[Ilugc] extract sentences from a xml file in bash
Friends. I have a text file to extract content from. The format is like below title = Mr name = shrini phone = some number email = email address address = home address city = chennai state = tamilnadu country = india The same block continues as multiple times in the file, but in records are in different order. I want to extract any two lines from the entire file. for example, I want to get the pair of name, phone or name, city or name,email address or name, state etc How can we use the bash utilities to achieve this? Thanks. -- Regards, T.Shrinivasan My Life with GNU/Linux : http://goinggnu.wordpress.com Free/Open Source Jobs : http://fossjobs.in Get CollabNet Subversion Edge : http://www.collab.net/svnedge ___ ILUGC Mailing List: http://www.ae.iitm.ac.in/mailman/listinfo/ilugc
[Ilugc] Please suggest Linux server
Hi, We have a plan to replace windows 2003 server by CentOS. This CentOS will authenticate all other windows desktops using Samba PDC. Total users are 30. As of now we have thinclients with Windows 2003 server. Before adopted with this setup, we had checked using one thinclient. While testing, we felt that it was ok. After place 15 thinclients by connecting with IBM X3400 server , we started to realize slow issue. For example, if one user opens a pdf file, it takes time. Due to this slow issue,we are planning to replace all these thinclients by desktops. Then these desktops will be installed by Windows OS. Then these windows desktops will be authenticated by Samba PDC. Samba PDC configured in a desktop configurationCeleron 1.8 GHZ,512 MB RAM). This system will act as gateway and squid proxy also for our network.IBM X3400 is 4 years old. So we are not able to decide to continue with this server for further operations. Please suggest configuration or server model for Samba PDC to authenticate 30 users. Thanks for your time. ___ ILUGC Mailing List: http://www.ae.iitm.ac.in/mailman/listinfo/ilugc

Is there a fixed set of 'fields' per record? If yes, the solution could be
a lot simpler and possibly done using awk or a combination of shell tools.
If not, try this perl "one liner":
sample input file:
$ cat file
name=ravi
phone=101
email=a@b.c
phone=011
email=c@b.a
name=vira
email=a...@a.com
name=crap
email=s...@s.com
name=supercrap
The solution (which I've formatted here for ease of readability):
$ cat file | perl -MYAML -ni -e '
BEGIN {
@db = ();
$rec = {};
%keycounter = ();
$next_rec_at = 1;
}
chomp;
($k, $v) = $_ =~ m/^(.*?)\s*=\s*(.*)/gms;
$kcount = ( defined $keycounter{$k} ? $keycounter{$k} : 0 );
if ($kcount >= $next_rec_at) {
push(@db, $rec);
$rec = {};
$new_rec_at++;
}
$rec->{$k} = $v;
$keycounter{$k}++;
END {
push(@db, $rec);
print YAML::Dump(\@db); # ... or do your report generation here
}'
output:
- email: a@b.c
name: ravi
phone: 101
- email: c@b.a
name: vira
phone: 011
- email: a...@a.com
name: crap
- email: s...@s.com
name: supercrap
cheers,

You will instead see unified disk(s). * unless you also have some kind of a specialized software (such as HP ACU CLI) using which you can 'talk' to the raid controller to query various things from it (such as the list of drives installed, their status, etc.,).

[Ilugc] Problem adding widgets to GNOME panel
Hello All, I run a machine with CentOS 5.5, GNOME version 2.16.1. When I log in, or when I try to add new widgets like Clock, or WindowList to my GNOME panel (by doing 'Add to Panel') . I get the below error message all over my screen, The panel encountered a problem while loading "OAFIID:GNOME_WindowMenuApplet" The panel encountered a problem while loading "OAFIID:GNOME_WindowListApplet". The panel encountered a problem while loading "OAFIID:GNOME_WindowMenuApplet" Each of the message in separate windows. Widgets like WindowListApplet are critical to me, since without it, any minimized window just disappears and I have no way of retrieving that window. I googled around and tried the following, $ pkill gnome-panel $ gnome-panel & deleted ~/.gconf/apps/ and allowed the panel to build itself from scratch when I logged back in. but nothing seems to work. Please tell me your suggestions. Note : Crossposted in linuxquestions.org Regards Sugantha ___ ILUGC Mailing List: http://www.ae.iitm.ac.in/mailman/listinfo/ilugc

[Ilugc] MS Cloud operations in TN
Hi ILUGC, I guess it is time for ILUGC to start another campaign against the TN govt. When the neighboring state of Kerala is doing so much with Open Source, why is TN govt. falling into a trap with MS? (Refer yesterday's hindu: http://www.thehindu.com/news/states/tamil-nadu/article2967682.ece) IMO, the last thing that we would want is for our state to fall into a vendor lock-in with MS. I guess it would take a fraction of the cost if we develop TN. govt. its own private cloud. Anyway, I think we first need to tell TN govt. that what they are doing is wrong. Any ideas on how to go about with this? With Regards, ~~Kumaran R ___ ILUGC Mailing List: http://www.ae.iitm.ac.in/mailman/listinfo/ilugc

Re: [Ilugc] MS Cloud operations in TN
The normal way would be to approach ELCOT with the proposal.but having said that ..there is a lot of political and monetory influence is connected with government in these activities ..but still its no harm in taking this to ELCOT ...people are still educated there will have ears to listen .taking it from there to the government to amend depends ministers who still thinks cloud computing as computer to use at the time of rainy season as we use umbrellasuch is the knowledge of people in power.still I would suggest it as worth a try .

Re: [Ilugc] Please suggest Linux server
I don't know much about the server hardware requirements. But IMO, you can have the Desktops in this configuration: CPU+Board: Intel Atom Desktop Kit - Rs. 3400 RAM - Hynix LapTop RAM 1 GB - Rs. 475 No Hard-Disk Some Case ~ Rs.1000 We had a similar issue in my school, and we had to dispose of around 15 thin-clients. Now, we're using the above configuration (but with HDDs). You can use PXE and reduce your cost. With Regards, ~~Kumaran R ___ ILUGC Mailing List: http://www.ae.iitm.ac.in/mailman/listinfo/ilugc
