Total Commander

multiline searches don't work in TC period.
The file I tested with is 912 bytes, and TC refuses to find a multi-line regex. Whereas a dinky 132kb application grep.exe does so happily.

AFAIK the whole file doesn't need to be in memory to search it for multi-line, you flag partial matches and continue scanning the file until the partial match becomes a complete match or no match.

Because Total Commander does a line by line search and "Alpha" and "Bravo" may be on different lines.

Fortunately this was not a problem in my case, but I have UTF8 encoded files, so regex could not be used anyway. I tried to manually translate my keywords into 1251 ANSI codepage and then apply for search, but it doesn`t work. Aside of this it takes about 6 hours for a 100 MB directory with 100% load on one of two processor cores.

Try searching for the binary (utf8) codes of your keywords and remove the leading and trailing ".*" because that is very inefficient.

A regex search of:
\x41\x6c\x70\x68\x61.*\x42\x72\x61\x76\x6F|\x42\x72\x61\x76\x6F.*\x41\x6c\x70\x68\x61

is the same as a regex search of:
Alpha.*Bravo|Bravo.*Alpha

Thank you for the tip, I will try it tomorrow.

But I still think it is not so handy to make such a regexps for the simpliest search. It must be improved.

Moderators, could you please move this thread to suggestions?

2Hacker, thanks.

Your tip speeds up the search a lot, thank you.

But as I can see, it is more efficient to unpack my files manually and to use the regular search twice then. Very uncomfortable

AFAICT Grep, et al from UnxUtils aren't any help in these particular cases either -- unless there is some setting I am missing. Everytime I try and use a linux-based tool with anything remotely close to unicode or utf-8 or the like, they fail miserably (even the ones specifically compiled for windows).

On slashdot there's a common meme about When will it be the "year of the linux desktop". To me, that sure as hell isn't gonna happen until linux starts supporting more than basic ansi.
