I am using fish shell on a Ubuntu sytem. This question is about redundancy in $PATH that I am setting unintentionally.
When I type echo $PATH, I get:
/opt/anaconda3/bin/ /opt/anaconda3/etc/fish/conf.d/ /opt/anaconda3/bin/ /opt/anaconda3/etc/fish/conf.d/ /usr/local/sbin /usr/local/bin /usr/sbin /usr/bin /sbin /bin /usr/games /usr/local/games .
Multiple annoyances with this: /opt/anaconda3/bin showing up twice, showing some non-existant directories: /usr/local/games /usr/games.
My /etc/login.defs reads:
ENV_PATH PATH=/usr/local/bin:/usr/bin:/bin
So the redundancy is not coming from there. Of course, my PATH in config.fish is set as:
set -gx PATH /opt/anaconda3/bin/ (/opt/anaconda3/bin/conda info --root)/etc/fish/conf.d/ $PATH .
My Question: where does fish get its PATH from, other than what is set in my environment and what is handed to it by: /etc/login.defs?
UPDATE: I changed to using fish_user_paths variable, per documentation which got rid of /opt/anaconda3/bin added twice. Still the /usr/games/ and /usr/local/games are getting added automagically (and those directories don't exist on my system!).
After looking around on the Internet, this is not a shell related issue: fish shell or any other shell. It's a Linux issue. The kernel, somewhere before forking the init, reads the: /etc/environment file and sets the system wide default path.
In a single user environment, we could just edit that file - if we insist. Personally, I added lines to my fish profile to purge the non-existant directories from the path :
if set -l index (contains -i -- /usr/local/games $PATH)
set --erase PATH[$index]
end
if set -l index (contains -i -- /usr/games $PATH)
set --erase PATH[$index]
end
