All in one solution for all the scripts of vim from vim.org

For quite sometime now, I was looking for some console based program which would help me get the scripts from vim.org. A simple solution would have been to do a wget for the scripts. But since there are so many scripts coming up daily and with a need to search based on script ID and name of the script, I thought better to write a script that can do all of those things. Now, what was required was that the script should be either able to download this or add to the GLVS script. Also note that, I had done something similar in the past here. There are some additions in the below script. You can download a copy of the script get_vim_scripts. Or you can copy the script from below:

configuration for afraid-dyndns on Fedora and other similar distro.

First install afraid-dyndns with the command:

  <td>
    <div class="text codecolorer">
      sudo yum install afraid-dyndns
    </div>
  </td>
</tr>

Now open the configuration file /etc/afraid-dyndns.cfg and we need to change the following:

Notify = root@localhost # leave empty to suppress notifications
CacheFile = /var/cache/afraid-dyndns/IP
AccountHash =

For the Account hash, head over to http://freedns.afraid.org/api/ login and then click one of the XML or the ASCII links there. Once the page has loaded, look at the URL which is of form:

print every nth line

Some time back I was working with lot of data and wanted to analyze only the every 10 line sometimes and sometimes every 20th line. I had to keep doing these changes in vim or otherwise so finally I wrote a program to do this for me. If you need such a program then here it is:

  <td>
    <div class="text codecolorer">
      #!/bin/bash -<br /> #===============================================================================<br /> #<br /> #          FILE:  print_nth_line.sh<br /> #<br /> #         USAGE:  ./print_nth_line.sh<br /> #<br /> #   DESCRIPTION:  Print every nth line<br /> #<br /> #       OPTIONS:  ---<br /> #  REQUIREMENTS:  ---<br /> #          BUGS:  ---<br /> #         NOTES:  ---<br /> #        AUTHOR:   (),<br /> #       COMPANY:<br /> #       VERSION:  1.0<br /> #       CREATED:  12/08/2010 05:36:53 PM IST<br /> #      REVISION:  ---<br /> #===============================================================================<br /> <br /> if [ x"$1" == "x" ]<br /> then<br /> echo "Please provide the line numbers to print .. .ex 3 will print 3,6,9"<br /> exit -1;<br /> fi<br /> if [ x"$2" == "x" ]<br /> then<br /> echo "Please provide the filename"<br /> exit -2;<br /> fi<br /> awk 'temp++ { if ( temp % '$1' == 0) print $1};' $2
    </div>
  </td>

/bash debugger

9.2. A bash Debugger

In this section we’ll develop a very basic debugger for bash.[10] Most debuggers have numerous sophisticated features that help a programmer in dissecting a program, but just about all of them include the ability to step through a running program, stop it at selected places, and examine the values of variables. These simple features are what we will concentrate on providing in our debugger. Specifically, we’ll provide the ability to:

Gnome Tips

Add/Edit GDM Sessions

Each session is a *.desktop file located at /usr/share/xsessions.

GDM appearance

You can change background image, gtk/icon theme by hands (as described at Gnome_2.28_Changes#Configuring_gdm_2.28), or you can use gdm2setup from the AUR.

Tweaking

If your gnome applications seem sluggish and gnome hangs at start-up after killing the previous session, it’s likely you haven’t set your /etc/hosts file correctly and your /etc/hosts file includes:

127.0.0.1       localhost.localdomain     localhost      YOURHOSTNAME

Then run “/bin/hostname YOURHOSTNAME” and “/sbin/ifconfig lo up” as root.

install all solaris software from http

If you are behind a firewall and install some software like top or wget then you can not use sunfreeware, and why because ftp is blocked. Now that is not the case any more, you can go the http mirror site of sunfreeware and here is the link for the same

http://ftp.sunfreeware.com/ftp/pub/freeware/i386/5.10/

Note: you just need to change the words in bold for sparc or i386 and version of the solaris.

Using ssmtp to send mail using gmail.

First install the package ssmtp using the command:

  <td>
    <div class="text codecolorer">
      sudo yum install ssmtp
    </div>
  </td>
</tr>

Open the configuration file for ssmtp as root user:

  <td>
    <div class="text codecolorer">
      vim /etc/ssmtp/ssmtp.conf
    </div>
  </td>
</tr>

Make the following changes to the configuration file:

root=**username**@gmail.com
mailhub=smtp.gmail.com:587
hostname=**username**@gmail.com
UseSTARTTLS=YES
AuthUser=username
AuthPass=password
FromLineOverride=yes

In order to make the default (root) “from” field be the server name,
edit the /etc/ssmtp/revaliases file as root user :
