Remove path from $PATH

Question

I'm newbie here and unknowingly i added some un necessary paths (like 2 times java ) to

$PATH

I tried many solution but they remove until i'm active. If i reboot last path comes again. /usr/lib/jvm/java-13-oracle/db/bin

Here is my output

/home/nikhil/anaconda3/bin:/home/nikhil/anaconda3/condabin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin:/usr/lib/jvm/java-13-oracle/bin:/usr/lib/jvm/java-13-oracle/db/bin

How to remove that permanently. Even i log out or reboot or shut down. I'm on ubuntu 18.04.

This is my etc/env...

PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games"

There are many places you could have added it - it's hard for us to guess which file(s) you edited (/etc/environment/? /etc/profile? ~/.bashrc?) — steeldriver, Feb 25 '20 at 15:37
@steeldriver I have checked all above. None of these seems wrong. — Nikhil Badyal, Feb 25 '20 at 15:45
Create new user: sudo adduser user, login as it using sudo user command and echo $PATH from it in your question. — Gryu, Feb 25 '20 at 15:49
@Gryu I did as you said. But i got same output. 2 times in new user. — Nikhil Badyal, Feb 25 '20 at 15:57
@Gryu 1st path was not there(anaconda) only java was there in new user. — Nikhil Badyal, Feb 25 '20 at 15:59
@NikhilSharma Ok, this means, you've changed something in your system's environment. What is at the end of your bash.bashrc cat /etc/bash.bashrc? — Gryu, Feb 25 '20 at 16:00
Ok, there's nothing. You could remove it from question as it is not messed up. You could also check what is in your crontab: crontab -e and sudo crontab -e — Gryu, Feb 25 '20 at 16:08
Another place to check is any .sh files that might have been sourced from the /etc/profile.d directory ex. grep -w 'PATH' /etc/profile.d/*.sh — steeldriver, Feb 25 '20 at 16:10
@steeldriver After running above command i got this # Expand $PATH to include the directory where snappy applications go. /etc/profile.d/apps-bin-path.sh:if [ -n "${PATH##*${snap_bin_path}}" -a -n "${PATH##*${snap_bin_path}:*}" ]; then /etc/profile.d/apps-bin-path.sh: export PATH=$PATH:${snap_bin_path} /etc/profile.d/jdk.sh:export PATH=$PATH:/usr/lib/jvm/java-13-oracle/bin:/usr/lib/jvm/java-13-oracle/db/bin — Nikhil Badyal, Feb 25 '20 at 16:15
Any of (1) edit the file and comment out or delete the erroneous assignment (2) rename the file with a different extension such as .ignore or (3) delete the file. Which one is right for your situation is for you to decide. — steeldriver, Feb 25 '20 at 16:45
@steeldriver Unable to any of these. Delete and rename option not available. Cant open it so no edit — Nikhil Badyal, Feb 25 '20 at 17:02
@NikhilSharma How do I get permissions to edit system configuration files? — steeldriver, Feb 25 '20 at 17:05
@steeldriver Even after doing as you said. Nothing happened. :-( — Nikhil Badyal, Feb 25 '20 at 18:14
@Gryu I did something and found that on creating new user. Java path is not in path. It means that is not in enviornment. What i should do now ? — Nikhil Badyal, Feb 25 '20 at 18:30
@NikhilSharma after changing files in /etc/profile.d, you will need to log out or at least start a new login session (ex. su -l username) for the changes to take effect — steeldriver, Feb 25 '20 at 19:39

To find all files with /usr/lib/jvm/java-13-oracle/bin text in your / directory, execute the next command:

sudo grep -rl "/usr/lib/jvm/java-13-oracle/bin" /

To reduce searching time, you could replace / by /etc, then by /home/youruserfolder

Then you could check suspicious files, trying to comment those, where export PATH=$PATH:/usr/lib/jvm/java-13-oracle/bin or something similar is present.
