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 risk.A debugger must be used to dump the memory where environment variables are stored. printenv2 remote-env-dump generates a shell script for that using gdb.sh <(printenv2 remote-env-string-dump) <PID> | printenv2 --by-env-string -.sudo is likely required. |
| Other | Unsupported. | Unsupported. |
TODO
- Remote mode on more OSes
