如何只用egrep返回部分行(How to return only part of a line with egrep)

 我有一个程序返回这样的内容： 
 

status: playing
artURL: http://beta.grooveshark.com/static/amazonart/m3510922.jpg
estimateDuration: 29400
calculatedDuration: 293000
albumName: This Is It
position: 7291.065759637188
artistName: Michael Jackson
trackNum: 13
vote: 0
albumID: 3510922
songName: Billie Jean
artistID: 39
songID: 24684170

 

 我期待从这一切中提取艺术家的名字和歌曲名称，我认为egrep会是一个很好的方式。 问题是我不知道如何只返回部分匹配行而不是整行。 
 

 egrep "artistName"显然返回 
 

artistName: Michael Jackson

 

 我只需要它回来 
 

Michael Jackson

 

 任何帮助，将不胜感激。 谢谢。 

I have a program that returns something like this:
 

status: playing
artURL: http://beta.grooveshark.com/static/amazonart/m3510922.jpg
estimateDuration: 29400
calculatedDuration: 293000
albumName: This Is It
position: 7291.065759637188
artistName: Michael Jackson
trackNum: 13
vote: 0
albumID: 3510922
songName: Billie Jean
artistID: 39
songID: 24684170

 

I'm looking to extract the artist name and the song name from all this and I figured egrep would be a nice way to do it. The problem is that I have no idea how to return only part of the matching line and not the whole line.
 

egrep "artistName" obviously returns
 

artistName: Michael Jackson

 

I only need it to return
 

Michael Jackson

 

Any help would be appreciated. Thanks.

 您可以使用display:table属性如下： 
 

#height-container{
    background:orange;
    display: table;
    vertical-align:top;
}

#left{
    display: table-cell;
    width:200px;
    background:#CD5555;
    padding:20px;
}

#right{
    width:600px;
    display: table-cell;
}

 

 勾选此http://jsfiddle.net/6rBAw/2/ 
 

 但它的工作，直到IE8及以上

    background:#CD5555;
}

#right{
    float:right;
    width:600px;
}
.clr{clear:both;}

<div id='left'>
  <div class="clr"></div>

You can use display:table property for this:
 

#height-container{
    background:orange;
    display: table;
    vertical-align:top;
}

#left{
    display: table-cell;
    width:200px;
    background:#CD5555;
    padding:20px;
}

#right{
    width:600px;
    display: table-cell;
}
