查找在文本文件中最长的单词 [英] Finding the longest word in a text file

问题描述

我试图让使用bash发现在文本文件中最大的字和其编号/长度的简单脚本。我知道当我用awk的简单和直接的，但我想尝试用这种方法......可以说，我知道，如果 A = wmememememe ，如果我想找到长度我可以使用回声{＃A} 的话，我会回声$ {A} 。但我想这个应用它下面

I am trying to make a a simple script of finding the largest word and its number/length in a text file using bash. I know when I use awk its simple and straight forward but I want to try and use this method...lets say I know if a=wmememememe and if I want to find the length I can use echo {#a} its word I would echo ${a}. But I want to apply it on this below

for i in `cat so.txt` do

在哪里so.txt包含的话，我希望这是有道理的。

Where so.txt contains words, I hope it makes sense.

推荐答案

通常情况下，你要使用而读循环，而不是因为我在$（猫），但因为要被拆分的所有单词，在这种情况下，它会制定出确定。

Normally, you'd want to use a while read loop instead of for i in $(cat), but since you want all the words to be split, in this case it would work out OK.

#!/bin/bash
longest=0
for word in $(<so.txt)
do
    len=${#word}
    if (( len > longest ))
    then
        longest=$len
        longword=$word
    fi
done
printf 'The longest word is %s and its length is %d.\n' "$longword" "$longest"
