反比例函数切线:DOS启动盘的一个问题

来源:百度文库 编辑:杭州交通信息网 时间:2024/04/30 14:30:02
本人小鸟一只,一直是用的以前那种DOS系统,
大家都知道现在的XCOPY命令里带参数/S /E 的话就可以把拷贝子目录下
所有的文件,我在XP的系统下试过了但不是纯DOS,是用的命令提示符.
之后我用的我的启动盘启动电脑在DOS下使用XCOPY /S /E 这个命令,可是不行.我的启动盘里的DOS好像不支持这个命令.
(我的启动盘是ME系统下制作的.DOS版本不是很高).
现在小弟想请教那个高手可以告诉我.那种版本的DOS才能在纯DOS
支持XCOPY /S /E 这个命令.
小弟在这里先谢谢各位大侠了.

The command-line options

F-PROT.EXE is usually run without any parameters and will then enter
interactive mode, but if the /HARD option is used, or a drive, file or
directory is specified规定, it will enter command-line mode.

Syntax for command-line mode: F-PROT [drive, file or directory] [options]

The available command-line options are

/APPEND
Appends the report to an existing file (Only used with /REPORT(report)).

/ARCHIVE=n archive=n
Scans inside .ARJ, .CAB, .LZH and .ZIP archives档案 . F-PROT currently
supports only RAR archives created by RAR 2.5 and older - support for
RAR 3.0 will be added soon. The parameter n specifies(具体的参数n) how many levels
(archives inside archives) to scan.

/AUTO
May be specified with /DISINF, /DELETE or /RENAME so F-PROT will not
request permission before rremoving each virus.

/BEEP
Produces an annoying beep when a virus is found. NOT recommended when
scanning a virus collection.

/COLLECT
Assumes what is being scanned is a virus collection, where viruses might be
found in "abnormal" locations. In particular, selecting this option will
enable detection of file images of boot sector viruses. This switch also
provides the same features as the old /GURU option. Note that using /COLLECT
will slow down the scan.

/DELETE
Deletes infected感染 files.

/DISINF
Disinfects 消毒 whenever possible. It is possible to specify the following
combinations of switches:

/DISINF /DELETE
Disinfects when possible, otherwise deletes infected files.

/DISINF /RENAME
Disinfects when possible, otherwise attempts to rename infected COM/EXE
files to VOM/VXE.

/DISINF /RENAME /DELETE
Disinfects when possible, otherwise attempts to rename infected COM/EXE
files to VOM/VXE, but if that fails the files are deleted.

/DUMB
Does a "dumb" scan of all files. This option is often not necessary,
and /TYPE can be used instead. The only cases where it might be needed are
the following:

If you are scanning a virus collection, where infected files have
non-standard extensions, such as .VOM instead of .COM, they will not
be scanned for viruses, unless this switch is specified.

If you are cleaning up a virus infection you should use this
switch.

/EXT
By default F-PROT will open every file and try to determine its type,
so it will for example scan Word files, even if they do not use a DOC/DOT
extension. By using /EXT the scanning can be speeded up slightly as F-PROT
will then only scan files with "default" extensions.

/FREEZE
"Freezes" the program if a virus is found anywhere.

/HARD
Scans all files on all hard disks in the computer.

/HELP
Displays the list of command-line options.

/INTER
Forces the program to enter interactive mode, even when a path, directory
or file name is given on the command line.

/LIST
Lists all files that are scanned.

/LOADDEF
Load the DEF files into memory.

/NOBOOT
Does not scan boot sectors.

/NOBREAK
Disables ESC and ^C during scanning.

/NOFILE
Does not scan files. Only useful if you cleaning up a boot sector infection
and do not want to spend unnecessary time scanning files.

/NOFLOPPY
For use on systems without floppy drives.

/NOHEUR
Version 3 has a smaller, more reliable set of heuristics than version 2,
but they are enabled by default, unlike version 2. This option allows
you to turn the heuristics off.

/NOMEM
Does not scan memory for viruses. Not recommended, unless you are
absolutely certain that no viruses are present in memory.

/NOSUB
Does not scan subdirectories.

/PACKED
Scans "inside" various types of compressed executables (PKLITE for
example), by emulating the execution of the decompressor. As this option
can slow the scan down significantly, we only recommend using it when
scanning new software before installation.

/PAGE
Pauses after each page (command-line mode only).

/REMOVEALL
Removes all macros from all documents. Useful if you encounter a new
macro virus, and you know that the document did not contain any macros
before it got infected.

/REMOVENEW
If a new variant of a macro virus is found in a document, all macros are
removed from that particular document.

/RENAME
Renames infected COM/EXE files to VOM/VXE. If files with those
extensions already exist, .VVV is used instead. Infected document files
are not renamed, as that would be pointless - they would be equally
infectious afterwards.

/REPORT=file
Sends the output to a file, in addition to displaying it on the screen.

/SAFEREMOVE
Removes all macros from documents, if a known virus is found.

/SERVER
Enable mail-server heuristics. Will for example complain about encrypted
executables inside archives.

/SILENT
Does not generate any screen output (command-line mode only).

/TYPE
Scan every file, but skip those which do not seem to contain executable
code. This is faster than /DUMB but less thorough.

/VIRLIST
Produces a list of known viruses, as well as information on whether they
can be disinfected.

/VIRNO
Counts the known viruses and reports the total.

/WRAP
Wraps text so the report fits in 78 columns.

The program uses the following exit codes, which can be checked with the
ERRORLEVEL command from a BAT file.

只要有XCOPY这个文件的DOS就支持XCOPY

XCOPY这个文件的DOS就支持XCOPY
