I have a user who have accidentally changed her user home directory to a different one, now she cannot access certain files. I am a windows admin and know not much about unix. My unix admin is on holiday and I have to look after his users. I need to change back the users directory from e.g k to b, how do I do this.

Another user cannot read certain files from a cd drive and also has a cd locked in and cannot eject the disc and.

You can see my dilema. I need answers immediately

thanks
