Ways to set $PATH

The PATH can be set in any of

   ~/.bashrc
   ~/.profile
   ~/.bash_profile
   ~/.bash_login
   /etc/profile
   /etc/environment
   /etc/bash.bashrc

Which ones are read depends on the kind of bash session you are running. What you want to do is grep for PATH in all these files.

$ grep PATH ~/.bashrc ~/.profile ~/.bash_profile ~/.bash_login \
           /etc/profile /etc/environment /etc/bash.bashrc 

I have a nifty little bash function for just this sort of issue:

grep_bash(){
 for f in  ~/.bashrc ~/.profile ~/.bash_profile ~/.bash_login \
           /etc/profile /etc/environment /etc/bash.bashrc; 
 do 
   [ -e $f ] && grep -H "$@" $f; 
 done
}

I have that in my .bashrc so whenever something strange is going on, I use it to look for the relevant string in all possible config files. For example:

$ grep_bash PATH

As a side note, not having /sbin and /usr/sbin in a normal user's PATH is standard practice for most distributions. There is no reason for a normal user to have these directories in their path. I just checked on a Debian, and Ubuntu Server and a SuSe machine and only the Ubuntu seems to add /sbin to a normal user's path and it does so in /etc/environment. The other two only add it if the user is root.
