How to install bootstrap in Ubuntu using terminal

Bootstrap is a free and open-source project available on Github developed to provide a front-end web framework. It keeps supported and developed by a large community of developers across the world. Bootstrap helps or provide a platform to web developers for creating highly responsive and interactive web applications.

It comprises HTML, CSS and Javascript together; HTML and CSS used to design graphical elements of the app such as buttons, navigation and rest of the interface while Java to make all the interactive elements work along for extension of the web app capabilities. If you are a beginner in web developing along with Linux operating system then these commands will help to install Bootstrap on Ubuntu via command terminal…

Install bootstrap in Ubuntu using terminal

Step 1: Open Terminal

Here we are using the Ubuntu 19.04, but the tutorial’s steps will be the same for other older versions such as Ubuntu 18.10/18.04-16.04-15.04…

To open the terminal either press CTRL+ALT+T buttons altogether or right click on the Ubuntu desktop on blank area anywhere and select the Open Terminal option.

Here are multiple ways to install bootstrap on Ubuntu, choose one which suits your requirements…

Download Bootstrap directly using git to get the compiled CSS and JavaScript

You can directly download the Bootstrap project from their official website using wget command or clone it using git. The downloaded folder of bootstrap will contain all pre-compiled CSS and JavaScript. Just create index.html inside it and start learning the curves of Bootstraps.

Note: JavaScript dependencies like jQuery and Popper.js need to be downloaded & install separately.

sudo apt-get install git git clone https://github.com/twbs/bootstrap.git

Method to Install bootstrap with npm

NPM (Node Package Manager) is an open source package manager that is used for Javascript package management. It has an online database of the different package both public and private; this database refers as NPM registry. In Node.js, it comes as the default package manager and uses command line client NPM. And we can use this npm single command to download and install bootstrap packages on Ubuntu.

What is bootstrapping?

I am reading about bootstrapping and am confused because the term is used so much in tech (specially bootstrap itself as the CSS framework). But as far as I know bootstrapping in terms of Linux machines is this: http://www.tldp.org/LDP/LG/issue70/ghosh.html — Describes a way to start up a computer. Is this correct? If so, then bootstrapping is boot loading?

2 Answers 2

In the general sense, «bootstrapping» is a process through which a complex system is set up using a much simpler system. A bootstrap system (the simpler system) is in itself inherently incomplete.

Bootstrapping an OS («booting it») includes getting the computer’s firmware (BIOS, or equivalent) to run a simple program which is sometimes located on a fixed location on disk, which in turn starts more complex initialisation routines (see first and second stage bootloaders).

Bootstrapping a compiler is done by compiling a simple compiler that can handle a subset of a language in which the full compiler is written, possibly in several successive steps.

The term is also used in business and in other fields to describe the use of intermediate stages of investment/development needed to initiate later stages of increasing complexity and/or size.

Tall boots may have a tab, loop or handle at the top known as a bootstrap, allowing one to use fingers or a boot hook tool to help pulling the boots on. The saying «to pull oneself up by one’s bootstraps» was already in use during the 19th century as an example of an impossible task.

How To Install bootstrap on Debian 11

In this guide, we’ll discuss How To Install bootstrap on Debian 11. Also, we will demonstrate how to uninstall and update bootstrap .

One-liner install command

For those in a hurry, here’s a one-line installation command:

sudo apt-get update && sudo apt -y install fastdnaml

But if you are interested in the detailed steps with descriptions, the following information is for you.

What is bootstrap and what are the ways to install it?

Short description: Tool for construction of phylogenetic trees of DNA sequences

Before beginning this tutorial, you will need access to a server or computer running Debian 11. This guide was written specifically with a server running Debian 11 in mind, although it should also work on older, supported versions of the operating system.

Also, make sure you are running a regular, non-root user with sudo privileges configured on your server. When you have an account available, log in as your non-root user to begin.

There are several ways to install bootstrap on Debian 11. You can use (links are clickable):

In the following sections, we will describe each method in detail. You can choose one of them or refer to the recommended one.

Install bootstrap using apt-get

First, update apt database with apt-get using the following command.

After updating apt-get database, You can install bootstrap using apt by running the following command:

sudo apt -y install fastdnaml

Install bootstrap using apt

Because bootstrap is available in Debian 11’s default repositories, it is possible to install it from these repositories using the apt packaging system.

To begin, update apt database with apt using the following command.

