How to find the source definition of an environment variable?
There is a global environment variable that was declared somewhere in my OS. Let's say is called FOOBAR
When I echo it, I receive a proper output:
$ echo $FOOBAR
localhost%6200
I want to know where is defined because I need to update its value for certain process. Currently, I am declaring this value manually in a script before executing my processes, just to override it:
#!/bin/sh
# other comands...
export FOOBAR=localhost%16200
# rest of script
Still, I'm curious about why I cannot find the definition of this variable.
I have gone through several posts like these:
How to permanently set environmental variables (trying to see other places where to find the environment variable)- How do I find all files containing specific text on Linux?
- How to determine where an environment variable came from?
I've looked into ~/.bashrc, /etc/profile, scripts in /etc/profile.d/, I've executed several commands and tried different variations, like searching in all /etc and /home/MyUser and still no luck.
The only hint I got is this output from searching through /home/MyUser:
$ find /home/MyUser -type f -exec grep -F FOOBAR {} +
... lines ...
/home/MyUser/.xsession-errors:dbus-update-activation-environment: setting FOOBAR=localhost%6200
Then I tried looking at the variables defined for dbus by using this command
$ systemctl --user show-environment
... among other variables ...
FOOBAR=localhost%6200
There I see it!
How can I track this environment variable definition?
command-line bash environment-variables
