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

It is expecting 1+4 characters and followed by hypen(-) and 5 numbers

[^A-Z][A-Z]\{4\}
