In general to fit with the standard 0 is for a good return value, aka success. >0 is for anything else. Many system programs will adhere to the standards set by the OS, which are often enumerated in a sysexits.h file or some such. And most of the time for *nixes they are going to be similar across systems that have a similar heritage. For instance exit codes on systems deriving more from System V or BSD will be closer, but systems that are not directly descended from one or the other probably will be more arbitrary. But it is really up to whatever the program says are its exit values. perldoc -f exit For more. Check the documentation or source for whatever program you are calling. If you are writing your own and plan to have users check exit values then please document them clearly. http://danconia.org -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] <http://learn.perl.org/> <http://learn.perl.org/first-response>
