attrib -a a:*.bak
xcopy a: b: /a 将A盘上的所有标志为"归档"属性的文件拷到B盘xcopy a: b: /m 将A盘上的所有文件拷到B盘后并移去归档属性三、cd 介绍: cd...返回上二级目录"."代表当前目录"."代表父目录cd ..\..返回到上级目录的父目录(祖目录)
cd A:\ 将A盘的当前目录改为根目录
cd A:\xx 将A盘的当前目录改为子目录xx下
cd ..\98 先返回父目录,再进入父目录下的98子目录
cd ..返回到父目录
cd\98 进入根目录下的98子目录
四、copy [/y][/-y][/v][ /B]
copy /y 不加提示,对所有文件加以覆盖
/-y 加以提示,对所有文件(yes或no提问)
/v 拷贝以后加以校验
/B 按二进制进行显示
copy w1.wps con/b 可以将wps文件在屏幕上显示,而不必进入wps状态copy ..\98 将父目录下的98子目录下的所有文件全拷到当前子目录
copy .\97 当当前目录下的97子目录下文件全部拷到当前目录
copy . c:\ 将当前目录下的所有文件拷到c盘根目录
. 意味着*.* 文件
copy nul a.abc 将a.abc 文件清空(文件长度改为0)
copy 文件名+con 向文本文件中追加命令或内容
copy con 文件名创建文本文件(F6存盘退出)
copy con prn 检测打印机的开关
五、xcopy命令
xcopy [source] [d:date] [/p] [/s] [/e] [/v] [/y]
xcopy [d:date] xcopy a:b:\ /d:08/18/98/s/v 拷贝98.08.18年后的文件xcopy [/p] 提示创建子目录
xcopy [/s] 连带子目录一起拷贝. 注意:若目标盘上不存在此子目录,而在目标盘的结束符又不以"\"为结束,则将提示:
does destination specify a file name or directory name on the target [f=file,d=directory]?
在目标盘上创建文件[按下]还是创建子目录[按下d] ?应选择d键
xcopy[/v] 带较验
*:(1) xcopy 不拷贝系统和隐含文件,应先予以修改属性再拷贝
xcopy [/y] 覆盖时是否有提示, /y 不带提示
若省略目标盘或子目录名,则拷贝到当前目录下
六、del /p
加/p 可以在删除前是否提示
如del后加子目录名,则将子目录下所有文件(隐含.系统.只读文件除外)全删除,
加/p则可以确认.
七、undelete [name] /au
不加提示地将所有满足条件的文件恢复(能够恢复的),并将首字母置成"#",若已
存在,则按"# % & 0 1 2-9 a-z"顺序加上.
如:undelete *.dbf/au 将扩展名为"dbf"的文件全恢复,并以"#"开头,作为文件名, /list 仅列出可恢复的文件,而不恢复
undelete /load 将undelete装入内存
/unload 将undelete卸出内存
/s[drive]对指定驱动器进行监测管理
undelete/sc
将undelete驻留内存,?并创建一个隐含的sentry 子目录对c盘删除的文件进行管理undelete/ds 恢复
相应恢复命令可以用undelete即可完整恢复出文件名(非常完整)
最常用undelete *.*
deltree /y [drive:path]
deltree 删除子目录及文件,尽管有些文件是系统文件或隐含文件
它可以带有通配符,带有通配符时,它将删除符合条件的文件及子目录
如:?undelete *.dbf/au 将扩展名为"dbf"的文件全恢复,并以"#"开头作为文件
名.
/list 仅列出可恢复的文件,而不作恢复操作.
undelete/load 将undelete 装入内存.
/unload将undelete 卸出内存.
/s[drive] 对指定的驱动器进行监视管理.
undelete/sc 将undelete 驻留内存,并创建一个隐含的sentry子目录对C盘删除的文件进行管理.相应恢复命令可以用undelete/ds 即可完整恢复出文件名(很完善). 最常用的是undelete *.*
八、deltree /y [drive:path]
deltree 删除子目录及文件,尽管有些文件是系统或隐含的.
它可以带有通配符,这时它将删除符合条件的文件或子目录.
如:存在L1文件,L2子目录,L3文件,L4子目录
deltree L*.* 将删除以上所有的文件和子目录,但在删除前加以确认,若不删除,
可以输入"N".
/y 参数是在删除时不加以确认就进行操作的.
