haha thx it works!! but it show one show chunk of inputs in a line but included all the list of stocks which even has more than 3.
I thought that after cutting the amount and display, everything will be less than 3.

Ok I done another way using awk.
It will print for the first field name and the fourth field which is the stock.
I know something wrong with the $4<3.
Anyone can enlighten me?
All the script want is to print anything that has less than 3.

Code:
{  
    awk -F: '{printf "%-1s,%-10s\n", $1, $4<3}' stockDB.txt
}

color.4th

COLOR.4TH(8)						    BSD System Manager's Manual 					      COLOR.4TH(8)

NAME

     color.4th -- FreeBSD color-detection boot module

DESCRIPTION

     The file that goes by the name of color.4th is a set of commands designed to simplify color logic.  The commands of color.4th by themselves
     are not enough for most uses.  Please refer to the examples below for the most common situations, and to loader(8) for additional commands.

     Before using any of the commands provided in color.4th, it must be included through the command:

	   include color.4th

     This line is present in /boot/loader.4th file, so it is not needed (and should not be re-issued) in a normal setup.

     The commands provided by it are:

	   loader_color?	  Returns FALSE if the loader_color environment variable is set to ``NO'' (case-insensitive) or ``0''.	Otherwise
				  returns TRUE (unless booting serial).

     The environment variables that effect its behavior are:

	   loader_color
		     If set to ``NO'' (case-insensitive) or ``0'', causes loader_color? to return FALSE, indicating to many modules that color
		     should not be used.

FILES

     /boot/loader      The loader(8).
     /boot/color.4th   color.4th itself.
     /boot/loader.rc   loader(8) bootstrapping script.

EXAMPLES

     Standard i386 /boot/loader.rc:

     Use color where applicable:

	   loader_color="YES"

SEE ALSO

     loader.conf(5), loader(8), loader.4th(8)

HISTORY

     The color.4th set of commands first appeared in FreeBSD 9.0.

AUTHORS

     The color.4th set of commands was written by Devin Teske <dteske@FreeBSD.org>.
