根据字符串长度排序

galeki posted @ 2008年12月07日 02:09 in Bash 和它的朋友们 with tags 排序 bash , 6075 阅读

sort 命令可以按照字母或者数字顺序排列字符串,不过如果我们想根据字符串的长度来排序呢?

配合一点点 awk 魔法,就可以达成愿望。建立一个 lsort 文件,内容如下:

#! /bin/sh
awk 'BEGIN { FS=RS } { print length, $0}' $* |
sort +0n -1 |
sed 's/^[0-9][0-9]* //'

首先,awk 把标准输入中每行的前面,都加上这行的长度,然后传给 sort 对长度数字进行排序,最后用 sed 把长度数字删掉。

保存之后,加上可执行标记,就可以拷贝到 /usr/bin 之下,来使用了。

比如,我想看看以 a 开头的最长的单词是哪个,那么输入:

$  look a | lsort

look a 会将所有 a 大头的单词按照字幕顺序显示出来,经过 lsort 的过滤,最后的就是最长的单词了:

...
appendorontgenography
anatomicophysiological
aquopentamminecobaltic
anthropomorphologically
$

字符串也可以是数字开头,需要修正一下:)

数字开头没问题,用 cut -d' ' -f2- 代替后面那个 sed 也可以。
