~$ echo ${name}
a
dick@Dick-M3800:~$ declare name=b
dick@Dick-M3800:~$ echo ${name}
b
dick@Dick-M3800:~$ export name=c
dick@Dick-M3800:~$ echo ${name}
c
With export the variable is available in sub shells.
