List all environment variables from the command line – Dev

The best answers to the question “List all environment variables from the command line” in the category Dev.

QUESTION:

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:).

ANSWER:

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:

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

ANSWER:

Simply run set from cmd.

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

ANSWER:

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
