Tiii....mare tolomac mai sunt.
Sa va dea dumnezeu sanatate tuturor, ca ma nu ma gindeam sub nici o
forma ca greseala e in crontab! Deja incepusem sa scriu un alt script
:-))))))))
Uneori din cauza padurii nu vezi copacii :-).
Multumita voua am rezolvat problema in timp util.
Am mai patit chestii daste cu scripturi scrise pe sheluri mai noi care
pe sheluri vechi dadeau tot felul de erori, si eram superconvins ca e
problema de bash scripting.
Inca o data mii de multumiri si sa traiti 100 de ani :-))))
Regards,
Alex
