Question

I have a script who creates new tags in a SVN, and add some files. I want to automate this task so I would like to find some way to do automatically the incrementation for the tags name, from 1.0 to X.0.

I thought about a conf file who would contains “1.0” as a first version number and who would be overwrite at each call to the script. But not sure I can get the “1.0” value from the file and then do an incrementation on it in my script.

Any help would be really appreciate.

Thanks in advance

Don’t create a seed configuration file. Instead, let the batch script default to 1.0 if file does not exist.

@echo off
setlocal
set "conf=version.conf"
if not exist "%conf%" (set version=1.0) else (
  for /f "usebackq delims=." %%N in ("%conf%") do set /a version=%%N+1
)
set "version=%version%.0"
(echo %version%)>"%conf%"

I’m assuming you will never run this process multiple times in parallel – it can fail if you do run in parallel. Modifications can be made to lock the conf file so you can run in parallel if need be. See the accepted answer to how to check in command line if given file or directory is locked, that it is used by a process? for more info.
