dos

copy, the Chinese meaning is "copy", A command that is easy to understand by name. Its function is to copy files. Its usage is very simple: copy the source file destination path.

Suppose you need to copy the file d:\test\test.txt to the root directory of drive D, then you can easily do it by using copy d:\test\test.txt d:\.

Of course, this is the simplest situation. In actual use, you will still encounter very complex situations.

If there is already a file named test.txt in the root directory of drive D, then when copying it, the copy command will prompt you whether to overwrite the original file, give up copying, or overwrite all files. If you overwrite all the original files when copying in batches, it will be very troublesome to select one by one. At this time, you can use the parameter /y to overwrite the original files without prompting (equivalent to automatically selecting the Yes option), complete The command is copy /y d:\test\test.txt d:\ .

If you need to rename the source file when copying, for example, when changing test.txt to 1.txt, you can use it directly: copy d:\test\test.txt d:\ 1.txt command, that is to say, when specifying the destination path, directly specify the file name, then the new file name will be the name of the source file after copying it.

If the path to be copied contains special characters such as spaces and &, please use quotation marks to enclose these special characters, for example: copy "d:\test abc\test.txt" "d:\ t&est"

In addition to the function of "copying" files, the copy command also has a unique skill: merging multiple files into one file. The specific format is: copy file 1 file 2 file 3... Destination path\new file name. For example: copy d:\test.txt d:\abc.txt d:\test\test.txt, then merge the contents of the two files test.txt and abc.txt in the root directory of drive D into test. txt and save it to the d:\test directory.

Copy also has some parameters, but the commonly used ones are the above. For more usages, please use copy /? in the command line window to query. It is easy to get started.

It must be noted that copy can only copy files. For copying folders, you need to use xcopy to copy. xcopy is an advanced version of copy. It has richer parameters and can achieve more complex functions. It can copy all files and folders. It will be introduced separately in the future and will not be explained here.
