linux grep 文件:这是什么意思??

你是我手中的珍宝。你是那个总给以我支持的人。所以从未察觉到自己只是愚蠢地相信你会永远在那里。但是突然又一天，我抬起头，却发现你已经悄悄走开……
IF I HAD ONLY KNOWN
Reba McEntire

If I had only known
It was the last walk in the rain
I'd keep you out for hours in the storm
I would hold your hand
Like a lifeline to my heart
Underneath the thunder we'd be warm
If I had only known
It was our last walk in the rain

If I had only known
I'd never hear your voice again
I'd memorize each thing you ever said
And on those lonely nights
I could think of them once more
Keep your words alive inside my head
If I had only know
I'd never hear your voice again

You were the treasure in my hand
You were the one who always stood beside me
So unaware I foolishly believed
That you would always be there
But then there came a day
And I turned my head and you slipped away

If I had only known
It was my last night by your side
I'd pray a miracle would stop the dawn
And when you'd smile at me
I would look into your eyes
And make sure you knew my love
For you goes on and on
If I had only known
If I had only known
The love I would've shown
If I had only known
LZ说的是这首歌吗？
