shell-framework debian package

A week ago I was asked about debian package with shell-framework. I've prepared the package and now it can be installed as standard package. Instruction can be found here

библиотека shell-framework

Вместо введения
Я пишу скрипты на bash. Это скорее ближе к хобби, хотя иногда нужно и по работе. Конечно, не каждый день, но довольно часто и уже довольно давно. Бывают ситуации, когда либо не хочется пользоваться другими script-языками или когда у заказчика нет специалиста который сможет поддержать ваши скрипты в будущем, если они написаны, например, на perl - в общем, у меня бывало много случаев, когда моими скриптами должен был пользоваться не только я, но и еще кто-то и написаны они должны были быть на bash, а не на чем-то ином. Проанализировав требования к command line interface (CLI) программе, я систематизировал их и написал библиотеку, о которой и пойдет речь ниже.

blog was redesigned

Well, as you can see my blog was redesigned. New template approach impress me, but after all changes I've made some corrections.

One more note - sort, uniq and merging to the string

It is just one more note to myself. We have list of string - for example like this:

bg, cal, cat, cd, chmod, clear, cmp, cp, date, df, diff, du, echo, exit, fg, file, find, grep,
groups, gzip, head, history, id, info, jobs, kill, ln, locate, ls, man , mc, mkdir, more, mv, 
passwd, ps, pwd, rm, rmdir, scp, sed, set, sleep, slogin, sort, ssh, tail, tar, touch, uname,
vi, wc, which, whoami.

I need the same list without repeating of items and sorted.

protection from brute force on ssh

When I've tired from brute force attacks on my computer at 22 port I create simple protection.

Cell-phone file system access

Just short note about how we can explorer file system of cell phone (in my case it was Nokia 3120 classic). The main idea can be found at http://dev.zuckschwerdt.org/openobex/wiki/ObexFs.

mencoder ignore bitrate (1000 fps file)

Today I found my mencoder ignore bitrate option when I try to recode some file. After research I want to save here two links - http://lists.mplayerhq.hu/pipermail/mencoder-users/2006-April/003102.html and http://www.mplayerhq.hu/DOCS/HTML-single/en/MPlayer.html#id2910636 which show me to obligatory using "-ofps" option in case we have variable framerate in source file and fixed one in destination.

bash associative arrays(map, hash or how you them calls). part II

This is second part of story about associative arrays in bash. You will find first one here.

Well after very serious criticism about variable approach we have to look at second way. It is very simple - two arrays - keys and values.

bash associative arrays(map, hash or how you them calls). part I

There are a lot of programming languages where you can use associative arrays. Some times it has different name - map or hash for example, but the fact is bash had nothing like this before version 4.0 And if you use bash with version lesser then 4.0 you probably try to find some kind of solution.

mplayer32 on debian amd64

Well actually mplayer on 64bit debian is good enough. But today evening I could not play old movie from old CD. After investigating it was clear mplayer cannot find an audio codec:

...
Requested audio codec family [voxware] (afm=dshow) not available.
Enable it at compilation.
Cannot find codec for audio format 0x75.
Read DOCS/HTML/en/codecs.html!
Audio: no sound
...

But I was absolutely sure everything was nice in the past. The investigation of the issue showed the codec was accessible only for 32-bit version. Therefore I've found fast way to install mplayer32.
