Terminating on signal SIGINT(2)

唐归来

use strict;
use warnings;
my $total;
my $valid;
my $word;
my %count;
while (<>) {
foreach (split) {
$total++;
next if /\W+/;
$valid++;
$count{$_}++;
}
}
print "total things = $total, valid words = $valid\n";
foreach $word(sort keys %count) {
print "$word was seen $count{$word} times.\n";
}
执行 上面代码，我输入 ： fred \n wilma \n barney\n   然后我按CTRL-C结束, 结果是：total things = 3,  valid words = 3 \n Terminating on signal SIGINT(2) \n barney was seen 3 times  我又来了一遍结果变成了：total things = 3,  valid words = 3 \n barney was seen 3 times\n Terminating on signal SIGINT(2) \n fred was seen 3 times 这个是为什么啊？请高手指教，谢谢！

好像是CTRL-C的问题，应该按CTRL-Z+ENTER，CTRL-C是干什么的啊？

linux是向进程发送SIGTERM或SIGINT信号，强行中断程序。
