hey guys
I would really appreciate some help, i need to do a project for a job that requires minimal UNIX scripting and im REALLY stuck
basically Im stuck at what i believe is something really simple but i just dont have a clue how to do it efficiently and properly and i REALLY appreciate some help
Basically i have a loop at which someone has to enter a string of 3 numbers.
-I want the code to check that the string is numbers only
-check that the numbers have not been already signed to someone else in the users.db file
-restrict the number of numbers to only 3.
- each time the user inputs the number wrong i want it to be allowed to correct and tell why he has to re enter it.
This is the best i could came up with but IM REALLY suck and im at a short UNIX course (1 week) for a job....
Can anyone please tell how do i make the loop properly??
this is the best i could came up with... and i KNOW is crap... but i just dont know best........ I would really appreciate some guidance plz