它删除的文件可以用undelete恢复,?但不能恢复子目录及其下的文件,可以用特
殊工具.如NORTON 8.0 等.
若提前使用了undelete/s,?则可以在sentry子目录下找到完整的文件,但名已经
改变了.
九、dos=high[|low[umb|noumb]]
dos=high,umb 则dos将自身装入高端内存(high)并能管理上位内存(umb).
noumb 则不管理上位内存.
在写入dos=high及umb 前应装入device=himem.sys
为了将程序或驱动程序装入上位内存,必须使用dos=umb,可省出大部分常规内存.
可以在config.sys的任何位置写上dos=high,umb
若显示hma not avoiable 或load down low 则表明不能使用高端内存.
十、doskey 记录以前敲过的dos命令,可以用F7来显示,用"↑↓"来选择,用F9来输入选择的命令号.
doskey/restall 重新装入一次,以前的命令行撤消.
doskey/history 显示内存中所有的命令,可以">"显示到其它文件中,缩写"/H". doskey dir=cls 则击入dir等同于cls一样.
doskey/macros 可显示所有的宏定义,可使用">"重定义到文件中,可缩写"/M". doskey dir= 可撤消对dir 的宏定义.
doskey p=dir$tdir*.exe/p$tdir c:\t$tdir c:\t$*
$t为命令的区分符,而$*为命令的结束符
doskey/insert(overstrike)?在重新输入命令时,对旧命令的修改是插入还是覆
盖状态(默认).
十一、emm386.exe
提供对扩展内存的管理,使应用程序象使用常规内存一样能够使用它.
常见的用法是在config.sys 中
device=c:\dos\himem.sys
device=c:\dos\emm386.exe ram
d=64 将DMA 内存数量设置为64K
noems 提供对上位内存的访问,但不提供对扩展内存的访问.
应注意的是在windows中最好不要用它,因为windows本身有对扩展内存进行管理的程序.应采用windows中的管理器.
十二、fc 命令fc/b dt.dat dt2.dat>b (作二进制代码比较)
比较两个文件,一般用作存取进度,修改游戏存储文件用.
实际代码位置应加上0100 如:0000 05E4:00 67
实际用debug -e 修改时应加上0100 即0000 06E4:00 67
后面加上重定向文件">P" 可以将比较结果输出到p文件中.
十三、format /q /u /s /n:sectors /f:size /c
/q参数:快速格式化,仅扫描文件分配表和根目录区,仅对格式化过的磁盘有效.
使用时应确保格式化过后没有增加新的坏道.
/u参数:无条件格式化,并且不保存原来盘上的信息,可以防止"unformat".
/s参数:格式化为系统盘,也可以使用"sys"命令.
/f:size size 可以为160 180 320 360 720 1200 1440 2800
/n:sector n可以为1 格式为单面盘,容量为160k 180k
可以为4 可以在5寸高密驱动器上格式化360k磁盘
可以为8 可以在5寸高密驱动器上进行8个扇区的格式化.
/c 重新测试坏扇区,缺省时如果一个扇区标记为"坏",以后格式时就不在从新测
试,仅作标记,使用"/C"时可以从新测试.
十四、unformat 命令
对用format 格式过,且未用"/u"参数的命令起作用,用它可以来重新修复已经损
坏的硬盘分区表,但对网络盘不起作用.
unformat drive:[/l][/test][/p]
/l 显示每一个被unformat发现的文件和子目录,如果没有这个开关,只显示那些
破碎的文件和子目录,可以用ctrl+s 暂停,按任意键继续.
/test 仅作一个测试,不作实际的修复工作,作模拟过程.
/p 一边测试一边打印.
注:这种方法不能保证修复所有的文件,尤其是格式化后又添加过数据的磁盘.
恢复后的文件依次存放在subdir1....2....3等子目录中.
十五、interlnk 语法interlnk g=e ,它可以通过串口或并口在两机间进行通讯. 将服务器端上的e驱动器映射为客户端的g驱动器,以后对客户端而言,所有对g的操作都意味着对服务器的访问,取消映射的办法为interlnk g=
单独输入interlnk 则显示所有的映射情况.
注意:interlnk 必须在装入interlnk.exe 设备驱动程序才可以使用.
