RenByDate v2003.11a (a.k.a. QRen)

Finished up the first (re-)release of RenByDate which is a tool that will rename a file and allow you to insert things like the current year, or the day of the week into the filename. This is actually a re-write of QREN that I wrote back in 1991-1992 and uploaded to the CompuServe forums under the userID of 71750,3724 (and was also part of a larger package called QUTIL1). Back then, I charged $5/seat or $20/server for the package but now I'm re-releasing it under the BSD open-source license.

The old version of QREN was written for the MS-DOS platform (using the MIX C compiler) and used some MIX C specific call as well as not being able to handle longer filenames. During the re-write, I used MinGW and tried to re-structure the code to make for easy porting to other platforms.

Installation is as easy as copying the "renbydate.exe" file to a directory in your Windows PATH. None of the other files are required.

Using RenByDate is pretty simple: renbydate log.txt log_%Y%m%d_%H%M.txt will rename "log.txt" to "log_19921021_1455.txt" (if the date/time is currently Oct-21-1992 at 2:55pm). Or you can specify that it should use the timestamp of the file by putting the "-f" switch in. If you're using it inside of a batch file, you'll probably need to double-up the '%' signs (e.g. %%Y%%m%%d) because MS-DOS/Windows likes to interpret '%' signs differently then when you're using the command at the command prompt. As with the original version, it only handles single filenames and will choke on wildcards.
