All Files Enabling Searching Localy *BSD FTP Indexes

ATTENTION
1.) This article describes how to search xBSD FTP index files with help of Rexx scripting language.
2.) {f|n|o}bsd_index.txt files are generated by one script: make_bsd_index_files.rexx (see picture of them in Midnight Commander window: left panel shows infobase files in ~/lnbsd/locate/lb directory , in right one is displayed a "factory" with "output" and "input" files, scripts are placed in ~/lnbsd/scripts directory).
3.) ~/lnbsd is our base directory for LearN@BSD Project. Introduction to the directory tree can be found on this page: Polish in NetBSD: Handy Dictionaries from Infobases
4.) Our "search engine" np_lb script is flexible. You can search one file or all three at once. You can look throu all text, or word placed at the beginning of line (see below chapter Usage Information).
5.) Results printed to terminal window contains ftp hyperlinks to *BSD repositories. You can copy it to the same window after wget command and next copy application name.:
$ wget ftp://..... application
and press Enter, to have the appy downloaded in current directory. Forget openning html/ftp pages in web browsers or typing ftp links!
Digression: I know about dependencies but most users after some time of using *BSD have the dependencies installed together with other applications.

{f|n|o}bsd_index.txt

Index files made by make_bsd_index_files.rexx.

make_bsd_index_files.rexx

Main REXX script which downloads "raw" index files from xBSD web/ftp sites (in html form), renamed them, and processes them to {f|n|o}bsd_index.txt.

bsd_wget_index_files.sh

This script download the "raw" index files only. It is placed for those who want to get them by yourselves.

np_lb

Main search engine wrote as a bash/sh script. See some pictures further below on this page.

{f|n|o}_index.html

HTML files (e.g. nbsd_index.html) for processing. The genuine "raw" html files were renamed to process them more easily (coding script was more convenient, I could use arrays).

x.html.old or x.txt.old

Previous copies of HTML or TXT files.

Setting make_bsd_index_files.rexx

    homPath = "/home/lnbsd"
    bsdPath = homPath"/lnbsd/dict.db/dict.bsd/"

    PkgLen = 40               /* Application name span length */
                              /* displayed on screen          */
    

That's all. Nothing else has to be changed in the rexx script. PkgLen defines a gap between package (application) name and its description. Some file names e.g. within p5-* scope have widths of nearly 60 characters.
