okay, so you were actually looking for a graceful shutdown or termination.
or technically saying a interrupt handler..
you probably could use
$SIG{'INT'} = 'interrupt_handler';
sub 'interrupt_handler {
print("Script got a termination signal, shutting down...!\n");
exit; # or may be you want to continue ignoring the signal then dont use exit.
}
I hope that would help.

ABORT(3) Linux Programmer's Manual ABORT(3)
NAME
abort - cause abnormal process termination
SYNOPSIS
#include <stdlib.h>
void abort(void);
DESCRIPTION
The abort() first unblocks the SIGABRT signal, and then raises that signal for the calling process (as though raise(3) was called). This
results in the abnormal termination of the process unless the SIGABRT signal is caught and the signal handler does not return (see
longjmp(3)).
If the SIGABRT signal is ignored, or caught by a handler that returns, the abort() function will still terminate the process. It does this
by restoring the default disposition for SIGABRT and then raising the signal for a second time.
RETURN VALUE
The abort() function never returns.
ATTRIBUTES
For an explanation of the terms used in this section, see attributes(7).
+----------+---------------+---------+
|Interface | Attribute | Value |
+----------+---------------+---------+
|abort() | Thread safety | MT-Safe |
+----------+---------------+---------+
NOTES
Up until glibc 2.26, if the abort() function caused process termination, all open streams were closed and flushed (as with fclose(3)).
However, in some cases this could result in deadlocks and data corruption. Therefore, starting with glibc 2.27, abort() terminates the
process without flushing streams. POSIX.1 permits either possible behavior, saying that abort() "may include an attempt to effect fclose()
on all open streams".
