MAKE_SHA1(8)							  MAKE_SHA1(8)

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 configu‐
	      ration 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	 argu‐
	      ments.

       -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.