所用的驱动器符号与config.?sys中lastdrv.exe设置的数目有关.可以作一个一
端为25针,另一端为9针的串行线实现,具体接线方式如下:
5 - 7 2 - 15
3 - 2 3 - 13
7 - 4 4 - 12
6 - 6 5 - 10
3 - 3 6 - 11
8 - 5 15 - 2
4 - 20 13 - 3
9针25针12 - 4
10 - 5
11 - 6
25 - 25
25针25针
十六、interlnk.exe 与intersvr.exe
interlnk.exe 重新定向对于客户驱动器或打印接口的请求到另外的服务器驱动
器或打印机.
语法:config.sys 中加入:
device=c:\dos\interlnk.exe [drive:n][/noprinter][com][lpt]
十七、memmaker[/b][/batch][session][/swap:drive]
使用memmaker能够优化内存配置,?并将配置写入autoexec.bat和config.sys中.
在这一过程中,需要重新启动几次机器.
十八、memitem memcolor memdefault submenu 菜单选项include autoexec.bat 中如下: config.sys中如下:
path c:\dos;c:\ucdos [menu]
doskey menucolor=15,1(前景色15,背景色1)
\mouse\mouse menuitem=base_config,this is a base
goto %config% ->选择项menuitem=cced_config,this is a cced 选项提示
:base_config menudefault=base_config,5
goto exit ->跳出缺省为base_config,延迟时间5秒
:cced_config [common]
c:\dos\smartdrv.exe /l device=c:\dos\himem.sys
goto exit 各项都包含的共同部分
:exit ->结束[base_config]
device=c:\dos\emm386.exe ram
dos=high,umb
[cced_config]
device=c:\dos\smartdrv.exe/double_buffer
include=base_config 包含base_config设置
可以根据计算机的在不同情况下的配置要求来选择.
十九、mscdex.exe 提供对光驱进行读写的程序
mscdex/d:drive [/D:drive][/e][/k][/s][/l:letter]
典型:config.sys 中device=c:\cdrom\cdrom.sys /d:mscd000
autoexec.bat中c:\dos\mscdex /d:mscd000 /l:g
配置了一个光驱,符号为g
参数/d:drive1为光驱身份号,须与config.sys中的符号一致,可有多个
/d:mscd000 /d:mscd001
/e:使用扩展内存装入光驱驱动程序.
/s:使光驱在ms_net或windows是否设置为共享光驱
/V是否在加载时显示内存.
/L:letter 分配给光驱的盘符
/m:number 指定缓冲器的数目
应该注意的是:?如果用smartdrv.exe 加速对光驱的读写能力,应该在autoexec.
bat中将mscdex.?exe 写在smartdrv.exe 之前,smartdrv.exe的使用可大幅提高
对驱动器的读写能力.
二十、msd的使用
使用msd 可以整体检查计算机配置及系统信息
包括:?驱动器参数,计算机cpu参数,内存大小参数,显示器类型,串.并口情况,以及各个IRQ 占用情况,据此可以分析新增设备是否与原来设备有冲突.
同时也可以通过分析内存驻留程序,判断内存中是否有病毒,有则标为"???".
二十一、prompt dos提示符
$q 等于号$t 当前时间$d 当前日期$p 当前驱动器符号
$$ $号提示$n当前驱动器$g 大于号$l小于号$b 显示"|"管道号
$h 隐去提示符$E显示"<-"号
对于其它文字,则直接显示文本本身prompt ljw,则显示为ljw提示符
prompt 则仅显示当前驱动器号及大于号.
二十二、ramdrive.sys 使用内存当做虚拟盘来使用
应注意,所有数据都存在于内存中,应及时将其存到硬盘中,否则掉电后或者死机
后将丢失全部数据,优点是运行速度快,但不能在windows中使用.
示例:config.sys: device=c:\dos\ramdrive.sys /size[/e|a]
size为以k为单位的字节数,即建立的虚拟盘的大小.
/e或/a 都是使用扩展内存来建立虚拟盘,?加参数的前提是必须先加载内存管理
器himem.sys及emm386.exe.
二十三、subst 将一个驱动器与一个子目录联接
如:将对A:\l1\l2 子目录的请求映射为S盘,则输入
subst s: a:\l1\l2 即可
这样使用dir s:?等命令则显示的是a:\l1\l2子目录下的内容,其它copy del 一样可以用subst s: d 来取消这种映射.
可以用subst 来显示各种联接情况
注意:?可以采用subst a: c:a 来建立一个对于A的读写盘.对于某些安装软件
来说,?必须使用A盘来安装,就可以使用先将所要安装的软件全部拷贝到C:a子
目录中,然后输入subst a: c:a,再转到A:,就可以进行软件的安装了.
