10: ddooss [-]ddFFllrrttxx[_f_l_a_g_s] [_d_e_v_i_c_e] [_f_i_l_e ...]
11:
12: The command ddooss allows the COHERENT user to manipulate an MS-DOS
13: file system, which may be either a hard-disk partition or a
14: floppy disk. It can build an empty MS-DOS file system, label it,
15: list the files in it, transfer files between it and COHERENT, or
16: delete files from it.
17:
18: The given _d_e_v_i_c_e must be a special file that specifies an MS-DOS
19: file system, such as floppy-disk drive /ddeevv/ffhhaa00 or hard-disk
20: partition /ddeevv/aatt00aa. The default _d_e_v_i_c_e is /ddeevv/ddooss, which the
21: system administrator should link to the most commonly used device
22: name.
23:
24: ddooss converts between the differing file-name conventions of
25: COHERENT and MS-DOS. An MS-DOS _f_i_l_e argument may be specified in
26: lower or upper case, using `/' as the path-name separator. When
27: transferring files from MS-DOS to COHERENT, ddooss converts an MS-
28: DOS file name to a COHERENT file name in lower case only. If the
29: MS-DOS file name contains no extension, the COHERENT file name
30: contains no `.'. When transferring files from COHERENT to MS-
31: DOS, ddooss converts all alphabetic characters in a COHERENT file
32: name to upper case; if a period `.' appears at the beginning or
33: end of a file name, ddooss converts it to `_'. ddooss truncates the
34: part of the file name before the last `.' to a maximum of eight
35: characters and truncates the extension to a maximum of three
36: characters.
37:
38: The command line must specify exactly one of the following
39: _f_u_n_c_t_i_o_n_s.
40:
41: dd Delete each _f_i_l_e from the MS-DOS file system. This option
42: also allows the user to delete empty directories.
43:
44: FF Create an empty MS-DOS file system on a formatted diskette.
45: This option is analogous to the COHERENT command /eettcc/mmkkffss.
46: The COHERENT commands /eettcc/ffddffoorrmmaatt and /eettcc/mmkkffss initialize
47: a COHERENT diskette in two steps. The MS-DOS command ffoorrmmaatt
48: initializes an MS-DOS diskette by performing both the
49: physical and logical formatting operations with one command.
50: To initialize an MS-DOS diskette under COHERENT, use the
51: command /eettcc/ffddffoorrmmaatt -vv _d_e_v_i_c_e_n_a_m_e, followed by the command
52: ddooss FF _d_e_v_i_c_e_n_a_m_e. If _f_i_l_e is named, ddooss copies it to the
53: boot block of the file system. The ddooss command cannot build
54: a file system on a hard-disk partition.
55:
56: ll Label the MS-DOS file system. The command line must specify
57: exactly one _f_i_l_e argument, which gives the label.
58:
59: rr Replace each _f_i_l_e on the MS-DOS file system with the
60: COHERENT file of the same name. If a given _f_i_l_e argument
61: specifies a COHERENT directory, ddooss replaces its

