I permanently changed my PATH variable by mistake, and I am unable to login now. How to change my PATH variable to default?
/usr/bin/sudo /bin/nano /etc/environment
Possible methods:
- 1st try to log in using a TTY (control-alt-f1).
- If that does not work boot from a live DVD.
and then use
sudo nano /etc/environment
from command line and edit out your mistake. Save and reboot to test what you did is correct.
In case you need it:
$ more /etc/environment
PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games"
