sort的-r选项:sort默认的排序方式是升序,如果想改成降序,就加个-r就搞定了。 cat number.txt 1 3 5 2 4 sort number.txt 1 2 3 4 5 sort -r number.txt 5 4 3 2 1 sort的-n选项,出现10比2小的情况是由于排序程序将这些数字按字符来排序了,排序程序会先比较1和2,显然1小,所以就将10放在2前面...
sort将文件/文本的每一行作为一个单位,相互比较,比较原则是从首字符向后,依次按ASCII码值进行比较,最后将他们按升序输出。 root@[mail text]# cat sort.txt aaa:10:1.1 ccc:30:3.3 ddd:40:4.4 bbb:20:2.2 eee:50:5.5 eee:50:5.5 [root@mail text]# sort sort.txt aaa:10:1.1 bbb:20:2.2 ccc:30:...
sort用法 默认升序,即 boolcmp(inta,intb) {returna <b; } 字符串内字符按字典序排序同理(数字小于字母); 字符串数组按字符串排序则为从前往后逐个字符比较; 结构体数组 boolcmp(task a, task b) {if(a.m == b.m)returna.tb.m; //先按m降序排序,若m相同则按t升序排序; } //简便写法boolcmp(...
