I'm trying to get the revision number from a svn update command output. In the file tmpFile.txt I've got the string At revision 58998.

I've run the following command:

findstr /r "\<[0-9][0-9]*\>" "tmpFile.txt"

and I've got

At revision 58998.

Also, running with

findstr /r /o "\<[0-9][0-9]*\>" "tmpFile.txt"

I get

0:At revision 58998.

What's going on and how can I get only the number?

FINDSTR prints out the entire line that matches. It is not able to extract just the matching portion of the line.

You can use FOR /F to parse the output and get just the number.

for /f "tokens=3 delims=. " %%A in (
  'findstr /rc:"At revision [0-9][0-9]*\." "tmpFile.txt"'
) do echo %%A

What are the undocumented features and limitations of the Windows FINDSTR command?

The Windows FINDSTR command is horribly documented. There is very basic command line help available through FINDSTR /?, or HELP FINDSTR, but it is woefully inadequate. There is a wee bit more documentation online at https://docs.microsoft.com/en-us/windows-server/…
