Hi ALUG,
Is it possible to query the environment variables being used by a specific process; from the outside?
Specifically, I want to know if a running Apache has a particular environment variable set.
Best, Richard

sudo cat /proc/<pid>/environ | tr '\0' '\n'
Should do what you want.
Richard,
You should be able to look in /etc/$PID/environ to find the environment variables available.
Beware - this file will prolly contain special chars which may break your terminal session display...
HTH,
