This question already has an answer here:

I'm currently exploring and experimenting with my linux just for fun and educational purposes.

I have deleted the content of the /etc/bash.bashrc and /etc/profile and I don't have any configuration in the home directory for both root and local users, I also perform a reboot.

However when i run printenv PATH the values of the path was still there which is:

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

what might be defining the $PATH?

EDIT:

I forgot to mention that I'm using Kali linux.

I've found one of the culprit is in the /etc/profile.d/kali.sh as mentioned by a guy named flyingdrifter in the comment section of this thread -> Complete view of where the PATH variable is set in bash (although his distribution is LinuxMint).

Now the $PATH variable has been reduced to

$PATH=/usr/local/bin:/usr/bin:/bin:/usr/games

which means that there are probably one last file that setting the PATH variable.

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

  • I missed the part where you didn't find any shell init files in the users homes but there are many other ways where the PATH environment variable can be set. I strongly suggest that you do more research into this to develop a better understanding before you delete files in /etc and shell init files in user's homes. A good place to start is the question in Wildcard's comment above. – Nasir Riley Aug 16 '18 at 13:50
  • @NasirRiley yeah, I found one of the culprit.. but I think there's one last file – cevhyruz Aug 16 '18 at 14:03
  • If this is a vm, be sure to take snapshots before altering things in /etc. – Nasir Riley Aug 16 '18 at 16:33

Check the /etc/login.defs and the /etc/environment as well.

More here: Complete view of where the PATH variable is set in bash

  • my /etc/environment doensn't have anything in it.. the /etc/login.def has some text.. I tried commenting out/deleting this line ``` ENV_SUPATH PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin ENV_PATH PATH=/usr/local/bin:/usr/bin:/bin:/usr/local/games:/usr/games ``` but it still have the path value – cevhyruz Aug 16 '18 at 12:42

  1. On most distributions there is something like (check your /etc/bash.bashrc and /etc/profile for code like this)

    for file in /etc/profile.d/*.sh ; do . $file ; done
    
  2. There is PAM module called pam_env (man page), which by default sets the environment variables given in /etc/environment.

    Those are specifically the files that the OP said that they cleared out. – Jeff Schaller Aug 16 '18 at 12:16
