Changing Environment variables

Hi
trying to troubleshoot an application not launching(Houdini) so ruling out possible causes.

When I observe my $PATH variables I get

/usr/local/bin:/usr/bin:/bin:/usr/local/sbin:/usr/sbin:/home/foo/.local/bin:/home/foo/bin

Does that look correct?

Confused by the documentation to change or update yout PATH vars.
http://centoshowtos.org/environment-variables/

To make them permanent it says you must add an entry in /etc/profile.d

Fine, but in that folder are a bunch of .sh files.
How would you edit the EXISTING PATH vars?

To add to the PATH:

Code:

PATH='$PATH:/directory'

Yes. Your path looks correct. To make them permanent for one user, you can edit their /home/username/.bash_profile or .bashrc to have your changes:

Code:

# .bash_profile or .bashrc
export PATH="${PATH}:/your/new/path:/another/new/path

To make them permanent for the whole system and all users, you can add/edit the same in either /etc/bashrc or /etc/profile

Usually environment stuff like PATH goes in /etc/profile