73: subdirectories recursively to the MS-DOS file system unless
74: the ss flag is used. If no _f_i_l_e is specified, ddooss copies all
75: files in the current directory to the MS-DOS file system.
76:
77: tt List the files on the MS-DOS file system. If no _f_i_l_e
78: argument is given, ddooss lists the entire MS-DOS file system;
79: otherwise, it lists each _f_i_l_e. If a _f_i_l_e argument specifies
80: an MS-DOS subdirectory, ddooss lists its contents. ddooss lists
81: directories first in alphabetical order, then ordinary files
82: in alphabetical order.
83:
84: xx Extract each _f_i_l_e from the MS-DOS file system to a COHERENT
85: file of the same name. If a given _f_i_l_e argument specifies
86: an MS-DOS subdirectory, ddooss extracts its contents
87: recursively unless the ss flag is used. If no _f_i_l_e is given,
88: ddooss extracts all files from the MS-DOS file system to the
89: current COHERENT directory.
90:
91: The following _f_l_a_g_s are available.
92:
93: aa Perform ASCII newline conversion on file transfer. When
94: moving files from COHERENT to MS-DOS, this option converts
95: each COHERENT newline character `\n' (ASCII LLFF) to an MS-DOS
96: end-of-line (ASCII CCRR and LLFF); when moving files from MS-DOS
97: to COHERENT, it does the opposite. By default, ddooss performs
98: binary file transfer, without newline conversion.
99:
100: kk Keep the file modification time (mtime) on extract and
101: replace operations. By default, ddooss gives extracted or
102: replaced files the current time. With this option, ddooss
103: gives the extracted or replaced file the same time as the
104: original file.
105:
106: nn List files in order of creation (newest file last) rather
107: than in alphabetical order. This option applies only to the
108: table-of-contents function. ddooss always lists directories
109: before files, with or without the nn option.
110:
111: pp Perform a piped extract or replace (for use in pipelines).
112: The command line must specify exactly one _f_i_l_e argument.
113: For extract, ddooss reads the given _f_i_l_e and writes it to the
114: standard output. For replace, ddooss reads the standard input
115: and writes it to the given _f_i_l_e.
116:
117: ss Suppress extraction or replacement of subdirectories. By
118: default, ddooss extracts or replaces subdirectories
119: recursively.
120:
121: vv Verbose option. Provide additional information about each
122: function performed.
123:
124: [11-99]
125: A digit specifies a logical drive number on an extended MS-
126: DOS partition. For example, ddooss ttvv22 /ddeevv/aatt00cc lists the
127: directory of the second logical drive on extended MS-DOS

143: The first example copies all files located in directories ssoouurrcceess
144: and iinncclluuddee, as well as any subdirectories, from floppy drive
145: /ddeevv/ffvvaa11 to correspondingly named subdirectories in the current
146: COHERENT directory:

152: Note that ffvvaa11 is a high-density, 3.5-inch floppy disk in floppy-
153: disk drive 1 (a.k.a., drive B:). The files will be copied with
154: ASCII newline conversion and will retain the time and date that
155: they had under MS-DOS.
156:
157: The next example copies a file from an MS-DOS partition on your
158: hard disk. Suppose that CC: is the primary MS-DOS partition on
159: your first hard drive. The following command copies file
160: CC:\AAUUTTOOEEXXEECC.BBAATT to /aauuttooeexxeecc.bbaatt in your COHERENT root partition:

163: dos xa /dev/at0a /autoexec.bat

166: You will want to use the aa switch any time you are transferring a
167: text file.
168:
169: Suppose that the second partition on your first hard drive
170: (COHERENT device /ddeevv/aatt00bb) is an extended MS-DOS partition with
171: two logical drives, DD: and EE:. To copy a COHERENT text file
172: /ttmmpp/ffoooo to DD:\TTMMPP\FFOOOO, use the command
173:
174:
175: dos ra1 /dev/at0b /tmp/foo
176:
177:
178: To copy non-text file ffrroottzz in the current COHERENT directory to
179: MS-DOS file EE:\DDBBFF\AAXX\FFRROOTTZZ, use the command
180:
181:
182: dos rp2 /dev/at0b dbf/ax/frotz < frotz

191: ddooss does not work with MS-DOS hard-disk file systems that hold
192: more than 64,000 clusters (i.e., with four-byte FAT entries
193: rather than 1.5-byte or two-byte FAT entries). It does

204:
205: understand MS-DOS 3.3 extended disk partitions (where a single
206: partition contains more than one MS-DOS file system), but you
207: must know whether a partition contains a normal MS-DOS partition
208: or an extended partition.
209:
210: ddooss does not check for unusual characters in a COHERENT file name
211: or for file names that differ from other file names only in case.
