- REHASH
- v1.10

- by Tom Collins
-
- What
- ----
-
- REHASH is a small RBBS utility for packing and resizing a system's
- users files. Users can be removed based on the date last on the
- system (or in a conference), and exempted by security level.
-
- Why
- ---
-
- Ideally, you'd set up your BBS with an optimum number of user records
- for both the main board and for conferences. Determining the optimum
- is at best, an annoying problem. REHASH takes care of this for you.
- In addition, the users' file "rebuilding" function, normally contained
- within CONFIG, can be done by REHASH from a batch file on a regular
- basis.
-
- Using It
- --------
-
- The generic form of the REHASH command line is:
-
- REHASH <Messages File> <Users File> [/ELx] [/OTy] [/MFz] [/EUm]
-
- The first two parameters are required, and correspond to a set of
- messages/users files. For example, MESSAGES and USERS, or
- TREKM.DEF and TREKU.DEF.
-
- The /OT parameter tells REHASH to delete users who haven't been on
- (or entered a given conference) in y days. The default is to not
- delete any users.
-
- The /EL parameter tells REHASH to never delete users whose security
- level is greater than or equal to x.
-
- The /MF parameter forces REHASH to make the users file size at
- least z times the required size. So, if the users file requires
- space for 100 users, using /MF1.5 causes REHASH to make the file at
- least 150 records.
-
- The /EU parameter tells REHASH to leave room for at least m more
- users than is required.
-
- /EU and /MF can be used together.
-
- If /MF and /EU are omitted, REHASH will leave room for at least 8
- additional users (equivalent to /EU8).
-
- Examples
- --------
-
- a. REHASH MainM.DEF MainU.DEF /OT60 /EL10
-
- Delete users from the main board who haven't been on in two
- months (and whose security level is less than 10)
-
- b. REHASH TrekM.DEF TrekU.DEF
-
- Resize the users file to whatever is necessary, and leave
- all user records intact.
-
- c. REHASH SysopM.DEF SysopU.DEF /EU2
-
- Leave all users intact, and only leave room for two additional
- users.
-
- Notes
- -----
-
- 1. REHASH writes to the CONS: device, so it can be run remotely from
- RBBS on an "exit to DOS" jump.
-
- 2. If RBBS reports insufficient space in a given users file, try
- raising the /EU or /MF values.
-
- 3. The '/' parameters can be in any order, but the messages and users
- file names have to be the first two parameters.
-
- Source Code
- -----------
-
- The source code, written in MicroSoft QuickBASIC, is included.
-
- Errors
- ------
-
- REHASH first reads the specified users file, and figures out the
- number of records it thinks will be required to resize your file. It
- then tries resizing with that number. If it can't fit all of the
- users into that size users file, it tries the next higher size. So,
- if you see that it "fails" at resizing, don't worry. It'll just go on
- and try again (up to a limit, of course).

-
- Guarantees
- ----------
-
- If you always back up your RBBS system files before using REHASH,
- you'll never lose data...
-
-
- Good luck!
