List all environment variables from the command line

Question

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

Something equivalent to PowerShell\'s gci env: (or ls e

Answer 1

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)

Answer 2

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 3

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

Answer 4

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.

Answer 5

As mentioned in other answers, you can use set to list all the environment variables or use

set [environment_variable] to get a specific variable with its value.

set [environment_variable]= can be used to remove a variable from the workspace.

Answer 6

Simply run set from cmd.

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