NAME [Toc] [Back]
doschmod - change attributes of a DOS file
SYNOPSIS [Toc] [Back]
doschmod [-mu] mode device:file ...
DESCRIPTION [Toc] [Back]
The doschmod command is targeted for removal from HP-UX; see the
doschmod is the DOS counterpart of chmod (see chmod(1)).
Options [Toc] [Back]
doschmod recognizes one option:
-m If an ordinary file with the same name as volume label
exists, operation will be performed on the file instead of
-u Disable argument case conversion. In the absence of this
option, all DOS file names are converted to uppercase.
A DOS file name is recognized by the presence of an embedded colon (:)
delimiter; see dosif(4) for DOS file naming conventions.
Metacharacters *, ?, and [ ... ] can be used when specifying DOS file
names. These must be quoted when specifying a DOS file name, because
file name expansion must be performed by the DOS utilities, not by the
shell. DOS utilities expand file names as described in regexp(5)
under PATTERN MATCHING NOTATION.
The attributes of each named file are changed according to mode, which
is an octal number in the range 000 to 0377. mode is constructed from
the logical OR of the following modes:
200 Reserved. Do not use.
100 Reserved. Do not use.
040 Archive. Set whenever the file has been written to and
020 Directory. Do not modify.
010 Volume Label. Do not modify.
004 System file. Marks files that are part of the DOS
002 Hidden file. Marks files that do not appear in a DOS
directory listing using the DOS DIR command.
001 Read-Only file. Marks files as read-only.

TO BE OBSOLETED
Specifying inappropriate mode values can make files and/or directories
inaccessible, and in certain cases can damage the file system. To
prevent such problems, do not change the mode of directories and
Normal users should have no need to use mode bits other than 001, 002,
EXAMPLES [Toc] [Back]
Mark file /dev/rfd9122:memo.txt as a hidden file:
doschmod 002 /dev/rfd9122:memo.txt
Mark file driveC:autoexec.bat read-only:
doschmod 001 driveC:autoexec.bat
