Batch file: file mask

I couldn't find details about how to use file mask in a batch file. My requirement,

forfiles -p "C:\what\ever" -s -m *.log  -c "cmd /c somecommmand"

instead of selecting all the log files (*.log), how to select all the log files which has an integer suffix at the end. Eg, Among the following files,

test.log, test1.log, test2.log, test3.log..

I need a file mask to select all except test.log

I tried test*.log, but that slects test.log as well. It is preferrable to not include the file name part (test). something like, *<0-9d>.log .

thanks.

To match file names against a regular expression in a batch file you can use the following for loop as a template:

for /F "delims=" %%I in ('"dir /B /S | findstr /E "\\test[0-9][0-9]*\.log""') do (
    echo %%I
)

This simply prints the full paths of all files in the current directory and its sub directories, whose name matches test1.log, test2.log, test3.log, ...

The dir command produces a listing of the directory tree from the current directory. Each line contains a full path. The listing is piped through the findstr command, which matches the full paths against the given regular expression. On each iteration the for variable %%I contains the full path of a file that has matched the regular expression.

You could try the following, which I personally think is terrible, but it may just be what you need:

FOR %i IN (1 2 3 4 5 6 7 8 9 10 11 12 13 ...) DO IF EXIST test%i.log (somecommand)

If the suffix is really any integer number in a potentially very large range, this won't work — unless you nest several FOR loops, where each takes care of only one digit, and you change the IF EXIST test%i.log to something like IF EXIST test%a%b%c%d.log (for four digits).

Also, there's no need to execute somecommand in a separate shell (CMD /C), unless of course that is in fact what you need to do.

As test?.log and even test??.log will find test.log, too, the only thing to get what you want would be some type of workaround, for example:

if exist test.log ren test.log test.tmp
REM Do your stuff here, you can now use test*.log
if exist text.tmp ren test.tmp test.log

I don't know if this unexpected behaviour of ? (not meaning exactly one character, but at most one character) is something Windows specific or was like this since DOS, but it can be very annoying.
