1 Introduction
==============
hfsutils is a collection of tools for accessing Macintosh
HFS-formatted volumes. HFS is the Hierarchical File System used on
modern Macintosh computers.
The utilities were originally part of the hfsutils package for UNIX
systems. This port uses the emx programming environment. There are
binary versions for OS/2 and Windows 95/NT. Both versions also run
under DOS.
hfsutils is free software, distributed under the GNU General Public
License. Please see the file `COPYING' for details.
2 Installing hfsutils
=====================
2.1 System requirements
-----------------------
hfsutils requires a 386 processor or better. Supported operating
systems are DOS version 3 and higher, OS/2 2.0 and higher, and Win32
(Windows 95/NT).
2.2 Additional software
-----------------------
In order to use hfsutils under Windows 95/NT in native mode, you need
the RSXNT extender. This package is available as
ftp://ftp.uni-bielefeld.de/pub/systems/msdos/misc/rsxnt131.zip
For OS/2, you need the emx runtime environment, available as
ftp://ftp.leo.org/pub/comp/os/os2/leo/devtools/gnu/emx+gcc/emxrt.zip
Only the OS/2 parts of the runtime need to be installed, as hfsutils
uses rsx under DOS.
2.3 Installation instructions
-----------------------------
These are the steps for installing hfsutils.
1. Set the HOME environment variable to point to a directory where
hfsutils can store the file `hfs.cfg'. This can be done by adding
a line like
SET HOME=C:\HFSUTILS
to the AUTOEXEC.BAT file (DOS and Windows95) or the CONFIG.SYS
file (OS/2). Under Windows NT, environment variables are set in
the `System' settings of the Control Panel. Note that the
directory has to be writable.
2. Add the directory where you put hfsutils to your PATH. If you
want to avoid this, you can set the HFSUTILS variable to point to
this directory instead.
3 Using the utilities
=====================
In this section, the term `DOS' refers to the PC environment (as
opposed to the Macintosh environment). This includes plain DOS, OS/2
and Windows 95/NT.
3.1 hmount - introduce a new HFS volume and make it current
-----------------------------------------------------------
hmount <source-path> [<partition-no>]
hmount is used to introduce a new HFS volume. A DOS pathname to the
volume's source must be specified. The source may be a drive letter
or a regular file containing an HFS volume image.
If the source medium is partitioned, one partition must be selected to
be mounted. If there is only one HFS partition on the medium, it will
be selected by default. Otherwise, the desired partition number must
be specified (as the ordinal nth partition) on the command-line.
Partition number 0 can be specified to refer to the entire medium,
ignoring what might otherwise be perceived as a partition map,
although in practice this is probably only useful if you want this
command to fail when the medium is partitioned.
The mounted volume becomes "current" so subsequent commands will refer
to it. The current working directory for the volume is set to the
root of the volume. This information is kept in a file named
`hfs.cfg' in the home directory.
If the source medium is changed (e.g. floppy or CD-ROM disc
exchanged) after hmount has been called, subsequent HFS commands will
fail until the original medium is replaced or a different volume is
made current. To use the same source path with the different medium,
reissue the hmount command.
Examples:
hmount A:
If a Macintosh floppy disk is available as A:, this command makes the
floppy current for other HFS commands such as hls, hcd, hcopy, etc.
hmount macdisk.bin
Mounts a volume that resides in the file `macdisk.bin'.
3.2 humount - remove an HFS volume from the list of known volumes
-----------------------------------------------------------------
hmount [<volume-name-or-path>]
humount is used to forget about an HFS volume previously mounted with
hmount. Either the volume's name or the path to the volume may be
used to specify the volume. If no name or path is given, the current
volume is assumed.
It is not strictly necessary to use this command. It does not affect
any physical volumes; it only updates the file named `hfs.cfg' in the
home directory used to keep track of the currently known HFS volumes.
3.3 hvol - display or change the current HFS volume
---------------------------------------------------
hvol [<volume-or-path>]
With no arguments, hvol displays the name and path to the "current"
HFS volume as well as the names and paths of all previously mounted
("known") volumes.
With an argument, hvol changes the current volume to be the one
specified. Either the name of the volume or the path to its source
can be specified. The volume must have been previously mounted using
hmount.
A separate "current working directory" is maintained for each mounted
volume. This information is kept in a file named `hfs.cfg' in the
home directory.
3.4 hls - list files in an HFS directory
----------------------------------------
hls [<options>] [<hfs-path> ...]
hls lists files and directories contained in an HFS volume. If one or
more arguments are given, each specified file or directory is shown;
otherwise, the contents of the current working directory are shown.
