Copying Files Using the Command Line

If you don't mind doing a little more typing and a little less mouse clicking, you can perform a lot of actions from the command line. (Displaying the Command Prompt window is covered under another tip.) One thing you can do from the command line is to copy files. The command-line copy command is COPY and it takes two (or more) parameters. The first parameter specifies the file that is to be copied, and the second parameter specifies to where the file should be copied. So let's say you have a file called "C:\Temp\BatFun.bat" and you want to copy it to "C:\Bat\BatFun.bat". You would type the following at the command line:

C:\> COPY C:\Temp\BatFun.bat C:\Bat\BatFun.bat

The BatFun.bat file in the \Temp directory remains there and a copy of it is created in the \Bat directory. Of course, you can specify whatever name you like for the destination, so you may have a \Temp\BatFun.bat file that you're developing and testing, but once you're satisfied with it you may want to copy it to your \Bat directory and give it the name of DirList.bat. This is accomplished by just changing the name of the destination parameter:

C:\> COPY C:\Temp\BatFun.bat C:\Bat\DirList.bat

You can use wildcard character to copy multiple files at a time. So let's say you have several .bat files in your \Temp directory that are supposed to work together, and you want to copy them all to your \Bat directory. Maybe the files are named C:\Temp\Dir1.bat, C:\Temp\Dir2.bat, and C:\Temp\Dir3.bat. To copy them all to your \Bat directory the command would be:

C:\> COPY C:\Temp\Dir?.bat C:\Bat

The wildcard character "?" stands for exactly one actual character in the source parameter. Note that you didn't need to specify anything except the destination directory (without the trailing backslash) as the second parameter. This is because COPY automatically uses the file name specified by the first parameter as the file name to be used in the \Bat directory. In other words, you'll end up with a Dir1.bat, Dir2.bat, and Dir3.bat in your C:\Bat directory.

The COPY command can also be used to concatenate (combine) files. This is done by specifying the files that are to be concatenated as the source parameter but separated by plus signs. Then you give exactly one file name as the destination parameter. All of the files separated by the plus signs will then be appended to one other, it the order specified, and that concatenated file is created where the destination parameter indicates.

So perhaps you have a few text files in your C:\Temp directory called Text1.txt, Text2.txt, and Text3.txt. You want to concatenate them into a master file (we'll also put it in your \Temp directory) called TextAll.txt. This can be done by using the following command:

C:\Temp> COPY Text1.txt+Text2.txt+Text3.txt TextAll.txt

Or you can give your fingers a break and use wildcards to achieve the same purpose:

C:\Temp> COPY Text?.txt TextAll.txt

So you don't technically have to use plus signs to separate the source files. In reality you just need to have multiple source files (whether separated by plus signs or indicated via wildcard characters) and exactly one destination file.

As with most command-line statements, there are switches that can be used with the COPY command in order to specify certain types of behavior. You can display the full syntax for the command by just invoking it and appending the "/?" switch like so:

C:\Temp> COPY /?

By looking at this output you can specify "/Y", for example, to tell COPY not to ask you about overwriting an existing file.

It is reassuring to know that despite all of the "advancements", the DOS commands and most of the keyboard shortcuts still work from the 80's. Never have liked having to remove my hand from the keyboard for mouse input.
