If you are running OpenSSL as a regular user, or cannot perform “RunAs Administrator”, and you get this error message:
unable to write 'random state'
then make sure you have set your environment variables correctly before running OpenSSL:
RANDFILE=%LOCALAPPDATA%\.rnd
A full batch file front-end for OpenSSL.exe is this one:

Wow: I feel like having lived under a stone for 8 years, as RosettaCode has been alive since it was founded in 2007 by Mike Mol.
The idea is that you solve a task and learn from that, or learn by seeing how others have solved tasks or draft tasks.
So in a sense it is similar to the Rosetta stone: it has different languages phrasing the same tasks.
There are already a whole bunch of languages on RosettaCode (of which a few are in the categories below), and you can even suggest or add your own languages.
When you want to solve tasks, be sure to look at the list unimplemented tasks by language that leads to automatic reports by language (for instance two of the languages I use most often: C# and Delphi).
I’m sure there are lots of programming chrestomathy sites, even beyond the ones, and it feels very similar to programming kata sites.

Two interesting links today about Delphi and Batch files.

I never realized you could overwrite the CD pseudo environment variable. If you do, the automatic value of the pseudo variable will not be udpated any more:
You have at some point set the CD variable explicitly. If you do this it will no longer automatically reflect the current working directory. To undo this, set it to empty:
set CD=
Thanks Jonathan and … for explaining this in both your answers.
Thanks to another answer by Endoro I now also know of the %=C:% pseudo variable (you have one per drive letter) that indicate the current directory per drive letter.

I just found this [Wayback] great answer (which by now regrettably is deleted; the previous Wayback link still has it) by [Wayback] Јοеу a.k.a. Johannes Rössel on [Wayback] What encoding/code page is cmd.exe using.
The whole answer is worth reading, so I won’t quote only some bits.
Edit 20210609: the answer now has been replaced by an even more detailed answer [Wayback] by [Wayback] andrewdotn. Also recommended reading. The summary of the new answer is this:
The moral of the story?
typecan print UTF-16LE files with a BOM regardless of your current codepage- Win32 programs can be programmed to output Unicode to the console, using
WriteConsoleW.- Other programs which set the codepage and adjust their output encoding accordingly can print Unicode on the console regardless of what the codepage was when the program started
- For everything else you will have to mess around with
chcp, and will probably still get weird output.

Small batch file that shows you the files on the path. It is a simple version that does not take into account built-in commands of cmd.exe, DOSKEY macros or PATHEXT environment variable: it just matches a name of an executable. Rob van der Woude has a complete which.bat (text version here) that does take into account all of the above. This is the poor man’s version:
@echo off for %%f in (%1) do @echo. %%~$PATH:f goto :eof
It uses this little trick from the FOR command:
| %~$PATH:I | Searches the directories listed in the PATH environment variable and expands %I to the fully qualified name of the first one found. If the environment variable name is not defined or the file is not found by the search, this modifier expands to the empty string. |

For DOS programs, date and time stamps were used to mark versions of files. For instance, Turbo Pascal 6.0, had a 06:00 time stamp on every file.
You can still do this in Windows, but need to watch for a couple of things:
There are various ways to do it. Besides a graphical Attribute Changer at www.petges.lu (thanks User Randolf Richardson), these are console approaches via How can I change the timestamp on a file?:

Many people confuse a shell with a console.
They are distinct: the shell executes commands, and the console hooks up video and keyboard to them.
Some products (like Take Command Console, of which Noah Coad is a huge fan) combine the two.
Some shells you can use for Windows: Read the rest of this entry »

I’ve a long history in DOS/Windows 9x COMMAND.COM and Windows cmd.exe shell programming.
The switch to PowerShell is steep, but for me it is worth it: it has so much more functionality than cmd.exe, and taps right into the .NET ECO system.
If you look for something intermediate, you might want to consider TCC. Formerly TCC was known as 4NT, which has its roots in 4DOS (I totally loved 4DOS back when cmd wasn’t there yet).

Since Visual Studio is always in a 32-bit directory, I needed the SetProgramFilesX86 batch file from
Windows batch file to set ProgramFilesX86 directory for 32-bit program files on x86 and x64 systems.
Here is a small batch file to list workspaces by any user for the current directory (assuming that directory is mapped to a workspace):
call "%~dp0SetProgramFilesX86.bat" :: assume Visual Studio 2005: ::"%ProgramFilesX86%\Microsoft Visual Studio 8\Common7\IDE\tf" workspaces /owner:* /computer:* :: assume Visual Studio 2010: "%ProgramFilesX86%\Microsoft Visual Studio 10.0\Common7\IDE\tf" workspaces /owner:* /computer:*
It uses TF, and assumes default locations for various Visual Studio versions based on the internal version number.
A generic TF batch file that finds the TF is this one:
call "%~dp0SetProgramFilesX86.bat" :: assume Visual Studio 2005: ::"%ProgramFilesX86%\Microsoft Visual Studio 8\Common7\IDE\tf" %* :: assume Visual Studio 2010: "%ProgramFilesX86%\Microsoft Visual Studio 10.0\Common7\IDE\tf" %*
