Polling S.M.A.R.T. Status

Scripting Forums AppleScript | Mac OS X

Is it possible to poll S.M.A.R.T. Status using AppleScript/OSAX/Automator?

#2

I don’t know much about Automator (yet), but it’s fairly easy to check the SMART status:

set status to do shell script “diskutil info disk0 | grep SMART”
– " SMART Status: Verified"

or, for a more concise result:

– set status to do shell script “diskutil info disk0 | grep SMART | cut -d : -f 2 | sed s/’ ‘/’'/g”
– “Verified”

#3

Or for the “sed dislexic” (moi) this:

set status to last word of (do shell script "diskutil info disk0 | grep SMART") --> "Verified"
#4

Or, since the SMART status of a disk might consist of more than one word (such as “About to Fail” or “Not Supported”), perhaps:

text from word 3 to -1 of (do shell script "diskutil info disk0 | grep SMART")
#5

Good catch. I’ve never had one fail, so I didn’t know what they said then.

#6

Is it possible to write the log file to the desktop, giving it the name of the SMART status?

Example (but naming the text file with the SMART status):

do shell script "sudo diskutil info disk0 | grep SMART > ~/Desktop/SMART.txt"
#7

You don’t need ‘sudo’, but you do need single quotes for a name with a space in it:

do shell script "diskutil info disk0 | grep SMART > ~/Desktop/'SMART status.txt'"
#8

Thanks but you misunderstood my request. I’m looking to output the log file to desktop but naming it the current status of the drive:

set status to text from word 3 to -1 of (do shell script "diskutil info disk0 | grep SMART > ~/Desktop/' & status & '.txt'")

Thanks

Gotcha;

I don’t know how to do it within the shell script, but this does it:


set status to text from word 3 to -1 of (do shell script "diskutil info disk0 | grep SMART")
try
	set f to open for access ((path to desktop as text) & status) with write permission
	close access f
on error -- just in case SMART doesn't answer
	close access f
end try
#10

That’s what I need! Thanks.

#11

just so you know for reference.

set status to text from word 3 to -1 of (do shell script "diskutil info disk0 | grep SMART")
do shell script "touch  ~/Desktop/" & status & ".txt"

You can also use the unix equivalent of set status to.

status= command here; next command

note the backticks ` the ; makes sure the first command is completed before the next one starts

To call the variable back using $status note the $ dollar sign

This works but it makes the whole line the file name.

do shell script "status=`diskutil info disk0 | grep SMART`; > ~/Desktop/$status.txt"

And this just gives the last word,

do shell script "status=`diskutil info disk0 | grep SMART |awk 'BEGIN { FS=" & "\" \" " & "  ;}  {" & " " & " printf(  $3 ); }'`; > ~/Desktop/$status.txt"

I’m not sure how to make it variable depending on the output.