Options:
-1 Output is formatted such that each entry appears on a single
line. This is the default when the standard output is
redirected to a file or pipe.
-a All files and directories are shown, including "invisible"
files, as would be perceived by the Macintosh Finder.
Normally invisible files are omitted from directory listings.
-b Special characters are displayed in an escaped backslash
notation. Normally special or non-printable characters in
filenames are replaced by a question mark (?).
-c Sort and display entries by their creation date, rather than
their modification date.
-d List directory entries themselves rather than their contents.
Normally the contents are shown for named directories on the
command-line.
-f Do not sort directory contents; list them in the order they
appear in the directory. This option effectively enables -a
and -U and disables -l, -s, and -t.
-i Show the catalog IDs for each entry. Every file and directory
on an HFS volume has a unique catalog ID.
-l Display entries in long format. This format shows the entry
type ("d" for directory or "f" for file), flags ("i" for
invisible), file type and creator (four-character strings for
files only), size (number of directory sub-contents or file
resource and data bytes, respectively), date of last
modification (or creation, with -c flag), and pathname.
Macintosh "locked" files are indicated by "F" in place of "f".
-m Display entries in a continuous format separated by commas.
-q Replace special and non-printable characters in displayed
filenames with question marks (?). This is the default when
the standard output is connected to a terminal (as opposed to
a file or pipe).
-r Sort entries in reverse order before displaying.
-s Show the file size for each entry in 1K block units. The size
includes blocks used for both data and resource forks.
-t Sort and display entries by time. Normally files will be
sorted by name. This option uses the last modification date
to sort unless -c is also specified.
-x Display entries in column format like -C, but sorted
horizontally into rows rather than columns.
-w <width>
Format output lines suitable for display in the given <width>.
Normally the width will be determined from your terminal, from
the environment variable COLUMNS, or from a default value of
80.
-C Display entries in column format with entries sorted
vertically. This is the default output format when standard
output is connected to a terminal.
-F Cause certain output filenames to be followed by a
single-character flag indicating the nature of the entry;
directories are followed by a colon (:) and executable
Macintosh applications are followed by an asterisk (*).
-N Cause all filenames to be output verbatim without any escaping
or question-mark substitution.
-Q Cause all filenames to be enclosed within double-quotes (")
and special/non-printable characters to be properly escaped.
-R For each directory that is encountered in a listing,
recursively descend into and display its contents.
-S Sort and display entries by size. For files, the combined
resource and data lengths are used to compute a file's size.
-U Do not sort directory contents; list them in the order they
appear in the directory. On HFS volumes, this is usually an
alphabetical case-insensitive ordering, although there are
some idiosyncrasies to the Macintosh implementation of
ordering. This option does not affect -a, -l, or -s.
3.5 hdir - display an HFS directory in long format
--------------------------------------------------
hdir [<options>] [<hfs-path> ...]
hdir is an alternative interface to hls. It is equivalent to
supplying hls the -l flag.
3.6 hcopy - copy files from or to an HFS volume
-----------------------------------------------
hcopy [-m | -b | -t | -r | -a] <source-path> [...] <target-path>
hcopy transfers files from an HFS volume to DOS or vice versa. The
named source files are copied to the named destination target, which
must be a directory if multiple files are to be copied.
Copies are performed using a translation mode, which must be one of:
-m MacBinary II: A popular format for binary file transfer. Both
forks of the Macintosh file are preserved. This is the
recommended mode for transferring arbitrary Macintosh files.
-b BinHex: An alternative format for ASCII file transfer. Both
forks of the Macintosh file are preserved.
-t Text: Performs end-of-line translation. Only the data fork of
the Macintosh file is copied.
-r Raw Data: Performs no translation. Only the data fork of the
Macintosh file is copied.
-a Automatic: A mode will be chosen automatically for each file
based on a set of predefined heuristics.
If no mode is specified, -a is assumed.
If a DOS source pathname is specified as a single dash (-), hcopy will
copy from standard input to the HFS destination. Likewise, a single
dash used as a DOS destination pathname will cause hcopy to copy the
HFS source to standard output.
Copied files may have their filenames altered during translation. For
example, an appropriate file extension may be added or removed, and
certain other characters may also be transliterated.
The destination target must not be ambiguous; that is, it must be
obvious whether the target is on the DOS filesystem or on an HFS
volume. As a rule, HFS targets must contain at least one colon (:),
usually as the beginning of a relative pathname or by itself to
represent the current working directory. As a special exception, if
the target pathname start with a drive letter, it will be assumed to
be on the DOS filesystem. To make a DOS target unambiguous, either
use an absolute pathname or precede a relative pathname with a dot and
slash (./).
