HASHDIG-WEED(1)		     HashDig Documentation	       HASHDIG-WEED(1)

NAME
       hashdig-weed.pl - Delete	hashes from a HashDig database

SYNOPSIS
       hashdig-weed.pl [-q] [-a	hash-type] -d db -f {file|-}

DESCRIPTION
       This utility deletes specified hashes from a HashDig database that has
       been created with hashdig-make(1). Input	is expected to be plain	text
       with one	hash per line. For MD5 hash DBs, each line must	match the
       following regular expression:

	   ^[0-9a-fA-F]{32}$

       For SHA1	hash DBs, each line must match the following regular
       expression:

	   ^[0-9a-fA-F]{40}$

       For SHA256 hash DBs, each line must match the following regular
       expression:

	   ^[0-9a-fA-F]{64}$

       Input that does not match the required expression will cause the
       program to generate an error message.

OPTIONS
       -a hash-type
	   Specifies the type of hashes	that are to be deleted.	Currently, the
	   following hash types	(or algorithms)	are supported: 'MD5', 'SHA1',
	   and 'SHA256'. The default hash type is that specified by the
	   HASH_TYPE environment variable or 'MD5' if HASH_TYPE	is not set.
	   The value for this option is	not case sensitive.

       -d db
	   Specifies the name of the database to weed.

       -f {file|-}
	   Specifies the name of the input file. A value of '-'	will cause the
	   program to read from	stdin.

       -q  Don't report	errors (i.e., be quiet)	while processing input.
