General :: Making OS Match Hardware?
Jun 20, 2010
I have recently installed ubuntu 10.04 on my five year old desktop. Unfortunately, the official linux driver for my ATI X1600 card doesn't seem to support this ubuntu. There's an open source driver running now, but 3D applications run much slower than originally under windows. (which I can't seem to install on my sata raid harddisk anymore)
It's even so slow that I can't use those 3D applications anymore. I came to the conclusion that my computer is just too old for such a modern system as ubuntu 10.04. So I started looking for another version of linux. I tried the Linux Distribution Chooser, it pointed me at OpenSUSE 11.2. But I don't know, this program still looks kind of new. Too new for my computer.
I think that my computer needs an older version of linux, so that all the hardware will work properly. So I'd like to know if there's an older version of ubuntu/linux that still supports my hardware.
My computer was assembled from the following parts:
- DVDI LiteOn 16x/48x IDE bulk
- RAM 512 MB DDR/400 PC3200 ValueSelect
- HDDI 200GB 7200 Maxtor 6B200M0 8MB/SATA
- MB MSI k8T Neo2-F Athlon 64/939/DDR
- CPU AMD Athlon 64 3200+ 2.0Ghz/so939 BOX
- X GRA Sapphire R9600XT TV/DVI 256MB L-re
Does anyone know any distributions that fit this hardware? Some older versions of ubuntu perhaps? Something that allows me to install drivers that make 3D applications run a t normal speed? If someone knows about a Distribution Chooser that takes hardware into account, I'd also like to know.

I have the following query:
Code:
$sql="SELECT table1.datetime, table1.user_id, table2.ip, FROM table1,table2 WHERE id='$id' AND (table1.id = table2.id AND table1.datetime = table2.datetime)";
In table2 the datetime fields are about 1 to 2 seconds off due to the source of the data, which I cannot change.
Is it possible via a query match table1.datetime & table2.datetime by HH:MM (ie. to the minute instead of to the second)?

Say I had a string like so
Let's say I only wanted to grab TAC and BDX the ones in the 2nd, 4th, and 6th spot.
Will grab the lines from the rest of the file assuming these are the only lines with capital letters at the very beginning of each line.
Will delete the first 'T'. What I want to do is learn how to just pick the even characters, T(T)A(A)C(C) & B(B)D(D)X(X).
Is there something like the {1} which can pick just the even or odd character matches?

I am using sed to process an ascii tcpdump file whereby each packet is processed into a line with the same number of columns and useful information is pulled out like the time, packet type, length, and also IP addresses, payload type and port numbers where appropriate. The time is already changed to seconds, followed by the protocol over ethernet, such as IP, IP6, ARP etc. and I can change anything it detects as IP, IP6 and ARP into some other string, pulling out necessary information depending on the protocol and payload.The beginning part of the search for IP starts with the sed search /([0-9][0-9]*.[0-9][0-9]*)[ ]IP[ ,] ... /, where time is in seconds and ellipses means more stuff, and likewise for IP6 and ARP.But how do I process the lines that are NOT IP, IP6 or ARP? (Specifically NOT /IP[ ,]/, /IP6[ ,]/ or /ARP[ ,]/.) So that I can format them into a string with the same number of columns.

I want to traverse a directory and get a list of files that contain a set of patterns. I assumed I could use grep for this, but I having trouble getting grep to only return files that match ALL patterns. Here's what I've come up with so far:
Code:
grep --recursive --file=searchpatterns.txt --files-with-matches somedirectory/*
However, this gives me a list of files that match ANY of the patterns in the searchpatterns.txt file. I want to match ALL of the patterns. I've looked through the man page, but can't find anything that allows me to change the "OR" to "AND" for multiple patterns.

I have some lines of text and I want to detect words that meet some criteria with sed.
E.g. The line "tetris cat dog test cactus stereotype"
I want to detect the word that contains two (2) ore more t letters. That mean the words tetris, test and stereotype.
The following regex doesn't do the job because it can;t distinguish words very well.
I thinks I have ti incorporate something like [^ ] in the regex but I wasn't successful...

I have to use sed with this problem, and sed is extremely complicated, they could probably teach a whole class on this entire function.
Here's an example to show what I need to do:
Code...
how would I say that every line before I reach the first match of "sweet" should be deleted so that the output will look like: Code...

I have been fighting with a sed statement trying to get it to remove everything in a string until the last match and have been failing badly. how to get this to work..
sed --> enterprises.9.9.171.1.5.2.1.1.5
returns 5
I want sed to strip everything out until the last period. The final digit can and will change. Some parts before the final period can change as well, since enterprises will sometimes also be represented as more numbers and periods.

