Como eu classificaria esses nomes de diretório numericamente?

Question

Estou ciente de que eu posso de alguma forma classificar esta saída numericamente (assim cpu1 / segue cpu0 /) ... Eu provavelmente poderia ter algo para trabalhar, eventualmente, dividindo a cadeia de várias maneiras com o awk, mas existe um "fácil "maneira que seria um pouco reutilizável no futuro em outros scripts?

Answer 1

A "classificação de versão" parece funcionar bem com isso.

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

    

Answer 2

Isso deve funcionar com a maioria das implementações sort :

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

Tentando dar um exemplo (não consigo encontrar o cpufreq nos sistemas aos quais tenho acesso ...):

arquivo de entrada

/sys/devices/system/cpu/cpu0/cpufreq/scaling_cur_freq: 2395000
/sys/devices/system/cpu/cpu10/cpufreq/scaling_cur_freq: 1064000
/sys/devices/system/cpu/cpu11/cpufreq/scaling_cur_freq: 1064000
/sys/devices/system/cpu/cpu12/cpufreq/scaling_cur_freq: 1064000

/sys/devices/system/cpu/cpu20/cpufreq/scaling_cur_freq: 1064000
