AWK
by Ben Norcutt 06 Jul '01

06 Jul '01

Hi, After a few days head scratching I thought I'd ask this one. Basically what I want to do is this: I have 2 files one containing urls called url with each url on a new line and another containing words called keywords with each keyword on a new line I want to search the url file for each of the keywords in the keyword file and output any matches to the file output I can do this for individual keywords using awk '/word1/||/word2/||/word3/' url > output But I need a way to do it for a load of keywords. Anyone got any thoughts? Cheers, Ben

Encrypting disks...
by Andrew J Glover 06 Jul '01

06 Jul '01

Hi, On IRC Monday I asked a brief question about the kerneli patches, and he (? scoobz) said they had no problems... question is, before I settle on that, has anyone else had experience with that, or any other linux encryption fs? Thankyou! Andrew

LINUX EXPO BIRMINGHAM
by David Freeman 05 Jul '01

05 Jul '01

Neill (I think) mentioned taking a tent upto Linux expo in september, I quite like the idea, I need a holiday, I already have that week booked as leave, so, who else is interested in a) Coming to the expo for the day? b) Staying up there and having a bloody good laugh? Perhaps we could go as the ALUG, maybe with the alug T-shirts which we discussed recently on the list and at the meets? And I wont come back without a 3ft TUX!

perl -e 'print map chop, sort split shift, reverse shift ' 'j_' 'e._jP;_jr/_je=3D_jk{_jn*_j &_j :_j @_jr}_ja)_js$_j ~_jh]_jt,_jo+_jJ"_jr>_ju#_jt%_jl?_ja^_jc`_jh-_je|' -rjk- I actually executed this (more fool me, not knowing what the hell it did). What I find very interesting is that it printed: Just another Prl ehacker The problem is that 'quoted printable' thing again; an '=' got converted to '=3D'. Upon removing the 3D, it prints: Just another Perl hacker How's that for a resilient language! (my guess is it turned up in a regex and the regex just didn't match, but I can't be bothered to read that code). Incidentally, my $.02 on the write-only language bit; this is how I'd write the above, and I think many people would agree this bit o' Perl is a clear, well structured and elegant solution to the problem: perl -e 'print "Just another Perl hacker\n"' Show me a language clearer than that...

Help with Mulinux, please
by Ruleng＠aol.com 05 Jul '01

05 Jul '01

Hello, I first want to thank those members of alug who are already trying to help me with my problems with Mulinux. I was interested to find that markj@cloa has had the same kind of problem that I am having. However, I think that the cause is something that I do not understand and am doing wrong. I do not think that the cause is the fact that the distribution is not being updated as he suggests. Going to the Mulinux homesite and looking at /mulinux/mu/current one finds that there have been eight versions of the kernel this year, 2001, from mulinux-11r6 last modified 18 Jan 2001 to mulinux-12r0 on 14 Jun 2001. Similarly, of the eleven addons,the five earliest were last modified on 23 Dec 2000, and the three latest on 14 Jun 2001. I suspect that some of those writing about Linux, especially if English is not their native language, for DOS users do not appreciate the "ignorance" of the latter on things Linux. Some writers to the Mulinux homesite have asked how one can make a 1.722 Mb floppy. The answer, as I remember, was not satisfactory. Best wishes, Norman Rule

Hi John: I'm always pretty hesitant about offering advice as i am more or less usually completely wrong, but if you want to try a few things whilst waiting for an expert to comment on this, i would have said to take a look at your /etc/X11/XF86Config file - "pointers" section, or rerun XF86Config from a cli.

First suggestion: don't expect it to work in the same way as Windows. You have many many more options of what software to use, some of which will effect the basic appearance and behaviour of the system. So, what Linux would people suggest? Is Mandrake still the general recommendation for people starting off? Or is Debian now ready for the beginner, either on its own or via Progeny? -- MJR

Linux Expo, Wednesday, Where and when are we meeting?

There was apparently an agreement reached on IRC tonight as to a place and time within the exhibition where alug members would meet to compare freebies etc. M J Ray asked if someone would post the details to the alug-announce mailing list, but I think by then anyone who had been party to the discussion has left IRC. If you were party to the discussion and rememeber what time and place was agreed could you please post a message to the alug-announce mailing list with the place and time concerned. Steve.
