List all environment variables from the command line

Is it possible to list all environment variables from a Windows' command prompt?

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

Non expanded variables -

User variables -

reg query HKEY_CURRENT_USER\Environment

System variables -

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

Expanded variables -

In CMD -

SET

In Powershell -

Don't lose time. Search for it in the registry:

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

returns less than the SET command.

If you want to see the environment variable you just set, you need to open a new command window.

Variables set with setx variables are available in future command windows only, not in the current command window. (Setx, Examples)

To list all environment variables in PowerShell:

Get-ChildItem Env:

Or as suggested by user797717 to avoid output truncation:

Get-ChildItem Env: | Format-Table -Wrap -AutoSize

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...

Just do:

SET

You can also do SET prefix to see all variables with names starting with prefix.

For example, if you want to read only derbydb from the environment variables, do the following: 

set derby

...and you will get the following: 

DERBY_HOME=c:\Users\amro-a\Desktop\db-derby-10.10.1.1-bin\db-derby-10.10.1.1-bin

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 /?.

Simply run set from cmd.

Displays, sets, or removes environment variables. Used without parameters, set displays the current environment settings.
