UN - Unpack util v2.1!
(c) by Dan Silfvast 1993-1995
USERS MANUAL
INTRODUCTION!
-------------
UN is a small util which I created for use in "everyday extracting"
It detects the type of the archive and automatically uses the correct
extractor. UN still detects only ZIP,ARJ and LHA archives, but I'm working on
support for most known formats. It also detects some of the self extracting
versions of these archives.
UN itself does not extract files, so if you'll still need the correct
extractor. In other words, UN can't handle ZIP files if PKUNZIP is not found.
I created this util because I have many archives in different formats, and
when I want to extract I usually don't remeber the complete filename.
Ofcourse I could use DIR to find out the filename, but it's 'too slow'
for me. And I also usually extract SFX archives manually.
For more history read the UPDATE.DOC file.
USAGE: (command line)
------
UN [-option] file [destination] [parameters]
OPTION= Option for UN.
The following options are avilable:
-E = Extract without pathname
-X = Extract with pathname (default)
-L = List contents of archive
-D = Delete files from archive.
-A = Add files to existing archive.
-? = Shows command line help.
FILE = The archive to be exctracted.
You CAN use asterisks like * and ? in the filename, but if don't
UN will automatically search the directory for files matching
the written string.
Some examples of filenames:
FILE1.ARJ = Direct extraction of file. Just like using normal ARJ x
FILE*.ARJ = UN searches the directory for files beginning with
'FILE' with the extension 'ARJ'. If only one file is found
it will be extracted, otherwise UN enters file selection
mode. (explained later)
FILE = UN searches the directory for files beginning with 'FILE'
Then it will continue like with 'FILE*.ARJ'
*.ARJ = UN shows a list over all files with the extension ARJ.
C:\ARCHIVES\ = UN shows all files in the directory and let's you
select one for extracting.
(other parameters)
DESTINATION = Destination for extracted files.
This is sent directly to the exctractor.
Ex. C:\TEMP
PARAMETERS = Parameters for the extractor. Like -va (for ARJ) etc...
ARJ and LHA extracts the directory structure by default,
but for ZIP and PAK files this parameter must be added from
the command line.
FILE SELECTION:
---------------
The file selection system is activated if UN finds more than one file
matching the filename gived at the command line.
Keys while in file selection system:
ARROW KEYS: Move around cursor.
PGUP : Moves one page up.
PGDOWN : Moves one page down.
HOME : Moves to the beginning of the list.
END : Moves to the end of the list.
L : Shows contents of current file. (Explained later)
H : Shows Help screen.
S : Changes file sort order.
Files can be sorted by: Name, Extension, Size or Date
The default sort order is Unsorted
T : Toggles file info in list
In other words, shows file size & date on same line as name
SPACE : Tags files for extracting / viewing (with -L parameter)
ENTER : Proceed with current file or tagged ones.
ESC : Quits UN.
ARCHIVE LIST MENU:
------------------
Pressing L in the File Selection Menu activates the Archive List menu.
If the current file is an archive a list of the files in the archive is
shown. The archive list menu uses the same keys as the file selection menu,
except for the sort funktion, which I haven't yet implanted in the list
section. The colors don't work either.
You can tag files in the archive for extraction with SPACE.
COMING UP NEXT!
---------------
- Some kind of INI file system.
- Support for more archive formats.
- Support for moving in directories
- Copy, Move, Delete commands
BTW. If you have any good ideas then please write to the author. (Me :))
