Does anyone one know how to do this Unix script on a linux system?
It includes each line of the data file will contain three fields, separated by commas (¡§,¡¨). The fields are
1. The name of a new user, in the form firstname <space> lastname,
2. Either the name of a group; or the numerical Id of a group. You may distinguish between the two by
checking whether the field consists entirely of digits. For example, ¡§users¡¨ or ¡§100¡¨.
3. The full path name of the users login shell, e.g. ¡§/bin/sh".

Thanks
