一、首先考虑用到grep 二、排序sort(这里排序是为了后面好去重) 三、去重并计算单词出现次数 四、再sort排序(-nr表示按数值进行降序排序) 五、再通过awk控制输出方式 法二:tr 法三:awk 回到顶部 192. Word Frequency Write a bash script to calculate the frequency of each word in a text filewords.txt. ...
Your script should output the following, sorted by descending frequency: the 4 is 3 sunny 2 day 1 1. 2. 3. 4. Note: Don't worry about handling ties, it is guaranteed that each word's frequency count is unique. Could you write it in one-line using Unix pipes? 1. 2. 解题思路 见...
