Ho uno script in cron che lancia dei comandi di sistema con system.

Cose tipo : system (“rm test.txt”) //

Volevo sapere come posso intercettare gli errori che vengono generati  
dal comando lanciato. (“File not found” - “Permission denied” - etc)

Grazie

Simone

" Executes cmd in a subshell, returning true if the command was found  
and ran successfully, false otherwise. An error status is available  
in  
$?. The arguments are processed in the same way as for Kernel::exec."