二十四、mem /c /m /p /d 常规内存显示程序
/c显示所有内存驻留程序的占用情况,分为conventional常规内存和uppermemory 高端内存占用,并显示总的占用情况(常规高端保留扩展内存)
/p分页显示,页间暂停
/m后加模块名如:/m msdos 显示dos系统内存的占用.
/d对常规高端保留扩展内存加以详细例表说明
通过分析,可以看出内存占用是否合理,以及各种程序是否正常加载,从而在此基
础上使用内存优化工具memmaker进行各种管理,同时又可以分析出一些程序死机
的原因,若有的地方显示"???",则可以断定内存中有病毒的存在,有利于发现及消灭.
二十五、各种管道工具的使用"> < >> <<"
将各种命令造成的输出或所需要的输入重新定向
如:dir *.bat /b>p 可以将dir *.bat 例出的文件名输出到p文件中.
time
>p.bat
p文件中仅存在一个回车符,则可以将时间追加进p.bat文件中
"> >>" 是将命令产生的输出重新定向,比如到文件或打印机中.
>>产生的内容将追加进文件中,>则将原文件内容覆盖.
"< <<" 是将命令所需要输入的内容重新定向.
如:time
需要说明的是"prn "为打印机, "null"为空设备
con 为显示器
type p.bat>prn 可将p.bat打印出来.
copy null p 可将p文件删除掉
copy con p 可以在屏幕上编辑p文件,F6可以存盘退出
type p>pp 完成p文件到pp 的复制
type p|more 可在屏满时暂停显示
二十六、move 命令
move [y/-y] filename1 filename2
将文件1移动到文件2处
如:move c:\dos\*.* c:\cced
将dos子目录下的所有文件全部移动到cced 子目录下
/y|-y参数在目标目录不存在需要创建时,是否出现提示
可以使用该命令修改子目录名称,如move dos cced
将dos目录名改为cced
二十七、append 指定一些特殊数据文件的存放位置,如user.dat pe2.pro等一些非*.
exe *.com *.bat 文件
格式:append [:]终止以前存在的指定目录append 显示指定情况
append [path] append c:\user 等
二十八、
call 在一个批处理命令中调用另外一个批处理文件
(1)不终止现有文件的运行,执行完掉用程序后立即返回.
(2)被调用批处理命令必须以bat 为扩展名
(3)调用批处理文件时,可以加上参数(%1-%9)以及环境变量如%baud%
(4)不能使用管道工具及重定向工具
二十九、device devicehigh loadhigh
device 将指定的设备驱动程序装入内存中
devicehigh将指定的设备驱动程序装入高端内存中
loadhigh 将指定的设备驱动程序装入高端内存中
三十、defrag 优化磁盘
legend(传奇) optimize(优化) elapse(逝去) fragment(碎片)
该命令执行对指定的盘进行优化处理(包括检查文件分配表,各文件状态,纠正错误),在执行时,可按照文件名大小,时间,扩展名对文件进行排序.

高中英语作文：广告的利与弊
高中英语作文：广告的利与弊 导读：本文高中英语作文：广告的利与弊，仅供参考，如果觉得很不错，欢迎点评和分享。 With the development of advertising, ads have been connected with people’s life. Is it good or bad? We had a discussion. Some people think advertisements don’t tell the fact about the products advertised. Also, they take up too much time on TV and the radio, and cover too much space in newspapers and magazines, which waste a lot of paper. What’s worse, there are some false advertisements that cheat people into buying their things. Therefore, they believe advertisements should be stopped. Some other people think advertisements can help us make better choices about what to buy by offering us the latest information about various goods. Moreover, many well-done advertisements are popular and entertaining, which appeal to the consumers. However, too many advertisements can be annoying. So we should develop advertising properly. In my opinion, ads is like a two-side sword. Anyway, we can be wise if we are able to distinguish between fiction and fact. 随着广告业的发展，广告已经与人们的生活联系在一起。广告是好还是坏？我们进行了一个讨论。有些人认为广告没有告诉关于这个产品的实际。同时，广告在电视和收音机上占用了太多的时间，在报纸和杂志上也占用了太多空间，浪费了很多纸。更糟的是，一些虚假广告欺骗人们去买他们的东西。因此，他们认为广告应该被取缔。
