Bash Login tester Script help!
Hello, first of all, I am a pretty experience c++ programmer, but have never really bothered learning bash scripting at all, so I know conceptually things that can be done in c++, but I'm not too sure about bash. I'm trying to learn Bash, and wanted to start out with a practical application. So I am trying to write a script that allows me to use the "login" command in the terminal and lets me enter the login user name, and the last 3 characters (which are digits) of a password. The password consists of 5 digits, and I want the script to test the login and password of all possible combinations for the first 2 digits, like using auto-increment or something. I'm not really too sure how to approach this, any help is commended.

bashbug
BASHBUG(1) General Commands Manual BASHBUG(1)
NAME
bashbug - report a bug in bash
SYNOPSIS
bashbug [--version] [--help] [email-address]
DESCRIPTION
bashbug is a shell script to help the user compose and mail bug reports concerning bash in a standard format. bashbug invokes the editor
specified by the environment variable EDITOR on a temporary copy of the bug report format outline. The user must fill in the appropriate
fields and exit the editor. bashbug then mails the completed report to bug-bash@gnu.org, or email-address. If the report cannot be
mailed, it is saved in the file dead.bashbug in the invoking user's home directory.
The bug report format outline consists of several sections. The first section provides information about the machine, operating system,
the bash version, and the compilation environment. The second section should be filled in with a description of the bug. The third sec-
tion should be a description of how to reproduce the bug. The optional fourth section is for a proposed fix. Fixes are encouraged.
ENVIRONMENT
bashbug will utilize the following environment variables if they exist:
EDITOR Specifies the preferred editor. If EDITOR is not set, bashbug defaults to emacs.
HOME Directory in which the failed bug report is saved if the mail fails.
TMPDIR Directory in which to create temporary files and directories.
