In Linux, everything is a file. Even running processes are represented as files. You will find all the running processes in /proc/, with a separate directory for each process id.
ps aux | grep [process name] # to get the process ID
cat /proc/[process ID]/environ | tr '\0' '\n'
What the above commands do, is:
- Get the id of a process by name
- print the contents of the “environ” file for that process
- print each environment variable on a new line;
trstands for “translate”
