今天能写出这样一个shell脚本，其实并没有费太大力气，因此并不是说我几经周折终有结果而兴奋，而是觉得自己现在终于可以踏实下来做自己喜欢做的事情，能够专注的去学该学的东西而兴奋。之前学了很多杂七杂八的东西，因为目标不明确，很痛苦，究其根本，是因为不知道自己将从事什么职业，只知道自己想从事IT这行，但具体的工作方向却不知道，因此啥都要学习，这个过程对于我来说很痛苦。因为我是一个比较喜欢踏踏实实做事的人，不做就不做，做就要做得很好。我之前看过一篇关于论述程序员浮躁的文章，写得太精彩了。而里面提到的很多浮躁的做法都在我身上得到了印证，这让我很郁闷。现在，工作定了，我知道该学点啥了，目标专注了，太美好了。

借用Steven Jobs的一番话来说就是：

The only way to be truely satisfied is to do what you believe is great work, and the only way to do great work is to love what you do!

我觉得一个人能做到这一步，真的很幸福，自己去努力，去拼搏，去实现自己的价值，让自己对自己的表现满意，这是我经常对自己说的一句话。

现在的我，工作定了，女友也定了，也就是媳妇定了，我需要做的就是去奋斗，去努力，去拼搏。

我很感谢自己能遇到这样一个媳妇，能支持我，关心我，我不知道自己今后会不会很成功，但是我知道有了这个好内柱，我做什么都踏实。我知道，有了她，我太幸福，我也一定会带给她幸福的，I promise!

好了，下面就把代码贴出来吧，呵呵：

#!/bin/sh

cd /hadoop/logs

var="`ls *.log`"
cur=""
name=""
file=log_name.txt

if [ -e $file ]; then
 rm $file
fi

for cur in $var
do
 name=`echo $cur | cut -d'-' -f3`
 
 #cat $cur | grep ^2008 | awk '{print $0 " [`echo $name`]"}' >> $file
 cat $cur | grep ^2008 | sed "s/^.*$/&[$name]/" >> $file
 #awk '{print $0 " [`echo $name`]"}' >> $file
done

cp $file __temp.txt
sort __temp.txt >$file
rm __temp.txt

运行的结果是：