I'm trying to write a script where I want to check if any of the parameters passed to a bash script match a string. The way I have it setup right now is if [ "$3" != "-disCopperBld" -a "$4" != "-disCopperBld" -a "$5" != "-disCopperBld" -a "$6" != "-disCopperBld"]but there might be a large number of parameters, so I was wondering if there is a better way to do this?EDIT:I tried this chunk of code out, and called the script with the option, -disableVenusBld, but it still prints out "Starting build". Am I doing something wrong?
while [ $# -ne 0 ]

I use the Actions feature of KDE's Klipper utility to run certain commands when I copy something into the clipboard that matches a particular regular expression. Unfortunately, I have to turn on Enable Clipboard Actions and select the command from a menu every time I copy something that I want to run the command on. I'd like to have that command run automatically instead.
You'd think this was possible, as there is an automatic checkbox in the action settings dialog box:
Unfortunately, that appears to do nothing. The documentation included with Klipper does not indicate what that checkbox is supposed to do.
Is it possible to configure Klipper to run a command automatically if the contents of the clipboard matches a regular expression? If not, is there another way to accomplish this?

I'm attempting to search through a rather large assortment of html files created in Word using 'save as html'. what I'm trying to do is find and delete these tags (they're causing browsers to display black diamonds with white question marks):
<span style='mso-spacerun:yes'> </span> Tags contain from 1 to 4 spaces between opening and closing. I get positive results from this:
grep <span style='mso-spacerun:yes'> filename.html but once I attempt to tell it to match any number of characters up until the next '>' symbol, it tells me I'm using an invalid regex: grep <span style='mso-spacerun:yes'>[^>]+> filename.html
I've been nose-deep in regex tutorials for the past day or so, and I'm still not understanding why this doesn't work. If I put the pattern (without backslashes) into a separate file and use `grep -f patternfile filename.html`, I get no error but no matches either. So far as I can figure, the above regex boils down to:
Match the string "<span style='mso-spacerun:yes'>", followed by any number of characters that are not a ">", followed by a ">". If someone could tell me where I'm going wrong with this,

I have a weird/stupid question. How do you know what command would start an application after installing it, if the synaptic package name doesn't match?
For example google chrome and lmsensors. The first appears as Chrome in Synaptic and the second as lmsensors, but to run them you have to type google-chrome for the first and sensors for the second in the console to start them.
When I did locate sensors or locate chrome/chromium, nothing came up in the search that would hint me that I need to run those commands. I had to rely on a google search and look for someone else's answer. Is there a better way, one that I can figure it out on my own?

I have following 2 files
File1
10.1.1.1
10.1.2.1
10.1.3.1
File2
10.1.3.1
10.1.2.1
10.1.1.1
Both are reverse of each other. Now, basically if you see, the contents are same, but in different order. Is there any easy way in which i can find out like which items dont match between 2 files, regardless of order. Lets say i add 10.1.4.1 to File1. Now the result of such comparison should be only '10.1.4.1'. Currently if i am comparing both files using diff, it gives me all the lines.

I've been tasked with setting up a RHEL FTP server to mirror one we currently have. From what I've read, I need to install and configure VSFTPD and then configure IPTables. From what I've been able to come up with, I need to follow the steps in this article to install and setup VSFTPD. Is this a good complete article to follow you think?Also, how do I copy the iptables config from that server to my new one? I think that iptables on our current server only allows certain IPs or blocks certain IPs (not sure which), so I need to have it do that on my new server as well

I have this..
RewriteRule ^(apes|ape)/(.*)$ $2?fh=$1 [L,QSA]
I only want to match the directories ape/ and apes/ but I think it is matching any directory that ends in "ape" or "apes" or maybe does it match any string containing those characters in any order? I am not great at regex, and have read alot, but still not sure if I understand this correctly.

I want to make an rpm which when installed as an update causes another rpm to be removed. I'm fairly sure this is possible because I have seen LibreOffice rpms install as updates replacing OpenOffice rpms in the process without any interaction being required. However I'm unable to figure out how to do it, even after having looked at the spec file for such a LibreOffice rpm.
I have package gstreamer-0_10-ffmpeg installed. I have another package called multimedia installed. I've built a new version of multimedia which includes the gstreamer ffmpeg plugin so I don't need the gstreamer-0_10-ffmpeg package installed any more. I've tried using Provides and Obsolete in the spec file of the new multimedia package. E.g.
Code:
Provides: gstreamer-0_10-ffmpeg
Obsoletes: gstreamer-0_10-ffmpeg <= 0.10.10
(I've tried it with and without version numbers.) Whatever I put in the spec file, when I try and install the new multimedia package as an update zypper says
Code:
$ zypper up -y multimedia
Loading repository data...
Reading installed packages...
Resolving package dependencies...
Problem: multimedia-1.1-1.i586 obsoletes gstreamer-0_10-ffmpeg <= 0.10.10 provided by gstreamer-0_10-ffmpeg-0.10.10-0.i686
Solution 1: replacement of gstreamer-0_10-ffmpeg-0.10.10-0.i686 with multimedia-1.1-1.i586
Solution 2: do not ask to install a solvable providing multimedia > 1.0-2
Selecting an option manually is no good, I need the update to happen without user interaction.
