Sort characters in length

http://bbs.chinaunix.net/thread-594724-1-1.html

awk '{print  length($0),$0}' file |sort -nr|sed '/^[^ ]* /s///'

如何对列表按字符长度排序
/^[^ ]* /匹配n个不是空格的字符然后是一个空格，也就是第一列
/^[^ ]* /s// 替代匹配的内容
//新内容是null

有时间看看那篇 sed1line

## 方法2
while read line;do
        echo -n "$line ";expr length $line
done<filename|sort -k2nr|cut -f1 -d' '
