I know, that p_r_colors=copy.deepcopy(p_a_colors) for i in range(len(p_rem)): p_r_colors= np

In the what's next section, I wrote about what I thought would be a good upgrade to the batch file. My question is: is it possible to create a batch file like I did in the post, but capable of optimizing multiple images at once? Drag and drop multiple .png files on it? (and have the output be something like new.png, new(1).png, new(2).png, etc... 回答1: Yes, of course this is possible. When dragging multiple files on a batch file you get

I.e. I'd like to having leading zeros for values lower than 10. 回答1: There's a two-stage process you can use: REM initial setup SET X = 5 REM pad with your desired width - 1 leading zeroes SET PADDED = 0 % X % REM slice off any zeroes you don 't need -- BEWARE, this can truncate the value REM the 2 at the end is the number of desired digits SET PADDED=%PADDED:~-2% Now

The regex ^[0-9][0-9]*$ worked fine for non-negative numbers but since I now support negative numbers as well I tried ^([1-9][0-9]*|0|-[1-9][0-9]*)$ for either positive or negative integers or zero. The regex works fine theoretically . I tested it in PowerShell and it matches what I want. However, with findstr /r /c:"^([1-9][0-9]*|0|-[1-9][0-9]*)$" it doesn't. While I know that findstr doesn't have
