排序数据卷号

问题描述

你能告诉我是否有一种方法可以对如下数据卷数进行排序:

想根据第一列对以下行进行排序

7.9G User1   2020-05-07     
529M User2  2020-04-24 
49M User3   2020-04-29 
43M User4   2020-04-23 
 


 

谢谢

解决方法

对于 GNU 排序,使用 sort -k1,1h file 选项:

man sort

来自-h,--human-numeric-sort compare human readable numbers (e.g.,2K 1G) -k,--key=KEYDEF sort via a key; KEYDEF gives location and type KEYDEF is F[.C][OPTS][,F[.C][OPTS]] for start and stop position,where F is a field number and C a character position in the field; both are origin 1,and the stop position defaults to the line's end.

var val = 'true';
console.log(val.trim().toLowerCase()==='true');
