comment Merge and export OCRed text into and from a pdf file
No, I wouldn't need that. I would have the text searchable in SVG, with detected font, and everything is positioned with SVG instructions. I don't know but I find that very interesting, I made several XKCD comics in searchable SVGs with Sans Serif Font, by using tesseract, hunspell, opencv and svgwrite and potrace (as Python modules) ;)

comment Merge and export OCRed text into and from a pdf file
Well HOCR, is XHTML so it is XML, and there are tools many ways for producing PDF out of it, but that's involved, and other formats like EPUB or else... If I would have to do something like (assuming making PDF image for printing) then I'd use Python and convert HOCR to SVG. From SVG I'll have much more options, but that's just me...

I just did that and thought to report, but there you are :) Patch from comment 5 works great!

comment How to install .tar.bz and .tar.bz2 packages?
Those are archives. You need to unpack them and see for instructions inside. Usually it's ./configure, make, make install, but I'm sure someone will provide better answer to you, with links where you can learn this very basic things before you actually try to build anything

comment Creating recursively sorted RAR archive
Thanks Eli for your answer, but unfortunately none of provided examples stores file sorted here. I'm also on Ubuntu. find * | sort lists files sorted but find * | sort | xargs rar ... stores files in unsorted order for some reason. I tried also -n@ (with additional sort command) which works fine as in your snippets, but again it does not store sorted files. I could provide screenshot from terminal if anyone requests it. So for me, snippet that works is the last update to my question: for d in */ ; do rar a -r archive.rar $d*.txt ; done which loops over folders and is acceptable to me

Yeah, I started with gzipped tar and then wanted to update archive... rest is history, w/o even mentioning all handy rar options

comment Creating recursively sorted RAR archive
Yes, I do, as I pipe uncompressed output to stdout with rar p. BTW unrar -v switch you mention, does not do anything here - did you test it?

comment diff - output line-numbers
Just great! Thanks :) I tried to guess from help listing, but w/o success, and thought I misread it. Then I made what I wanted with Python (difflib module with indexed files per line in list object) only that I couldn't use diff <(pipe buffer1) <(pipe buffer2) with Python, like I planed with diff. Now you saved me :)

comment make grep output without trailing newline
ah tr... interesting, works both on LF and CRLF files. I would think \010\013 for some reason, and also \f\r works correctly. About the result: I don't actually put the output in variable but as variable enclosed in $() in pattern for grep match - some pipe | grep -o " $(...) ". Thanks for comments

comment make grep output without trailing newline
Thanks Chris for your effort and correct answer. I still haven't got to awk, as to know the syntax, what I should, should not... but your explanation makes it simple in this case. Cheers

comment make grep output without trailing newline
OK, this time it does it good - output last word in a line if that line satisfies some pattern condition - don't know, maybe it's clear to me because I have this problem, and then hard to explain as non-native english speaker. Anyhow, I'll wait a bit more if someone addresses this with grep/sed solution instead awk (which I don't understand), and if not I'll use it. Thanks

:) Now it doesn't look elegant any more and it is still no good

Thanks, it looks elegant but unfortunately CRLF is still inside X

comment Opensuse 11.4 very slow on 8 GB RAM i5 processor
Is Eclipse your only performance problem? I had similar issue (with PyDev) when I found out that it indexes myriad modules in system's Python library path. Then I removed this folders in preferences. So it doesn't matter you have high-end machine if it needs to access HD to infinity

comment How to check if pipe is empty
OK, thanks. I'll use temp file. I found in the meantime there is ifne command from moreutils deb package that does exactly that, but it's not on my system.
