Debian $PATH variable change

Question

How can I change the $PATH variable in Debian? I tried to change /etc/profile but this affected only normal users (and yes, I added path to BOTH user's and root's paths).

After that I tried to edit /root/.profile and then /root/.bashrc also ...

Neither worked. Do you know where could be problem?

Answer 1

This is set in the /etc/login.defs on debian 6.0 .

These are the lines you have to edit:

# *REQUIRED*  The default PATH settings, for superuser and normal users.
#
# (they are minimal, add the rest in the shell startup files)
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

I forgot to put where I found the solution: https://serverfault.com/questions/166383/how-set-path-for-all-users-in-debian

Modify /etc/environment to include a line like this:

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

Answer 3

If you are using a graphical display manager / GUI (a.k.a not just a shell or terminal) changing the /etc/profile, ~/.bashrc or other file will not change the PATH variable.

In this case you have to create the file: ~/.xsessionrc file and add something like this:

export  PATH="$PATH:/sbin"

(depending on the path you want to add)

NOTE for Debian 10, check out this solution first if you get command not found:

su - root instead of su root

Answer 4

Simple way for me was to create file /etc/default/su with content

ALWAYS_SET_PATH yes

so I do not have to meddle with system files directly.
