Where are the files for System Information?

Question
I'm just curious if anyone knows where I can find the files that feed the data into the System Information Application (ATA, Audio, etc).
I am interested in writing a program that sends an email every time the battery cycle count increases.
Thanks.
Solution
System Information is a GUI for the CLI system_profiler. It's read directly from whatever system_profiler
spits out. All the work is already done for you (system_profiler
reads from many different files and executables):
!Just saw an answer posted. See @XAleXOwnZX for the exact command.
To compile that into a script within Terminal, enter text as follows. Return is supported for newlines after cat
command.
njboot$ cat > cycle
#! /bin/bash
#Output is current cycle count of the battery
system_profiler SPPowerDataType | grep "Cycle Count" | awk '{print $3}'
Now, you have the script. Press Control+D within terminal for a carriage return:
Make executable:
njboot$ chmod +x cycle
- Test:
njboot$ ./cycle
64
- Move into your local bin, if it's included in your shell path. The file currently resides in your top user directory ~/
Optional:
njboot$ mv cycle ~/bin/
- Now it runs directly!
njboot$ cycle
64
Addendum: Again, credit to XAleXOwnZX for the exact command
njboot$ cat > cycle
#! /bin/bash
#Cycle Count of Battery
system_profiler SPPowerDataType | grep "Cycle Count" | awk '{print $3}'
njboot$ chmod +x cycle
njboot$ ./cycle
64
njboot$ mv cycle ~/bin/
njboot$ cycle
64
OTHER TIPS
I don't know the file per-say, but you can use a simple shell script to get the battery cycle count, as seen here.
system_profiler SPPowerDataType | grep "Cycle Count" | awk '{print $3}'
