Listing Archive Contents
Let's start by getting a list of the files from a disk image.
cp2 catalog prodos/extended.do
File: prodos/extended.do Disk image (Unadorned, order=dos/sect) - 140KB ProDOS "Forked", 47 blocks free Type Auxtyp Modified Length Storage *Name ---- ------ --------------- -------- -------- ---------------------------------- FON+ $0001 22-Feb-92 19:46 112602 114176 Helvetica TEXT+ ttxt 24-Jun-22 11:15 286 1536 ExtText
The output begins with a summary of the disk image characteristics, namely that it's a 140KB image (presumably from a 5.25" floppy disk), and has a ProDOS filesystem with the volume name "Forked". This is followed by columns with the file type information, modification date, file size, and the filename.
The file "Helvetica" is a font file with a resource fork, so
it has the ProDOS file type FON, and the type is followed by a '+'
to indicate that it's an extended file. The file "ExtText" is
a text file from a Macintosh, and has HFS file types rather than ProDOS types.
It also has a resource fork.
If you want to see more detail, you can add the --wide option:
cp2 v --wide prodos/extended.do
File: prodos/extended.do Disk image (Unadorned, order=dos/sect) - 140KB ProDOS "Forked", 47 blocks free Typ Aux HTyp Crea Access Created Modified D-Length D-Size R-Length R-Size Name --- ---- ---- ---- ------ --------------- --------------- -------- -------- -------- -------- ---- FON 0001 øøøø øøøø dnbwr 22-Feb-92 19:45 22-Feb-92 19:46 0 512 112602 113152 Helvetica TXT 0000 TEXT ttxt dnbwr 24-Jun-22 11:03 24-Jun-22 11:15 226 512 60 512 ExtText
Note that the command used was "v", rather than "catalog". Many commands have a "long name" and a "short name", which can be used interchangeably.
(The actual output for the HTyp and Crea fields uses Unicode "control pictures", so 0x00 is output as ␀ in the actual output. My web browser displays the control pictures as wider than normal characters, so I replaced those with ø above.)
The output for a file archive is slightly different.
cp2 v nufx/GSHK11.SEA
File: nufx/GSHK11.SEA Type Auxtyp Modified Format Length Size Name ---- ------ --------------- ------- -------- ---- ------------------------------ S16+ $DB07 10-Oct-92 15:11 LZW/2 130506 67% GSHK TXT+ $0000 10-Oct-92 15:04 LZW/2 29495 49% gshk.docs TXT $0000 10-Oct-92 14:13 LZW/2 5392 57% Release.Notes
There's a new column that shows the compression format, and a size field that shows the compressed size as a percentage of the original. You can use the --wide option here to get greater detail.
