svn head revision from a remote repository in windows batch file - the system cannot find the file specified

Question

How do I get a SVN revision number of a remote repository in a windows batch file ? I want to check for a condition when the user enters blank i have to get HEAD revision.

I'm using the following snippet to get the revision number. Although the for loop returns all the necessary information wrt remote SVN server location including the revision number. Still the batch file throws The system cannot find the file specified and the variable %SVN_VERSION% still remains empty.

In the below mentioned code, the %SVN_PATH% points to the remote server URL

set /p "SVN_VERSION=Please specify the SVN Revision number. For HEAD revision press Enter"
    if "%SVN_VERSION%" =="" (
    for /f "delims=: tokens=1,2" %%a in ('svn info %SVN_PATH%') do (
              if "%%a"=="Revision:" (
                set /a SVN_VERSION=%%b
            )
        )
    )

Thanks

As I mentioned in the comments, you can directly obtain revision with svnversion command .

@echo off
set /p "SVN_VERSION=Please specify the SVN Revision number. For HEAD revision press Enter"
if "%SVN_VERSION%"=="" (
    for /f %%a in ('svnversion') do set "SVN_VERSION=%%a"
)
exit /b 0

Edit

Here it is well explained how to use the command svnversion

Edit

According to your comments and trying to guess in your mind, the following command should work if you know the remote_url

@echo off

rem Edit remote_url
set /p "remote_url=Please specify the SVN repo url http://....." || goto:EOF

set /p "SVN_VERSION=Please specify the SVN Revision number. For HEAD revision press Enter"

if "%SVN_VERSION%"=="" (
    for /f "delims=: tokens=1,2" %%a in ('svn info %remote_url%') do (
        if "%%a"=="Revision" ( set SVN_VERSION=%%b )
    )
)
exit /b 0

Edit

This should also work since I have seen what should be the input

@echo off

set /p "SVN_VERSION=Please specify the SVN Revision number. For HEAD revision press Enter"

if "%SVN_VERSION%"=="" (
    for /f "tokens=1,2" %%a in ('svn info %SVN_PATH% ^|findstr /ic:"Revision"') do set SVN_VERSION=%%b
)
exit /b 0

Explanation:
Your mistake was with delims=: since : is not part of the tokens the comparison came wrong. Also, the default delims is space, so don't need to specify a delims here since the line are splited in two parts.
