Question Problems with AWK

Hi I am writing a shell script for a number of things and aone problem that keeps comming up is AWK formatting.

When commands are typed into the command line they are fine, but when executed in the script the results are pilled up and not in a list/table format.

I have tried using awk'/$input/{print $1,$2,$...etc....
But it doesn't work, nothing happens, the code may aswell be invisible.

anyway here is the code I have written.

Code:
echo "Type in user: "
read input
echo "The last login of $input was: " `last $input | tail -10 | NEED CODE HERE FOR FORMATTING`

the result that comes out atm is:
Code:
The last login of jsk1gcc was:  jsk1gcc pts/17 192.168.***.** Tue Nov 17 09:35 - 12:13 (02:37) jsk1gcc pts/12 192.168.***.** Tue Nov 10 10:28 - 10:30 (00:02) jsk1gcc pts/14 192.168.***.**

how to I get it to do list like this this instead:
Code:
The last login of jsk1gcc was:  
jsk1gcc pts/17 192.168.***.** Tue Nov 17 09:35 - 12:13 (02:37) 
jsk1gcc pts/12 192.168.***.** Tue Nov 10 10:28 - 10:30 (00:02) 
jsk1gcc pts/14 192.168.***.** Tue Nov 10 10:22 - 12:14 (01:51)

NAME
exit, return, goto - shell built-in functions to enable the execution of the shell to advance beyond its sequence of steps SYNOPSIS
sh exit [n] return [n] csh exit [ ( expr )] goto label ksh *exit [n] *return [n] DESCRIPTION
sh exit will cause the calling shell or shell script to exit with the exit status specified by n. If n is omitted the exit status is that of the last command executed (an EOF will also cause the shell to exit.) return causes a function to exit with the return value specified by n. If n is omitted, the return status is that of the last command exe- cuted. csh exit will cause the calling shell or shell script to exit, either with the value of the status variable or with the value specified by the expression expr. The goto built-in uses a specified label as a search string amongst commands. The shell rewinds its input as much as possible and searches for a line of the form label: possibly preceded by space or tab characters. Execution continues after the indicated line. It is an error to jump to a label that occurs between a while or for built-in command and its corresponding end. ksh exit will cause the calling shell or shell script to exit with the exit status specified by n. The value will be the least significant 8 bits of the specified status. If n is omitted then the exit status is that of the last command executed. When exit occurs when executing a trap, the last command refers to the command that executed before the trap was invoked. An end-of-file will also cause the shell to exit except for a shell which has the ignoreeof option (See set below) turned on. return causes a shell function or '.' script to return to the invoking script with the return status specified by n. The value will be the least significant 8 bits of the specified status. If n is omitted then the return status is that of the last command executed. If return is invoked while not in a function or a '.' script, then it is the same as an exit. On this man page, ksh(1) commands that are preceded by one or two * (asterisks) are treated specially in the following ways: 1. Variable assignment lists preceding the command remain in effect when the command completes. 2. I/O redirections are processed after variable assignments. 3. Errors cause a script that contains them to abort. 4. Words, following a command preceded by ** that are in the format of a variable assignment, are expanded with the same rules as a vari- able assignment. This means that tilde substitution is performed after the = sign and word splitting and file name generation are not performed. ATTRIBUTES
