NAME

       make_sha1 - Generate SHA1 checksums for given set of users.

SYNOPSIS

       make_sha1 [ -C config-file ] [ -D md5_dir ] [ -k count ] [ -f input_file ] [ -m offset ] [ -M modulo ] [ -v ] [ userid...  ]

DESCRIPTION

       Generate  SHA1  checksums  for  messages  given	set  of  users.  Works as incremental update: reads in existing set of SHA1 checksums from
       sha1_dir/u/userid (hashed on first letter of userid) if that file exists. Scans account looking for new messages, and then updates record.

       The SHA1 checksums which are generated are used to test integrity of the master, replica and backup systems on Hermes.

OPTIONS

       -C config-file
	      Read configuration options from config-file.

       -D sha1_dir
	      Read and write SHA1 checksums from sha1_dir, overrides configuration file setting of the same name.

       -k count
	      Concurrency level: run up to count asynchronous child processes.

       -f input_file
	      List of accounts to process: use in place of command line arguments.

       -m offset
	      Regenerate given fraction of the user database in combination with -M below.

       -M modulo
	      Regenerate SHA1 checksums for given fraction of user database. Allows for rolling consisency checks.

       -v     Verbose mode.
