UNSIT v1.5a by Allen G. Weber
Ported to the ST by Alan Hamilton 12/17/90
This program will extract files stored using the Macintosh program
Stuffit. This release fixes a bug that prevented the extraction of
RLE compressed files. Running it via Install Application now works.
The v option now gives an ARC style verbose file listing, rather than
the brief UNIX listing. The l option still gives the UNIX style
listing.
Files included:
UNSIT.TTP The UNSIT program
COMPRESS.TTP Program used by UNSIT to decompress LZW
UNSIT.DOC UNIX documentation for UNSIT
READ.ME The file you are reading now
UNSIT.TTP and COMPRESS.TTP must be kept in the same folder. If you use
ARCSHELL, it must be in the same folder as UNSIT.TTP and COMPRESS.TTP.
In addition to the UNIX style commands listed in UNSIT.DOC, limited command
compatibility with ARC is also supported:
unsit {exlv}[h] SITfile [destination]
x or e Extract files (data fork only)
l List files (UNIX style)
v Verbose file listing (ARC style)
h Hold screen -- wait for a keypress before returning to the Desktop
All files will be extracted to the destination path. If you specify a
destination path, you have to specify one of the command flags too.
x foo.sit c:\ will work
foo.sit c:\ will NOT work
If you only specify a SIT file, with no command flags or destination path,
both the data and resource forks will be extracted to the current default
folder.
UNSIT creates a temporary file called UNSIT.TMZ. Don't use this as the
name for any of your files.
UNSIT can be used in one of three ways:
1. TOS-Takes-Parameters. Double click on UNSIT's icon, and enter the
parameters in the dialog. They can be either upper case or lower case.
2. Install Application. Single click on UNSIT's icon, and select Install
Application in the Desktop's Options menu. Fill in the application type
with SIT, and click on install. Select Save Desktop to make the installation
permanent. After UNSIT is installed, you can uncompress a SIT file by
double clicking on it. This does not work well under versions of TOS prior
to 1.4.
3. Charles F. Johnson's ARCSHELL. Follow ARCSHELL's instructions for
installing an alternate ARC utility. Only the Extract, List, and
Verbose list options are supported. The only extract option that is
valid is "All". "To Folder" and "w/ Query" will NOT work. You can make the
Item Selector come up with a default file type of SIT, rather than ARC, by
changing the directory line from *.ARC to *.SIT. Next, Select a SIT file
and do some operation (list files is a good harmless one). Finally, save
ARCSHELL's configuration. From then on, ARCSHELL will remember to use
*.SIT as the file type. If you change the default ARC or DATA drives
on the main ARCSHELL dialog, ARSHELL will go back to using .ARC.
MACINTOSH FILE INFO
===================
Macintosh files are made up of two parts: a data fork, and a resource fork.
The resource fork is vaguely akin to the ST's .RSC files. UNSIT will extract
the resource fork if you really want it, but under GEM it will do you no
good. What you want is the data fork, which contains the sound data,
text, graphics images, or whatever. UNSIT also creates a .INF file which
contains information such as the creation date, Macintosh Finder and
System flags, etc.
Most ST sound players can play Macintosh sound samples. You will have to
convert it to a .SND file (with the speed data prepended).
MacPaint documents can be viewed with PicSwitch.
Macintosh text files only have a cursor return at the end of each line.
You will have to use a utility (such as DCOPY) to add linefeeds, otherwise
all the text will print on one line.
