Windows 10: Simple batch file gets syntax error

My one-line batch file gets the error message :The syntax of the command is incorrect. I'm pretty sure this is not so.As in so many many other cases, Microsoft gives a generic error message that has no apparent connection to what the user is trying to do. As a result, we don't know what is going on, and we don't know what to do. So we have to waste the time of a Microsoft representative, and maybe get an answer in a couple of years.And it's even longer for a CORRECT answer.Here's my batch fileecho offcopy C:\Users\larry\OneDrive\Pictures\user.png C:\ProgramData\Microsoft\User Account Picture

Batch rename files using ForFiles command getting syntax error

Win 10

I want to rename a bunch of files to add a prefix. ie "aaa.url" to "win 10- aaa.url"

I found these pages:

Rename file extensions in bulk from command line [CMD]

Forfiles

the example and my version of the command

forfiles /M *.jpg /C "cmd /c rename @file \"@fname - pic.jpg\""

forfiles /M *.* /C "CMD /c RENAME @FILE \"WIN 10- @FILE\""

I get this output:

D:\Public\Favorites\@test>forfiles /M *.* /C "CMD /c RENAME @FILE \"WIN 10- @FILE\""

As far as I can see I have the syntax OK, but obviously windows does not agree with me.

What am I missing?

 

Batch File Syntax: Insert %USERPROFILE% into batch file command lines

Following batch file code lines work fine.

Batch File that works:

CD "C:\Users\xlmas\Documents\Visual Studio 2013\Projects\ToolsNET\bin\Release\"

"C:\Users\xlmas\Documents\Visual Studio DOS Utilities\RegAsm64" "C:\Users\xlmas\Documents\Visual Studio 2013\Projects\ToolsNET\bin\Release\ToolsNET.dll" /UNREGISTER

Goal:

Want to substitute the environmental variable %USERPROFILE% for "C:\Users\xlmas" but I keep running into syntax issues. The issue seems to be related to the spaces in the Path. I have attempted the code with and without quotation marks. Either way there
are syntax errors when invoking RegAsm64. If I include quotation marks (to preserve the folder name with spaces) in the Set commands they screw up attempting to run RegAsm64.

Failed attempts:

Set DLLPathEnd="\Documents\Visual Studio 2013\Projects\ToolsNET\bin\Release"

Set DosUtilEndPath="\Documents\Visual Studio DOS Utilities"

Set DLLFullPath=%UserProfile%%DLLPathEnd%

CD %DLLFullPath%

Set DosUtilFullPath=%UserProfile%%DosUtilEndPath%

%DosUtilFullPath%\ResAsm64 %DLLFullPath%\ToolsNET.dll /UNREGISTER

Any thoughts greatly appreciated!

 

Batch Files Knowledge Base

Batch files are exactly that. They are a file that contain a "batch" of commands so that you do not have to type them consecutively at a DOS prompt.

Anything that you can do at a DOS prompt you can do in a BF, and more.

What batch files allow you to do is take arguments when you call the file using the % identifier within the batch file, and also to use conditional statements (if's) to cause code redirection based on user input.

Batch file syntax is really easy to learn, and in a day or two you can write very powerful batch files to do a lot of stuff.

They are not so much useful to the home user as they are to someone who is an administrator of a network.

A simple use of a batch file ...

Let's say that you have a system that has 3 hard drives. C:, D:, E:
You want to copy the contents of C & D to E.

You create a file called MyCopy.cmd (just make a text file in notepad and rename it)
Then type in two lines.
"xcopy C:\ E:\MyCopyOfC /c /e /r /k (etc. xcopy siwtches
"xcopy D:\ E:\MyCopyOfD (switches)

Save the file and run from a DOS prompt.

This will create two directories (if the switches are correct) called MyCopyOfC and MyCopyOfD on the E: partition.

This is a simple backup solution for multiple hard drives.

You can , of course, get as elaborate as you want.
