Non-alphanumeric key

Hi all!

I know this isn’t strictly a Manjaro-only question, but I have a bit of a conundrum here, so I’m taking a chance.

I’ve done this a while ago, but everything seemed to be working. Today, I saw that it isn’t really. Or at least, if it is, then I don’t know how or why.

I tried adding some environment variables to /etc/environment, if this isn’t the right place, I’ll happily change it, but I put it there, so that the variables would be available to anyone using the computer. (It’s only me, but I did it this way to learn something new, to use in the future should it b e neccessary.) I used an if to check if it’s root or not, and assign the variables if it’s not.

This morning, after the update, I wanted to make sure there are no errors on boot. So, I did:

journalctl --boot --priority=3

as root.

And it gave me some HDD errors, that was caused by a faulty cable but I don’t know how to clear S.M.A.R.T. errors, or even if they can be cleared. However, I also received:

$ journalctl --boot --priority=3

pam_env(systemd-user:session): non-alphanumeric key 'if [[ $UID -eq 1000 ]];' in /etc/environment', ignoring

So it looks too me, like my if in /etc/enviroment isn’t correct.

The if statement:

## Some environment variables by Mirdarthos
if [[ $UID -eq 1000 ]];
# a Custom editor for visudo

My questions are:

  • Am I doing the check if not root correct?
    • If not, how should I change it?
    • If so, what is causing the error?
  • Anything else I need to be aware of?

I know we always say to include an inxi output here, so here is mine, althoough I have no idea what use it could possibly be:

/etc/environment can only contain variable assignments, no scripting. If you do a pacman -Fx /etc/environment you’ll see that file is owned by the package pam. The particular man page is pam_env.

This assumes bash. What I’ve done for ages is add this line to /etc/bash.bashrc. I think it came from my SuSE days, and I’ve kept using it. When I create a new system I just have to copy this one file over and use sed to add the one line to the end of the system file.

[ -f /etc/bash.bashrc.local ] && source /etc/bash.bashrc.local

And then create /etc/bash.bashrc.local where system-wide changes go. The goal is to make as few changes to installed files as possible. I always backup a file before modifying (add .install), and in many cases there are special directories for user overrides.

Just one more item, here is the arch wiki page for Environment_variables.


Thank you @stargazer!

I’ve removed the if statement part, keeping only the exports, and the error disappeared. So I’ll implement the rest of your suggestion as well.


Thanks again @stargazer, just implemented this and it works!

$ cat /etc/environment 
# This file is parsed by pam_env module
# Syntax: simple "KEY=VAL" pairs on separate lines
