Perl Exception Handling
considered to be of bad quality. The program stops if an error occurs. So a proper error handling is used to handle various type of errors, which may occur during a program execution and take appropriate action instead of halting program completely. You can identify and trap an error in a number of different ways. Its very easy to trap errors in Perl and then handling them properly. Here are few methods which can be used. The if statement The if statement is the obvious choice when you need to check the return value from a statement; for example − if(open(DATA, $file)){ ... }else{ die "Error: Couldn't open the file - $!"; } Here variable $! returns the actual error message. Alternatively, we can reduce the statement to one line in situations where it makes sense to do so; for example − open(DATA, $file) || die "Error: Couldn't open the file $!"; The unless Function The unless function is the logical opposite to if: statements can completely bypass the success status and only be executed if the expression returns false. For example − unless(chdir("/etc")){ die "Error: Can't change directory - $!"; } The unless statement is best used when you want to raise an error or alternative only if the expression fails.
