You don't use $ when assigning a variable.

Code:
username=$(awk '{print "youare" $line "bond"}')

You don't need awk for this, however! Never use external utilities for things you can do with builtins, especially when processing individual lines. Running awk 9,000 times for 9,000 lines is like making 9,000 phonecalls to say 9,000 words.

You don't need another variable for this, either. I'm guessing awk got resorted to because "youare$linebond" tries to use the variable $linebond and not $line. You can surround the variable with {} brackets to prevent this.

Code:
while read line
do
        echo $line
        echo "youare${line}bond"
done</home/gunner/users.txt

NAME

       script - make record of a terminal session

SYNOPSIS

       script [-a] [filename]

DESCRIPTION

       The  script  utility  makes a record of everything printed on your screen. The record is written to filename. If no file name is given, the
       record is saved in the file typescript. See WARNINGS.

       The script command forks and creates a sub-shell, according to the value of $SHELL, and records the text from this session. The script ends
       when the forked shell exits or when Control-d is typed.

OPTIONS

       The following option is supported:

       -a    Appends the session record to filename, rather than overwriting it.

NOTES

       script places everything that appears on the screen in filename, including prompts.

ATTRIBUTES

WARNINGS

       script  can  pose  a  security risk when used in directories that are writable by other users (for example, /tmp), especially when run by a
       privileged user, that is, root. Be sure that typescript is not a link before running script.