3.7 hdel - delete both forks of an HFS file
-------------------------------------------
hdel <hfs-path> [...]
hdel deletes files from the current HFS volume. Both forks (resource
and data) of each named file are removed, freeing space for other
files.
3.8 hrename - rename or move an HFS file or directory
-----------------------------------------------------
hrename <hfs-src-path> [...] <hfs-target-path>
hrename changes the name and/or location of one or more files or
directories. If only one source path is specified and the target path
is in the same directory as the source, only the name is changed.
Otherwise the source object is moved as well as possibly being
renamed.
If multiple source paths are specified, the target must be a
directory, and all of the source objects will be moved into it
(keeping the same names.)
If the source path refers to the root directory of a volume, the
volume name will be changed. The root directory cannot be moved.
Note that volume names can only have 1-27 characters, while all other
names may have 1-31 characters.
3.9 hattrib - change HFS file or directory attributes
-----------------------------------------------------
hattrib [-t TYPE] [-c CREA] [-|+i] [-|+l] <hfs-path> [...]
hattrib permits the alteration of HFS file attributes. The
MacOS-defined type and creator attributes can be set using the -t and
-c flags, respectively. A file's invisible flag can be set or cleared
with +i and -i, respectively. Finally, a file's locked flag can be
set or cleared with +l and -l.
All files mentioned on the command line will receive the specified
attributes, regardless of the file's current attributes. Any
attribute not mentioned in the command line is left unchanged.
Note that the invisible and locked flags only have meaning to the
Macintosh Finder.
3.10 hcd - change working HFS directory
---------------------------------------
hcd [<hfs-path>]
hcd is used to change the notion of the "current working directory"
for the current HFS volume. All subsequent HFS commands will
interpret filenames relative to this directory, unless absolute
pathnames are used.
If the argument pathname is omitted, hcd will change to the root of
the current volume.
Note: Although absolute pathnames can be given to hcd, the full
pathname must match the current volume; it cannot specify a path for a
different volume. Use hvol or hmount to change the current volume.
(Each volume has its own independent current working directory.)
3.11 hpwd - print the full path of the current HFS working directory
--------------------------------------------------------------------
hpwd
hpwd displays the complete (absolute) HFS pathname to the current
working directory on the current volume. The current working
directory can be changed with the hcd command.
3.12 hmkdir - create a new HFS directory
----------------------------------------
hmkdir <hfs-path> [...]
hmkdir creates new, empty directories (folders) on the current HFS
volume. There must not already be a file or directory with each named
path.
3.13 hrmdir - remove an empty HFS directory
-------------------------------------------
hrmdir <hfs-path> [...]
hrmdir deletes directories (folders) from the current HFS volume.
Each named directory must already be empty.
3.14 hformat - create a new HFS filesystem and make it current
--------------------------------------------------------------
hformat [-l <label>] <destination-path> [<partition-no>]
hformat is used to write a new HFS filesystem to a volume. A DOS
pathname to the volume's destination must be specified. The
destination may be either a drive letter or a regular file, but must
already exist and be writable. (If a regular file, the size of the
file determines the maximum size of the resulting volume image.) Note
that the medium must already be low-level formatted. To format a new,
unformatted diskette with hformat, format it with the usual FORMAT
utility first.
An optional label can be specified to name the volume. The name must
be between 1-27 characters and cannot contain a colon (:). By
default, the volume will be named Untitled.
If a partition number n is specified, the nth HFS partition in the
existing medium will receive the filesystem. By default, and also
when n is 0, the entire medium will be formatted with the new
filesystem. If a partition is specified, it must already exist.
The new volume will be empty, but will also become "current" so
subsequent commands will refer to it. The current working directory
for the volume is set to the root of the volume.
4 Usage notes
=============
4.1 HFS pathnames
-----------------
HFS pathnames consist of colon-separated components. Unlike DOS
pathnames, an HFS path which begins with a colon is a relative path,
and one which does not is an absolute path. As sole exception to this
rule, a path not containing any colons is assumed to be relative.
Thus :Foo:Bar is a relative path, while Foo:Bar is an absolute path.
Absolute pathnames always begin with the name of the volume itself.
Any occurrence of two or more consecutive colons in a path causes
resolution of the path to ascend into parent directories.
