Quale comando o programma del terminale è in grado di elencare le ore di accensione di un SSD?

6

Sto cercando di utilizzare lo shell unix per recuperare i dati SSD (e HDD) mostrati dall'utilità del disco nella finestra delle informazioni.

SonoimmediatamenteinteressatoalPowerOnHoursealPowerCycle,masetuttiidatiprovengonodaunastrutturadatiounostrumento,tantomeglio.Isolitistrumentidiskutilinfodisk0eioreg-lnonproduconoivalori"di interesse" elencati nella schermata qui sopra.

Questa informazione è disponibile da uno qualsiasi degli strumenti di terminale OS X o ho bisogno di localizzare un pacchetto open-source che faccia le stesse chiamate API per ottenere questo livello di dettaglio su un drive Mac?

smartmontools è un pacchetto open source che fornisce la maggior parte dei valori a cui sei interessato.

Scaricalo dal link e compila come al solito:

$ cd smartmontools-6.0
$ ./configure 
$ make
$ sudo make install

(Se preferisci, installalo con MacPorts o Fink .)

Se non diversamente specificato come opzione per ./configure , smartmontools comandi installa in /usr/local/sbin , quindi aggiorna la variabile $PATH se necessario.

Lo strumento a cui siamo interessati è chiamato smartctl .

Prima attiva S.M.A.R.T.:

$ /usr/local/sbin/smartctl /dev/disk0 -s on

Quindi eseguilo:

$ /usr/local/sbin/smartctl /dev/disk0 -x

Questo è un estratto dell'output, che fornisce una grande quantità di informazioni. I valori per Power_On_Hours e Power_Cycle_Count sotto corrispondono (una volta convertiti da decimale a esadecimale) quelli indicati da Utility Disco.

Che ne dici di utilizzare il comando built-in system_profiler ?

system_profiler -listDataTypes
system_profiler SPSerialATADataType
system_profiler -xml SPSerialATADataType
