Hi Alex :-),
Nu , nu.... problema nu este la ordinea executarii, ci in scriptul in
sine. Am facut un mic test:
1. am lasat in crontab numai o linie de forma:
*/1 * * * * root /root/bin/rescanscsi -r &> /root/xxx.log
Apoi ma uit in /var/spool/mail/root si in /root/xxx.log. Iata
rezultatele:
[root@server bin]# cat /root/xxx.log
/bin/sh: root: command not found
[root@server bin]#
[root@server bin]# cat /var/spool/mail/root

^^^^^^^^^^^^
Deci e limpede ca la executatea scriptului, probabil ca nu initializeaza
o variabila si de eroarea in cauza!
Si inca ceva: scriptul ruleaza corect in consola daca sunt logat ca
root.
Oricum, daca are cineva un hit, este binevenit.
Atasez in continuare si scriptul rescanscsi,pentru cazul in care se
prinde cineva mai rpd decit mine de unde apare aceasta eroare:
