- FILUPDAT.DOC 1 Revised: 10-28-96
-
- Introduction:
-
- This program is designed to make updating of files and source code both easier
- and quicker. It compares a list of files in a source directory to a list of
- files in a destination directory and copies any files that are newer than the
- ones found in the destination directory. This is quicker than copying all of
- the files with DOS wildcard commands and cleaner than copying everything when
- you only want some of the files in the destination area.
-
-
- The control card file:
-
- FILUPDAT requires an ASCII control card file to be created. The control card
- file can consist of five types of records:
-
- (1) comments: These records start with semi-colons or colons or are blank.
- They are available primarily for documenting what you're doing.
-
- (2) source directory: These records start with "-S" (or "-F" for "from")
- followed by the path to copy the files from. Something like "-SC:\QB45"
- works fine.
-
- (3) destination directory: These records start with "-D" (or "-T" for "to")
- followed by the path to copy the files to. For example,
- "-DJ:\EBBNEW\DOCS".
-
- (4) exclusion specification: These records start with "-X" followed by a space
- and one or more filespecs (typically with wildcards). For example, your
- main file specification may be "*.*" but you can exclude any QuickBASIC
- source code files or object modules by including a "-X *.BAS *.OBJ"
- statement.
-
- (5) files: These records have a single file name (e.g. "EBBFFILE.WP") that is
- to be copied from the source directory to the destination directory. File
- specifications can include standard DOS wildcards ("*" and "?"). A comment
- can follow the file name provided the comment starts with a colon or a
- semi-colon.
-

-
- Source and destination cards can be changed throughout the control card file.
- Files are copied based on the most recent source/destination card before the
- file card. Changing either the source or destination will reset the exclusion
- specification so you have to respecify the -X card if desired.
-
- Also note that cards are processed sequentially. The exclusion specification
- card only affects file name card(s) which occur after it.
-
-
- A sample control card file might look like this:
-
- ; Sample file
- -SC:\PDOX
- -DJ:\EBBNEW\PRGS
- CUSTOM.SC
- ADDRESS.SC
- ZIPCODE.SC
- ; Specifying another source file path; destination still the same
- -SC:\MINE
- NEWUSER.SC
-
-
- Specifying parameters:
-
- Parameters for this program can be set in the following ways. The last setting
- encountered always wins:
- - Read from an *.INI file (see BRUCEINI.DOC file),
- - Through the use of an environmental variable (SET FILUPDAT=whatever), or
- - From the command line (see "Syntax" below)

-
- Syntax:
-
- FILUPDAT { ctlfile | /Cctlfile } [ /-A ] [ /-R ] [ /CLONE ]
- [ /Flist_file [ /OVERWRITE | /APPEND | /-OVERWRITE | /OVERASK ] ]
- [ /FULL ] [ /ABORT | /SKIP | /CREATE ]
- [ /MONO ] [ /Q ] [ /Iinitfile | /-I ] [ /? ]
-
- where:
-
- "ctlfile" or "/Cctlfile" is the name of the control statement file. It can
- include path information if necessary.
-
- "/Flist_file" says you want a text file created which tells you what files were
- considered and what happened to each of them. The "list_file" is the name of
- the file. This is primarily used for checking the operation of the utility. The
- file name can include path information if necessary; it must contain a period
- (use something like "/FTEST." if no extension is used).
-
- "/OVERWRITE" says that if the list_file already exists, don't prompt before
- overwriting it.
-
- "/APPEND" says to append to the list_file if it already exists.
-
- "/-OVERWRITE" says to abort if the output file exists already.
-
- "/OVERASK" says to prompt if the output file exists already. This is the
- default.
-
- "/FULL" says to write out full comparison information in the list_file. This is
- primarily for debugging purposes but it includes the numeric representation of
- the date and time for both the source and destination files.
-
- "/ALL" says to copy all files in your ctlfile regardless of relative ages.
-
- "/ABORT" says that if any source or destination subdirectory is missing, give an
- error message and abort the program. This is initially the default.
-
- "/SKIP" says that if any source or destination subdirectory is missing, give an
- error message, skip all files for that specification, but otherwise continue
- running the program.
-
- "/CREATE" says that if a destination subdirectory is missing, give an error
- message and try to create the subdirectory. If successful, copy the desired
- files to it. If not successful, skip all files for that specification but
- otherwise continue running the program. If the source subdirectory is not
- found, the program will operate as if /SKIP was specified.
-
- "/MONO" (or "/-COLOR") does not try to override screen colors. Initially
- defaults to "/COLOR".
-
- "/COLOR" (or "/-MONO") allows screen colors to be overridden. This is initially
- the default.
-
- "/Q" turns off the file-by-file status reporting.
-
-
- FILUPDAT.DOC 4 Revised: 10-28-96
-
- "/Iinitfile" says to read an initialization file with the file name "initfile".
- The file specification *must* contain a period. Initfiles are described in the
- BRUCEINI.DOC file. Initially defaults to "/IFILUPDAT.INI".
-
- "/-I" (or "/INULL") says to skip loading the initialization file.
-
- "/?" or "/HELP" or "HELP" shows you the syntax for the command.
-
-
- Return codes:
-
- FILUPDAT returns the following ERRORLEVEL codes:
-
- 0 = no problems
- 250 = operation aborted by pressing Escape
- 251 = invalid control file or bad drive/subdirectory specification
- 252 = copy failed
- 253 = no files found to copy
- 255 = syntax problems, or /? requested
