Hi uva,

As far as your question goes, did you read the documentation? If so is there something in there that you dont understand? Also if you have not done so already, please read How do I post a question effectively? and How do I compose an effective node title?.

I'm going to assume that the underlying question is why different exit values are useful or how they should be used or handled. This is complicated, as it's not necessarily consistent across platforms.

Much of what exit codes do can better understood by reading the documentation for how Perl gets the exit codes back from programs that it runs -- e.g. with system and $? -- and related docs on portability:

• system

• perlvar (look at the entry for $? and the section on "Error Indicators")

• perlport (look for system)

[mickeyn]

the expression returned by the exit is the 'exit status' which will be read (and maybe dealt with) by whoever is executing the code and recieves it (shell, eval ...).

different exit statuses can be useful for figuring which kind of error occured in the program.

Enjoy,
Mickey

What part of the rather extensive documentation for exit did you not bother to read understand that's left you confused?
