이러한 디렉터리 이름을 숫자로 정렬하려면 어떻게 해야 합니까?

나는 이 출력을 어떻게든 수치적으로 정렬할 수 있다는 것을 알고 있습니다(그래서 cpu1/은 cpu0/을 따릅니다)... 결국 awk를 사용하여 문자열을 다양한 방법으로 분할하여 작동하는 것을 얻을 수 있지만 이 "간단한" 접근 방식을 다음에서 재사용할 수 있습니까? 앞으로 다른 스크립트는요?

답변1

"버전 정렬"은 이 문제를 매우 잘 해결하는 것 같습니다.

for i in /sys/devices/system/cpu/cpu*/cpufreq/scaling_cur_freq; 
   do echo -n "$i: "; cat $i; done | sort -V

답변2

이것은 대부분의 경우 작동합니다유형구현:

 ... | sort -t/ -k6.4n
