Hi Jon

I have tried to add the following command path as it was showing a different path for me.

export PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/X11R6/bin

it works for the current terminal window where export path is added. but, when restarted, it still doesn't work. I have tried the "bash -l" to effectively run it in bash. when doing so, it reverts to the original form of the above problem.

I have tried to edit the vi ~/.bashrc but i am unable to open this file. Any idea please??

thanks and eagerly anticipating for your reply.

Also any help from anybody is much appreciated.

thanks

The default path variable for all users is set in /etc/enviroment. You can try to edit it my doing the following:

sudo nano /etc/enviroment

make sure the first line reads something like:
PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games"

Also, what error does it give you when you try to open ~/.bashrc?
