Script for Drive Temperature

[map2k13]

Hello, I've scoured the web and cannot find a good app showing SMART information about my external drive temperature in the menu bar.

Using homebrew's smartctrl, I can get a script to output the drive temp in TERMINAL only. the variable just wont show up in SwiftBar unfortunately.

Here is my script:

Script:
#!/bin/bash

#Fetch SMART data for the drive
smart_output=$(smartctl -A /dev/disk4)

#Extract specific columns for drive temperature (ID#194) and extract the numerical temperature value
drive_temp_info=$(echo "$smart_output" | awk '$1==194 {print $10}')

#Output the integer temperature to ensure it's correctly formatted
echo "MediaX1: ${drive_temp_info}°C"

Terminal output of script: MediaX1: 41°C

Swiftbar output: MediaX1: °C

Here is my smartctl output:

smartctl 7.4 2023-08-01 r5530 [Darwin 23.4.0 arm64] (local build)
