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

IGAWK(1)							 Utility Commands							  IGAWK(1)

NAME

       igawk - gawk with include files

SYNOPSIS

       igawk [ all gawk options ] -f program-file [ -- ] file ...
       igawk [ all gawk options ] [ -- ] program-text file ...

DESCRIPTION

       Igawk is a simple shell script that adds the ability to have ``include files'' to gawk(1).

       AWK programs for igawk are the same as for gawk, except that, in addition, you may have lines like

	      @include getopt.awk

       in your program to include the file getopt.awk from either the current directory or one of the other directories in the search path.

OPTIONS

       See gawk(1) for a full description of the AWK language and the options that gawk supports.

EXAMPLES

       cat << EOF > test.awk
       @include getopt.awk

       BEGIN {
	    while (getopt(ARGC, ARGV, "am:q") != -1)
		 ...
       }
       EOF

       igawk -f test.awk
