i use the correct format of import Command text
i am the only user of system and i run import command without SUDO because with it, say me "SET THE VUFIND_HOME  variables" and i Did it and i control it correct. 


in Directory /usr/local/vufind/solr/biblio/index/ i have these Files  

1-Segments.gen
2-Segments_01
