When you log in and start bash as a login shell (bash -l) these scripts will be read:
System wide:
- /etc/profile
(This one should be shell independent, since it may also be called from ksh, sh, etc etc).
- /etc/bashrc/
Personal:
- ~/.profile
- ~/.bash_profile (this one might actually source the .bashrc file)
- ~/.bashrc
Decide if you want to make system wide, or user only changes. Then look for these files and select one of them. Add the path changes and start a new shell. Test. If it does not work, close the shell (with logout or Controld) and correct the typo.
Note that I did not write 'log out and start a new shell'.
