在Windows命令中将两个文件合并为一个文件只会导致第一个文件被复制

Question

This should be a fairly straightforward operation, but I'm puzzled as to why it is not working.

The following commands in windows results in only the first file being copied to destination file report.rtf

copy /b *.rtf report.rtf

or

type *.rtf >> report.rtf

Answer 1

If you want to add a second file to an existing file, try

copy /b report.rtf+secondFile.rtf report.rtf

The "+" should combine them (assuming by "combine" you mean "concatenate").

Changing the report.rtf at the end to another file will let you put them into a new file, of course.

NOTE: In Windows 8.1 (and probably Windows 7 and Windows 8) doing this as a normal user will not work! Instead, run cmd.exe (command prompt) as an Administrator (right-click, Run as Administrator).
