When I execute:

echo $PYTHONPATH

on command line I get the following output: 

/home/nehal/catkin_ws/devel/lib/python2.7/dist-packages:/opt/ros/kinetic/lib/python2.7/dist-packages:/home/nehal/anaconda3/lib/python3.6/site-package‌​s:/home/nehal/anaconda3/lib/python3.6/dist-package‌​s:/home/nehal/anaconda3/lib/python3.6/dist-package‌​s:/home/nehal/anaconda3/lib/python3.6/dist-package‌​s:/home/nehal/anaconda3/lib/python3.5/dist-package‌​s:/home/userx/anaconda3/lib/python3.5/dist-package‌​s:/home/userx/anaconda3/lib/python3.5/dist-package‌​s:/home/userx/anaconda3/lib/python3.5/dist-package‌​s

I looked into .bashrc file and found only one PYTHONPATH set

export PYTHONPATH="/home/nehal/anaconda3/lib/python3.6/site-package‌​s:$PYTHONPATH"

I also looked into .profile, /etc/environment and /etc/profile but nowhere could I find PYTHONPATH.

My question is where did the above extra paths come from?

    There is a FILES section man bash, check it for list of files, but please note that it could change from distro to distro Commented May 8, 2018 at 18:12

    See those dist-packages, and site-packages directories? Those are probably from when you installed ros and anaconda3. Check and see what other files you are sourcing in your .bashrc Commented May 8, 2018 at 19:51
  • @nrb Is there a .bash_profile? Commented May 8, 2018 at 23:11
  • @NasirRiley No, Why? Commented May 8, 2018 at 23:26
  • @nrb Because depending on the environment, that file usually exists to initialize bash sessions as does .bashrc. Commented May 8, 2018 at 23:30

You can figure out which files are being sourced by tracing which files bash opens:

strace -e open bash -l

This should print out all the files bash tries to open (many of which are C libraries you can ingore). That should give you hints about where to look. (The "-l" option to bash asks it to run as a "login" shell, which generally causes bash to parse a few more startup files.)

On startup 'bash' loads it's settings from many files. Most of them usually live in subdirectories of '/etc' directory. So I would run the following command to find all files containing 'PYTHONPATH':

grep -R PYTHONPATH /etc 2>/dev/null
