Name
die
Synopsis
die message
Prints message to the
standard error output and exits the Perl program with a nonzero
exit status. message can be a list
value, like the arguments to print, from which the elements are
concatenated into a single string for output. If
message does not end with a newline
(\n), the current script
filename, line number, and input line number (if any) are appended
to the message with a newline. With no argument, the function
outputs the string Died as its
default.
die exits the programs
with the current value of the $! variable, which contains the text
describing the most recent operating system error value. This
value can be used in the message to
describe what the problem may have been.
die behaves differently
inside an eval statement. It
places the error message in the $@ variable and aborts the eval, which returns an undefined value.
This use of die can raise
runtime exceptions that can be caught at a higher level of the
program.
