Mac hardware and system information retrieval one-liner

#shell #mac #bash #webdev
  • When I use Mac, there are times when I want to get system information and so on by command.
  • Also, you may want to use that information in shellscript.
  • In this article, we will write commands to obtain hardware and system information from your Mac.

Result

  • Here are the results.
  • Enter each command based on the information you want to retrieve.

Model Name 

# model name # output : MacBook Pro** info=$(system_profiler SPHardwareDataType | grep 'Model Identifier'); echo "${info#*: }"
Enter fullscreen mode Exit fullscreen mode

Processor 

# processor # output : Dual-Core Intel ** info=$(system_profiler SPHardwareDataType | grep 'Processor Name'); echo "${info#*: }"
Enter fullscreen mode Exit fullscreen mode

Core 

# core # output : 2 info=$(system_profiler SPHardwareDataType | grep 'Cores'); echo "${info#*: }"
Enter fullscreen mode Exit fullscreen mode

Serial Number 

# serial number # output : ***** info=$(system_profiler SPHardwareDataType | grep 'Serial Number'); echo "${info#*: }"
Enter fullscreen mode Exit fullscreen mode

UUID 

# UUID # output : *****-*****-**** info=$(system_profiler SPHardwareDataType | grep 'UUID'); echo "${info#*: }"
Enter fullscreen mode Exit fullscreen mode

Memory 

# memory information # output : ** GB info=$(system_profiler SPHardwareDataType | grep 'Memory'); echo "${info#*: }"
Enter fullscreen mode Exit fullscreen mode

User 

# user information # output : **** *** (*******) info=$(system_profiler SPSoftwareDataType | grep 'User Name'); echo "${info#*: }"
Enter fullscreen mode Exit fullscreen mode

Supplement

  • For ease of use, the fetched content only outputs the results.
  • Use shall be in the following format.
    • info=$(system_profiler data-type-name | grep 'field-name'); echo "${info#*: }"
  • The above data-type-name and field-names are confirmed by the following command.
    • data-type-name : system_profiler -listDataTypes
    • field-name : system_profiler data-type-name
  • Other information that can be obtained with system_profiler can be found here.
