awk regex problem

hi everyone

suppose my input file is
Code:
 
ABC-12345
ABCD-12345
BCD-123456

i want to search the specific pattern which looks like
Code:
[A-Z][A-Z][A-Z]-[0-9][0-9][0-9][0-9][0-9]

in a file so i used this command
Code:
cat $file | awk ' { if ($0 ~ /[A-Z][A-Z][A-Z]-[0-9][0-9][0-9][0-9][0-9]/) { print } }'

so it gives me the result as
Code:
 
ABCD-12345
BCD-12345
BCD-12345


but this is not correct i want the exact string from this
so output should be only
Code:
BCD-12345

please help me in this

SIZE(1) 						      General Commands Manual							   SIZE(1)

NAME
size - print the size of the sections in an object file SYNOPSIS
size [ option ... ] [ object ... ] DESCRIPTION
Size (without the -m option) prints the (decimal) number of bytes required by the __TEXT, __DATA and __OBJC segments. All other segments are totaled and that size is listed in the `others' column. The final two columns is the sum in decimal and hexadecimal. If no file is specified, a.out is used. The options to size(1) are: - Treat the remaining arguments as name of object files not options to size(1). -m Print the sizes of the Mach-O segments and sections as well as the total sizes of the sections in each segment and the total size of the segments in the file. -l When used with the -m option, also print the addresses and offsets of the sections and segments. -x When used with the -m option, print the values in hexadecimal (with leading 0x's) rather than decimal. -arch arch_type Specifies the architecture, arch_type, of the file for size(1) to operate on when the file is a universal file. (See arch(3) for the currently know arch_types.) The arch_type can be "all" to operate on all architectures in the file. The default is to display only the host architecture, if the file contains it; otherwise, all architectures in the file are shown. SEE ALSO
otool(1) BUGS
The size of common symbols can't be reflected in any of the numbers for relocatable object files. Apple Computer, Inc. July 28, 2005 SIZE(1)
