This line below exactly:

‘Hurd’ stands for ‘Hird of Unix-Replacing Daemons’. And, then, ‘Hird’ stands for ‘Hurd of Interfaces Representing Depth’.

Haha GNU has very nice recursive stuff always, I wonder how much thinking it took them to arrive at that! My laughter stack has already overflowed. ;)

Shorten the apt-get install!

one comment

sudo apt-get install [name]

Thats probably one of the most used commands on your Ubuntu box. Hate writing such long lines for while installing a package as quick as possible? This guide should help you reducing the length of that command to just, well, 1 character!

Like this example:

user@domain:~$ i john
Reading package lists... Done
Building dependency tree
Reading state information... Done
The following NEW packages will be installed:
john
(. . .)

Notice the one-letter i in the above? I created i to stand for apt-get install.

Unix/Linux have something fantastic in them called alias. The command alias is used to create shorter and quicker keywords to another command which could be very long with all its parameters. So lets move on to making a simple alias for apt-get.

Basically our command is:

alias i="sudo apt-get install"

But just giving that would not last anymore once your terminal is closed. To make it permanent we have to do the following in the Terminal:

echo alias i=\"sudo apt-get install\" > ~/.bash_aliases

Now give this command:

gedit ~/.bashrc

A text editor should open with some content in it. Now scroll a bit until you find the following lines: (Should be around 50~ lines from beginning)

#if [ -f ~/.bash_aliases ]; then
#. ~/.bash_aliases
#fi

Now remove those 3 #’s (hash comment symbols) from each of the lines so that they look like this:

if [ -f ~/.bash_aliases ]; then
. ~/.bash_aliases
fi

Save and close the editor. Restart your Terminal and voila, you can now do the i method as shown earlier! :D

Example:

user@domain:~$ i gnome-bluetooth
[sudo] password for user:
Reading package lists... Done
Building dependency tree
Reading state information... Done
gnome-bluetooth is already the newest version.
