Cross-platform

Installation

via package managers:
- Arch Linux: paru -S printenv2
via Cargo: Run cargo install printenv2 if you already have Rust development environment setup.

Notes on remote mode

printenv2 comes with the ability to read environment variables of another running process. However, mileage varies depending on the operating system.

The following table shows how each platform is supported.

Platform	Environment variables at startup	Environment variables in present
Linux	`printenv2 --by-env-string /proc/<PID>/environ`.`sudo` for processes you don't own.	Use at your own risk.A debugger must be used to dump the memory where environment variables are stored. `printenv2 remote-env-string-dump` generates a shell script for that using `gdb`.`sh <(printenv2 remote-env-string-dump <PID>) \| printenv2 --by-env-string -`.`sudo` is likely required.
Windows	Unsupported.	Use at your own risk.Using undocumented APIs to dump the memory where environment variables are stored.`printenv2 remote-env-string-dump <PID> \| printenv2 --by-env-string -`
Other	Unsupported.	Unsupported.

TODO
