If you have done a new installation of Ubuntu or Fedora, then yuou know you have to search all kind of blogs to find out what all to install. So, here is a easier way to do that. Just run this script, it will install some applications which are mostly a “MUST” for all the installations. And the list of applications that are installed are :

rpmconf – Tool to handle rpmsave and rpmnew files

2012-06-18 1 min read Bash Fedora

Install the utility:

sudo yum install rpmconf

Description:

Description : This tool search for .rpmnew, .rpmsave and .rpmorig files and ask you what to do

with them:

Keep current version, place back old version, watch the diff or merge.

And finally run the utility:

sudo rpmconf -a

and if there is a conflict or rpmsave or rpmnew file, then you will see something like this:

symlinks -delete all invalid soft links in Linux/Fedora

2012-06-12 1 min read Bash Fedora Linux

First of all, install symlinks if it is not installed :

sudo yum install symlinks

and here is the description:

Description : The symlinks utility performs maintenance on symbolic links.

Symlinks checks for symlink problems, including dangling symlinks

which point to nonexistent files. Symlinks can also automatically

convert absolute symlinks to relative symlinks.

Install the symlinks package if you need a program for maintaining

symlinks on your system.

Sometime back, we had looked at using colors in bash script and here is a way to create a array of all the colors.

count=0
for i in 40m 41m 42m 43m 44m 45m 46m 47m
do
    for l in 0 1
    do
        echo -n "l=$l "
        for k in 0 1
        do
            # echo -n "k=$k "
            for j in {30..37}
            do
                carr[$count]="\033[$k;$j;$l;$i"
                echo -ne "${carr[$count]}$count \033[00m"
                ((count++))
            done
        done
        echo
    done
    echo
done

You can add this script to any script of your choice and you have all the 256 colors available to you in the script without additional coding. Happy coding.

colors in bash scripts

2012-04-30 3 min read Bash Fedora Learning

I have been trying to understand the color codes for bash for a pretty long time, but somehow never got time to understand this clearly. So this time around when I was writing a script to analyze some logs. I thought I will give it a go and finally understood some part of this.

So, first we will start with this script. This is taken from here.
