Thanks claes
I find the problem, the folder is correct and I have all permssion to write it.
But I follow your suggestion and I recontrol the path,
So I execute the below:
wb_cmd -q -i create snapshot /file=\"/home/pwrp/sviluppo/Proview4.6.1/pwr/src/wbl/pwrs/src/\"/out=\"/home/pwrp/sviluppo/ Proview4.6.1/rls_dbg/os_linux/hw_x86/rt/load/pwrs.dbs\"
and the error was:
** Cannot open file: /home/pwrp/sviluppo/proview4.6.1/rls_dbg/os_linux/hw_x86/rt/load/pwrs.dbs
the difference is that first the folder is in \"... /Proview....\", and is correct, but the wb_cmd search the pwrs.dbs in \".../proview...\" with lower \"p\".
I've renamed the folder, reconfigured the enviroment and I rebuild all, it work fine.