4.2 Wildcard expansion
----------------------
The utilities allow using the wildcard characters `*' and `?' to
specify filenames. However, the meaning of these characters is
somewhat more complicated than in most DOS programs. The reason is
that wildcard expansion is performed twice, for local files and for
files on the HFS volume.
The first expansion is similar to that used in UNIX systems. Any
arguments that contain wildcards will be replaced with a list of the
matching filenames in the native file system. If no files match the
wildcard pattern, the wildcard argument is kept unchanged. Moreover,
wildcards within double quotes will not be expanded.
The second expansion is similar, but matches files on the HFS volume.
It starts with the results of the first wildcard expansion, and
applies only to arguments that specify HFS files. Therefore, any
wildcards for HFS file specifications must be protected from being
expanded in the first step by double quotes.
In the expansion of HFS filenames, the backslash character may be used
to quote a single character. This makes it possible to specify HFS
filenames that contain special characters such as `*' and `?'.
Some common examples follow.
- To list all filenames on the current HFS volume that begin with
`foo':
hls "foo*"
Note that the double quotes are necessary to prevent the `*' to be
expanded against the DOS files.
- To copy all DOS files whose names end in `.c' to the HFS volume:
hcopy *.c :
Here the wildcard is expanded to a list of matching files in the
current directory.
- To delete all files in the current directory on the HFS volume:
hdel "*"
Alternatively, you can use:
hdel :*
This works because the specification begins with a colon and hence
does not match any DOS files. Hence it is not expanded in the first
expansion.
- To copy `myfile.txt' to the HFS file `My*File':
hcopy myfile.txt ":My*File"
The asterisk needs to be protected from the expansion against DOS
files. Since hcopy does not perform any expansion for target files,
the asterisk should not be escaped by a backslash.
- To copy the HFS file `My*File' to the file `myfile' in DOS:
hcopy ":My\*File" myfile
The backslash ensures that the asterisk is not expanded in the
second expansion. The `:' is not strictly necessary.
4.3 Environment variables
-------------------------
The utilities use the following environment variables:
HFSUTILS
Specifies the directory where the executable `hfsutil.exe' and
the extender `rsxhfs.exe' reside. These files are first
looked for in the current directory, then in the directories
listed in the PATH variable, and finally in the directories
specified in the HFSUTILS variable.
HOME Specifies the "home directory" where the file `hfs.cfg' will
be placed. This file records the volumes known to hfsutils.
If this variable is not set, the current directory will be
used. Since this causes problems when the current directory
is changed, it is recommended that this variable be used.
4.4 Notes for DOS users
-----------------------
Supported devices
-----------------
Under DOS, the utilities work with block devices such as floppy disks.
The device must be known to DOS and have a drive letter. CD-ROMs can
not be accessed, because they are not viewed as block devices in DOS.
DPMI
----
hfsutils requires a DPMI server. A server is included (the program
`CSXHFS.EXE'). It will be loaded automatically if no other server is
present, and must be located either in the current directory or in a
directory listed in the HFSUTILS variable.
4.5 Notes for Windows95 users
-----------------------------
When running as a native Win32 application, hfsutils can only access
disk drives directly under Windows NT. For Windows95, you have to use
the RSX extender and run hfsutils as a DOS application. This is done
by running RSXHFS to load the utilities, as in the following example:
rsxhfs hcopy foo :macfoo
Note that this limits the devices to those that are accessible under
plain DOS, i.e., diskettes. CD-ROMs and other devices work only in
native Win32 mode under Windows NT.
4.6 Using Macintosh diskettes
-----------------------------
The PC hardware cannot handle 800k Macintosh diskettes. Therefore,
hfsutils can only access 1.44M HFS-formatted Macintosh diskettes.
Note that 400k and 800k Macintosh diskettes usually use an older file
system, MFS, which is not supported by this software either.
4.7 Known problems
------------------
- Some hybrid CD-ROMs have incorrect volume size information, and
therefore the HFS part cannot be accessed with the normal method.
This problem has been circumvented under OS/2, but still remains in
the Win32 version.
- There is currently no way to access devices such as SCSI hard disks,
which are not assigned a drive letter.
5 History of changes
====================
5.1 Changes in version 3.1a
---------------------------
- Upgraded to hfsutils 3.1. The most important changes in this
version are:
- A new block cache that greatly increases performance.
- hmount and other commands now properly handle relative pathnames,
even if the current directory changes.
- Several bug fixes.
- OS/2 version: Fixed a problem with some hybrid CD-ROMs where the HFS
part could not be accessed. (The problem still remains in the Win32
version.)
