AV.DOC 1 Revised: 05/28/96
The AV.EXE program shows a directory of one or more archive files (ZIP, ZOO,
etc), including some self-extracting files. Features of this program:
* The directory information is presented in full-screen mode and you can
use PgUp and PgDn to scroll about the screens.
* Allows you to sort the display of the members in a number of ways.
* Allows you to reset the file date of the archive to match the date of
the most recent member of the archive.
* Provides the ability to filter out what members are displayed.
* Scroll through up to 500 archives.
A typical display might look (in part) like the following:

When viewing a screen's worth of information, you can typically choose among a
number of options including the following:
PgUp view the previous screen's worth
PgDn view the next screen's worth
Home top line
End bottom line
Up move the screen up one line
Down move the screen down one line
Sort change the sort order for this and subsequent files;
you're prompted for "BY?" and you should enter either
"-x" or "x" or press Esc to get out of this: the archive
is reread after you ask to re-sort it; x is one of:
N = file name
E = file extension
S = file size of the original (non-compressed) file
C = current (compressed) size of the file
D = file date and time
R = compression ratio
P = path and file name order
O = original order (no sorting)
the "-" says to reverse the sort order (e.g. biggest files
first instead of last)
Filter prompts you for a string; only member names that match that
string are allowed through (does not accept wildcards; just say
something like "COM" if you want all COM files)
Ctrl-PgDn go to the next archive file (if any)
Ctrl-PgUp go to the previous archive file (if any)
Quit return to DOS (Ctrl-C also works) (with confirmation)
Date update the archive date
Del delete the archive (with confirmation)
F1 help information
These options are presented on the right side of the screen and can be selected
with the mouse cursor if one is available.
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 AV=whatever), or
- From the command line (see "Syntax" below)
AV.DOC 3 Revised: 05/28/96
Syntax:
AV filespec [ /-P | /P ] [ /Ox | /O-x ] [ /DATE ] [ /Iinitfile | /-I ]
[ /MOUSE | /-MOUSE ] [ /Q ] [ /? ] [ > filename ]
where:
"filespec" is the file specification to process. Can include drive, path, and
wildcards if desired.
"/P" says to view the directory in page mode. This is typically the default.
The default is automatically /-P (which can't be overridden) if redirection ("AV
... > filename") is used.
"/-P" says to view the directory not in page mode. This prevents you from being
offered the fix-date option as well. This mode is automatic if redirection ("AV
... > filename") is used.
"/Ox" and "/O-x" allow you to specify the display order for the files. "x" can
be one of the following:
N = file name
E = file extension
D = file date and time
S = file size of the original (non-compressed) file
C = current (compressed) size of the file
R = compression ratio
P = path and file name order
O = original order (no sorting)
If you precede the "x" with a dash ("-"), the sort will be done in reverse
order. Initially defaults to /OO.
"/DATE" resets the file date to that of the most recent member. Automatically
invokes /-P. The command "AV *.* /DATE /Q" is a quick way to reset the file
date stamps for all archives in your current subdirectory.
"/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 "/IAV.INI".
"/-I" (or "/INULL") says to skip loading the initialization file.
AV.DOC 4 Revised: 05/28/96
"/MOUSE" says to activate the mouse if present. This is initially the default.
"/-MOUSE" says to skip activating the mouse even if present.
"/Q" skips the display of the member names. Automatically invokes /DATE and /-P
and is typically used in cases where you want to reset all file dates (e.g. "AV
*.* /Q").
"/?" or "/HELP" or "HELP" shows you the syntax for the command.
">filename" redirects the output to a text file. This automatically invokes the
/-P option. This is useful for getting a complete listing of the contents of
your compressed files. For example:
AV *.* > TEMP.TXT
Return codes:
AV returns the following ERRORLEVEL codes:
0 = no problems
254 = no valid archives were found
255 = syntax problems, file not found, or /? requested
