我正在尝试编写一个脚本，该脚本将采用 PID 和 CPU 值，但我面临 sapce 的问题。
以下是我正在处理的日志：

在上面的日志中，我试图捕捉第一列和第三列的值。
这是我的代码：
$outval_1 是标量变量，我在某些命令的帮助下获取每一行。
my @text_words_1 = split(/\s+/, $outval_1);
#print "@text_words_1"
foreach my $val(@text_words_1)
{
if($val =~/^\s+/)
{
print "Sapce is there\n";
}
else
{
print "$val\n";
}
}
