List all environment variables from command line?

Question

I'd like to know if it's possible to list ALL environment variables from Windows' Command Prompt.

Something equivalent to PowerShell's gci env: (or ls env: or dir env:).

Answer 1

Jon has the right answer, but to elaborate a little more with some syntactic sugar..

SET | more

enables you to see the variables one page at a time, rather than the whole lot, or

SET > output.txt

sends the output to a file output.txt which you can open in notepad or whatever...

Answer 2

don't lose time to search it in registry

reg query "HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Environment"

returns less then set command

Answer 3

You can use SET in cmd

To show the current variable, just SET is enough

To show certain variable such as 'PATH', use SET PATH.

For help, type set /?.
