- MTOOLS
- version 1.6.2 - 5 Jul 89
-
- This is a collection of MSDOS tools to allow you to read and write to
- MSDOS formatted diskettes from a Unix based system.
-
- The following MSDOS commands are emulated:
-
- Mtool MSDOS
- name equivalent Description
- ----- ---- -----------
- mcopy COPY copy MSDOS files to/from Unix
- mdel DEL/ERASE delete a MSDOS file
- mdir DIR display a MSDOS directory
- mkdfs FORMAT Format and build s DOS file system.
- mmd MD/MKDIR make a MSDOS sub directory
- mrd RD/RMDIR remove a MSDOS sub directory
- mread COPY low level read (copy) a MSDOS file to Unix
- mren REN/RENAME rename an existing MSDOS file
- mtype TYPE display contents of a MSDOS file
- mwrite COPY low level write (copy) a Unix file to MSDOS
- * CD change working directory
-
- * by use of the environmental variable MCWD
-
- The formats of IBM PC floppy disk drives are:
-
- bytes per sectors per tracks number total disk introduced
- sector track per side of sides capacity size in MSDOS

- Find UNIX device(s) capable of reading one or more of these formats
- and edit "devices.c" to add them to the driver switch, you may
- add the same device more than once if it supports multiple formats
- and needs "ioctls" to be set to the right physical parameters.
-
- The disk geometry can be kept in the environment for unusual cases,
- init.c will pass "NCYL", "NSECT" and "NTRACK" to the disk parameter
- setting routine (if any). This should be documented in an "mtools"
- manual page giving an overview of the whole package, this file is a
- start.
-
- The manuals are very terse... it's assumed that the reader is already
- familiar with MSDOS.
-
- The use of the environmental variable MCWD to keep track of the current
- working directory is a little awkward, especially since there is no
- 'change directory' command. Bourne shell users will have to type two
- commands to initially set their working directory, ie:
-
- MCWD=/TMP
- export MCWD
-
- Wildcards are only applied to filenames and not to directory names. For
- example '/usr/local/*.c' is appropriate, but '/usr/l*/main.c' is not.
-
- I really wanted to avoid the use of a 'text' mode and a 'data' mode when
- transferring files, but I couldn't find a better way. It gets rather
- confusing and it's quite possible to mess up a file if you apply the
- text mode when it is not appropriate (ie: to a COM or EXE file).
- Likewise, if you forget to apply the text mode (to a Unix text file)
- then if the file is used under MSDOS, it will be missing carriage
- returns. However, if you aren't going to use the files on your Unix
- system (you just intend to hold the files and then transfer them back to
- MSDOS later) then you shouldn't use the text mode during either mread or
- mwrite. This is because, the text mode is only useful if the files are
- gonna be used under Unix.
-
- The implementation of the Mcopy command is somewhat clumbsy since the
- MSDOS drive designation "A:" is used. Mcopy is really a front-end to
- the low level Mread and Mwrite commands.
-
- There are is a shell archives called "Unixpc.shar" that contain files
- specific to the AT&T Unix PC 7300/3b1.
