Subprocesses in Command Prompt (CMD), eg via Python subprocess.run do not maintain environment variables from the initial process ?

git config –global user.email “username@gmail.com” git config –global user.name “Forename Surname”

powercfg /batteryreport /output “%USERPROFILE%\Desktop\battery-report.html” powercfg /batteryreport /output “$env:USERPROFILE\Desktop\battery-report.html”

JavaScript scoping for let, var, const

Windows PATH

Windows PATH is an environment variable that Windows uses to look for executable code. In its purest form it is a concatenated string of different directory paths. Windows uses this as a sort of “root” directory when commands are used eg. in Command Prompt or PowerShell.

User PATH vs System PATH

Normally in Windows a user environment variable will take precedence over a sytem environment variable, but in the case of PATH the two are connected together to make the PATH variable. The user PATH is appended to the system PATH to create the PATH variable that Windows uses to look for executable code.

You can check the current value of PATH using echo %PATH% in Command Prompt and $env:Path in PowerShell

You can use the set command in Command Prompt to set environment variables for the current session eg. set PATH "%PATH%;C:\...\folder" will append the folder to PATH for this session.

It is not recommended to alter PATH permanently using the setx command, it is better done via Edit the system environment variables in Control Panel

foobar2000

foobar2000 foobar2000 /play /immediate "C:\path\to\folder\"

foobar2000 /play /immediate "C:\Users\Ben\Desktop\Core\Media\Sounds\Music\Rainy Spring Morning Ambience.opus"

You can alter settings to make it minimise to system tray “preferences/display/default user interface/background and notifications”

foobar2000.exe /play /immediate "C:\Users\Ben\Desktop\Core\Media\Sounds\Music\Rainy Spring Morning Ambience.opus" && foobar2000 /hide

/hide doesn’t seem to work with the initial run command
