Isn t it a master if you don t master DOS commands well?

DOS is basically useless for ordinary computer students nowadays!

You don't play as well as the computer.

It's just that after learning DOS, in a more in-depth study of the computer, there is an effect of drawing inferences!

Yes, DOS is the foundation of learning computers, just like learning martial arts must be done well.

As long as you use dos for file manipulation, you can learn the meaning of dos commands.

Although it is not used a lot, it is recommended that it should be taken seriously.

This is not necessarily, it depends on what kind of master you want to be.

If it's assembly and language, a little bit of DOS is fine; If it's maintenance or security, it's going to be deeper.

A few basic things to know on the line,In fact, the WIN era has not relied on the existence of DOS,DOS must still learn in terms of installation and some data recovery,For novices to skip this aspect,When you use it in the future,Interest first,Don't let boring things kill your interest,Learn things badly,Let alone become a master。

Your concept of being a master is too vague. DOS commands are now useless except for a few commonly used ones. Besides, if you want to be a master of DOS, you can learn DOS, there are too many kinds of masters, right?

Windows master、Photoshop master。。。

Square brackets: optional parameters.

Parentheses: Subparameters under optional parameters.

For example: md[drive letter:][pathname] subdirectory name

md C: Windows Temp 123 drive letter C: pathname Windows Temp subdirectory name 123

An asterisk is one of the wildcards that represents any of them. What are the other wildcards? Question mark:

Represents an arbitrary character. For example: dir c:

.txt is the list of all extensions under the c: packing.

txt. Another example: dir c:

a???It is a file that lists the arbitrary extension of the c: disk followed by three arbitrary characters starting with a (assuming the result is c:

c:\ c:\。

It is relatively rare, and should be understood as a set of parameters with different conditions for the same parameters that can be executed one after another.

For example: scandisk [drive letter 1:][ all].

Example: scandisk c: d: e: f: all

In fact, learning DOS is very simple. These symbols other than the * asterisk are just to help you understand the usage of the various parameters of the command, and do not have to be rote memorization. And in today's Windows 7 is very popular, although learning DOS commands is not useless, but it doesn't have to be like I learned a lot of internal commands and external commands back then.

It is enough to master internal orders. Will use dir cd md rd del copy xcopy format type these are almost enough. Moreover, these commands have been upgraded with a lot of parameters in the 32-bit command line prompt mode, and there is no point in learning the commands by death.

It's better to learn commands under linux.

Dos is no longer easy to find.

If you are on an XP system, click Run in the Start menu, type CMD, and enter the DOS interface.

I think it should be able to... But I won't... But the general dos I still will...

The topic of invasion is not appropriate here.

To put it simply, the use of computers should be 'spiritual', there is no most mysterious command, only the most effective command, and the key is still in the hands of the user. Study hard, work hard to improve your computer level, and flexibly use the services and command programs provided by various systems to be able to solve all kinds of problems.

1. CLS clears the screen.

Example: C: > CLS

2. Dir column disk directory.

Example: C: > diR

3. CD directory operation.

Example: C: > CD Windows (enter the subordinate directory) C: > cd...(Back to the parent directory).

4. MD creates a new directory.

Example: C: > MD 123

5. rd delete the directory.

Example: C: > rd 123

6. del delete the file (note that the usage of the rd does not use del is a file operation and rd is a directory operation).

Example: C: > del

7. Copy directory Cobe (also the copy that win says) Example: C:> Copy C: D:

Rename the C-drive Cobe to the D-drive.

8. Move directory move (also the cut that win said) Example: C:> move"c:\4 " "d:\78 "

Cut 4 from C to D and rename to 78

9. REN file name change (invalid for folder).

Example: c:> ren c: c:

10. format command.

Example: C:> format C:(Format C disk)11, check

Example: C: > check f to detect errors in the C drive.

Install the system based on the most basic partitions fdisk, format format, view files dir and so on.

What's the use of learning this stuff besides?If you're already using Windows, see Help!

If you want to have data inside, try Easy Recovery, which can read RAW format and even partition corrupted hard drives (including portable hard drives).Note that the computer with Easy Recovery is installed, it is best to connect the mobile hard disk after installation, and then the system backup and restore is temporarily closed, otherwise it is possible to write data to the mobile hard disk and damage the original data.

cmd？What you said about forcibly formatting the format ??Q Can you try specifying the partition and format? Your problem description is not clear, how big is the portable hard drive?Is there a partition?And then every partition prompt is the same?

If you don't want the data, or have backed up your data with a restore like Easy Recovery. If you can't use the information in the system, you can try to boot it with a disc or USB flash drive, and use those installation tools to repartition and format the mobile hard disk.

Buy a book that teaches DOS to learn it yourself or look up tutorials on the Internet.
