I was checking environmental variables of bash process of an xterm that was started inside vnc session.
If I check the environmental variables from the bash session itself by running env or
cat /proc/pid/environ | strings, it shows all the environmental variables that would generally be set when we do su or ssh i.e., from /etc/profile and .bashrc. But when I do
cat /proc/pid/environ | strings from a putty session, it shows completely different variables.
Putting aside why only those specific variables are set, I want to know why environ of same process has different results when checked from different sessions like a double slit experiment. I understand that proc is not real filesystem. But what exactly is happening when I'm querying it and so is proc not realiable way to check remote process environment?
I wrote the question from my phone. So, I don't have any sample output to show. But, I hope you get my question.
