Shell Programming and Scripting

Hello everyone,

I am trying to create a script that will make usernames (last name and first letter of name - for example, James Bond = bondj).

At this point, I figured out how to make a script that can read the list of names from a text file.

Here is what I have:

Code:

#!/bin/bash

while read user_list; do
     echo "$user_list" | tr 'A-Z' 'a-z'
done < "user_list"

The tr 'A-Z' 'a-z' minimizes the capital letters of the names to lower case so I feel I am close.

Your help would greatly be appreciated

Code:

echo "James Bond" |awk '{print tolower($2 substr($1,1,1))}'

Can you explain what that command does? During class, we never went through awk, substr, tolower, etc.

Homework?

Yes, I am doing homework, but I'm not asking for an answer.

It would be cool to receive hints and tips on what I should look into.
