Simple directory list command with filename wildcard support (Python)

2016-12-02T20:52:56-08:00

Python recipe 580724 by Vasudev Ram (commandline, directory, file, filesystem, python, utilities).

This recipe shows a simple directory listing program. It can accept multiple command-line arguments specifying filenames. These filenames can include wildcard characters like * (asterisk) and ? (question mark), as is common in OS command shells like bash (Unix) and CMD (Windows). Tested on Windows but should work on Unix too, since it uses no OS-specific functions, or rather, it does use them, but that happens under the hood, within the libraries used.

Create a zip bomb, for testing (Python)

2016-06-07T13:11:50-07:00

Python recipe 580676 by Simon Harrison .

This creates a zip bomb with a programmable recursion depth. It's useful when you want to create a very deep zip archive for testing decompression software, virus scanners and so on. Recursion depth is limited by Python itself, so very high values are probably not going to work. The algorithm could be re-structured to avoid recursion, but I've never needed a nesting depth of more than 900!

Each zip file will get the name stack<n>.zip where <n> is the number of zip files inside each layer. The data file at the core is called needle.txt.

embedded ssl (Perl)

2015-07-17T01:39:05-07:00

Perl recipe 579083 by Roger Mbiama Assogo (root).

"This module is a true drop-in replacement for IO::Socket::INET that \ uses SSL to encrypt data before it is transferred to a remote server \ or client. IO::Socket::SSL supports all the extra features that one \ needs to write a full-featured SSL client or server application: \ multiple SSL contexts, cipher selection, certificate verification, and \ SSL version selection. As an extra bonus, it works perfectly with \ mod_perl."

Stopwatch in 26 lines (Tcl)

2014-09-05T13:33:13-07:00

Tcl recipe 578927 by Mike Manilone (gui, time).

This stopwatch works on Tcl/Tk 8.5 and higher. It makes use of the [clock] command and reduced the amount of code by -textvariable. A simple one, indeed. Nevertheless, it is still easy-to-read and easy-to-understand and it does show the power that Tcl has.

Batch recipe 578516 by Barry Walker (audio, generator, sound, sound_exchange, sox, windows).

32 bit Windows to Windows 7...

This batch file generates a 65536 byte binary file to give 8 seconds of pure sinewave at the earphone/speaker output(s)...

It uses ONLY a default Windows 32 bit installation, to Windows 7, except for the installation of SOX...

Obtain SOX from here:-

http://sox.sourceforge.net/

Notepad was the _main_ editor... ;o)

Hopefully the code section does NOT corrupt the binary part which is 8 bytes in size. If it does then let me know on here and I will post a pointer from where to grab it...

Enjoy...
