Utility scripts

recode.py (See source code)

Filter script to transform a text file from one encoding into another using Pythons unicode capabilities

re_filter.py (See source code)

Applies a regular expression substition to the files on the command line. Has the advantage over using sed, that it is possible to replace the files directly. No need to redirect to a temporary file first.

uvscan_update.py (See source code)

A script that checks for signature file updates for the McAfee virus scanner (uvscan), downloads and installs them. No need to hassle with manual updating anymore!

ttfinst.sh

Scans a directory for TrueType fonts, extracts the names and can create a fonts.dir file for the X font server, a Fontmap file for Ghostscript and PostScript font sample pages. Uses a tool called ttf-gs described in an article in the german computer magzine  c't. The article was called "Die wahre Schrift, TrueType-Schriften für Linux" by Jürgen Schmidt and was published in the issue 25/99, page 242. You can download the tools from the c't website.

mkttfsamples.sh

A helper script for the ttfinst.sh script. Makes a PostScript font sample page for a TrueType font.

cpcdda.sh

Copies an audio CD (CDDA) on-the-fly using cdrdao and cdparanoia.

kdemenu2ice

This (not really) small Python script converts the  KDE menu definitions into a  IceWM menu file. I know, there are already a lot of similar programs but this one does it's job with some special care. Full documentation can be obtained by starting the script with the option --help. This version currently needs the module cmdline.py, which can be downloaded here.

!!!This tool is utterly outdated and is provided here for download only for informational purpose!!!

crack.py

A password cracker, written also in Python. The script tries to decode the encrypted passwords in a UNIX passwd or shadow file by comparing them to a wordlist file. It tries all words in lower/upper case, with the first letter capitalized and backwards. It unterstands either normal (encrypted with crypt(3)) passwords or also MD5 encrypted passwords. It needs the modules utillib and authlib.

This script was written primarily for practice, don't expect it to be fit for real usage. It is far too slow, especially with MD5 passwords!.

This script is now included as an example in the auth-modules package!

utillib.py / authlib.py

Python modules containing a few utility functions, I use in my Python programs. Most interesting is an implementation of MD5 password encryption as employed by  PAM.

The authlib.py module is now included in the auth-modules package!
