I can’t make any of the commands work, they all say they aren’t found. I’ve googled around a fair bit, and I keep seeing I need to change my PATH variables, but I don’t know what to!!
So ls, su, and yast2 don’t work when I type them in by themselves ie:
reuben@linux-qgyq:~> yast2
bash: yast2: command not found
Yes, but not having ls or su in one’s path is pretty bad, as they are both in /bin so the OP must have messed things up. Probably in trying to get yast2.