After updating apt database, You can install bootstrap using apt by running the following command:

sudo apt -y install fastdnaml

Install bootstrap using aptitude

If you want to follow this method, you might need to install aptitude first since aptitude is usually not installed by default on Debian 11. Update apt database with aptitude using the following command.

After updating aptitude database, You can install bootstrap by running the following command:

sudo aptitude -y install fastdnaml

How to upgrade (update) a single package bootstrap using apt-get?

First, you will need to update packages index. Run update command as usual:

Next, to upgrade only the bootstrap, e.g. single package, you should use the following format with the apt-get command/apt command:

sudo apt-get --only-upgrade install fastdnaml

Note that this command will not install any new packages! If you wish to install the package if it doesn’t exist you may leave out —only-upgrade part.

It’s Good to Know:

sudo apt-get install fastdnaml

This will upgrade the package even if is already installed.

How To Uninstall bootstrap from Debian 11

To uninstall only the bootstrap package you can execute the following command:

sudo apt-get remove fastdnaml

Uninstall bootstrap and all its dependencies

To uninstall bootstrap and its dependencies that are no longer needed by Debian 11, you can use the command below:

sudo apt-get -y autoremove fastdnaml

Remove bootstrap with all configurations and data

To remove bootstrap configuration and data from your system you can run the following purge command:

sudo apt-get -y purge fastdnaml

Remove bootstrap completely (configurations, data and all of its dependencies)

And lastly, you can run the next command to remove absolutely everything related to bootstrap package, e.g.: configurations, data and all of its dependencies. Just use this command:

sudo apt-get -y autoremove --purge fastdnaml

Extra info and code examples

fastDNAml is a program derived from Joseph Felsenstein’s version 3.3 DNAML (part of his PHYLIP package). Users should consult the documentation for DNAML before using this program. fastDNAml is an attempt to solve the same problem as DNAML, but to do so faster and using less memory, so that larger trees and/or more bootstrap replicates become tractable. Much of fastDNAml is merely a recoding of the PHYLIP 3.3 DNAML program from PASCAL to C. Note that the homepage of this program is not available any more and so this program will probably not see any further updates.

Conclusion

You now have a full guide on how to install bootstrap using apt, apt-get and aptitude tools. Also, we showed how to update as a single package and different ways to uninstall the bootstrap from Debian 11.

Building GCC: What are the advantages and disadvantages of bootstrap?

I understand what bootstrapping a compiler build does, but I don’t understand the advantages and disadvantages for regular users. (I assume there is value for GCC maintainers.) When configuring GCC, there are two options: —enable-bootstrap and —disable-bootstrap . As I understand, for vanilla compiler builds, —enable-bootstrap is enabled by default. I cannot find anything on the advantages and disadvantages of using —disable-bootstrap . My Google-fu fails me. I assume the build will be faster, but what are the downsides? To be clear, I am doing a vanilla x86-64 Linux GCC build from v6.1.0 official sources. I ask because I see the option —disable-bootstrap used in the Linux from Scratch instructions here: http://www.linuxfromscratch.org/lfs/view/development/chapter06/gcc.html

More people need to read the Installing GCC guide by Johnathan Wakely, a GCC dev, instead of guides from the Internet. For one thing, ./contrib/download_prerequisites is a step that’s ignored in most guides in favor for hand-compiling MPC, etc. which is highly not recommended.

One disadvantage, although slight, is that —enable-bootstrap takes longer to compile. This is why I tend to pass —disable-bootstrap since compiling GCC already takes quite a long time, even if it is a very important program and one might be tempted to want to ensure it is «as correct as possible»..

—disable-bootstrap
For a native build, the default configuration is to perform a 3-stage bootstrap of the compiler when ‘make’ is invoked, testing that GCC can compile itself correctly. If you want to disable this process, you can configure with —disable-bootstrap .

—enable-bootstrap
In special cases, you may want to perform a 3-stage build even if the target and host triplets are different. This is possible when the host can run code compiled for the target (e.g. host is i686-linux, target is i486-linux). Starting from GCC 4.2, to do this you have to configure explicitly with —enable-bootstrap .

On the whole, you’re best off leaving this default well alone.

If you use —disable-bootstrap , it does a 1-stage build (per Explorer09 in a comment, but I’ve still not tried it), which could work when a 3-stage build won’t.

If you need to know more, read the documentation.
