Deleting row if all column values are a particular string

Hello,

I have a very large file for which I would like to remove all rows for which the value of columns 2-5 is zero.

For instance I would like this file:
Code:
contig1, 0, 0, 0, 0 
contig2, 1, 3, 5, 0 
contig3, 0, 0, 0, 0 
contig4, 0, 5, 6, 7

To become this file:
Code:
contig2, 1, 3, 5,0 
contig4, 0, 5, 6, 7

I'm aware that you can use 'Awk' to remove rows for which a particular column has a specific value, but I can't seem to figure out how to remove a row if multiple columns have to have a particular value (i.e zero).

Thanks!

NAME
Locale::Codes::LangFam - standard codes for language extension identification SYNOPSIS
use Locale::Codes::LangFam; $lext = code2langfam('apa'); # $lext gets 'Apache languages' $code = langfam2code('Apache languages'); # $code gets 'apa' @codes = all_langfam_codes(); @names = all_langfam_names(); DESCRIPTION
The "Locale::Codes::LangFam" module provides access to standard codes used for identifying language families, such as those as defined in ISO 639-5. Most of the routines take an optional additional argument which specifies the code set to use. If not specified, the default ISO 639-5 language family codes will be used. SUPPORTED CODE SETS
There are several different code sets you can use for identifying language families. A code set may be specified using either a name, or a constant that is automatically exported by this module. For example, the two are equivalent: $lext = code2langfam('apa','alpha'); $lext = code2langfam('apa',LOCALE_LANGFAM_ALPHA); The codesets currently supported are: alpha This is the set of three-letter (lowercase) codes from ISO 639-5 such as 'apa' for Apache languages. This is the default code set. ROUTINES
