How To Compile and Install from Source on Ubuntu


Ubuntu and other Linux distributions have extensive package repositories to save you the trouble of compiling anything yourself. Still, sometimes you’ll find an obscure application or a new version of a program that you’ll have to compile from source.
You don’t have to be a programmer to build a program from source and install it on your system; you only have to know the basics. With just a few commands, you can build from source like a pro.
Installing the Required Software
Installing the build-essential package in Ubuntu’s package repositories automatically installs the basic software you’ll need to compile from source, like the GCC compiler and other utilities. Install it by running the following command in a terminal:
    $sudo apt-get install build-essential
Getting a Source Package
Now you’ll need your desired application’s source code. These packages are usually in compressed files with the .tar.gz or .tar.bz2 file extensions.
As an example, let’s try compiling gawk from source. Locate the program’s .tar.gz or .tar.bz2 file and save it to your computer.( You can also use wget utility to download)
$ wget http://ftp.gnu.org/gnu/gawk/gawk-4.1.1.tar.xz
A .tar.gz or .tar.bz2 is like a .zip file. To use it, we’ll have to extract its contents.
Use this command to extract a .tar.gz file:
tar -xzvf file.tar.gz
Or use this command to extract a .tar.bz2 file:
tar -xjvf file.tar.bz2
eg: $ tar xvf gawk-4.1.1.tar.xz
Resolving Dependencies
Once you’re in the extracted directory, run the following command:
./configure
Once ./configure completes successfully, you’re ready to compile and install the package.
Compiling and Installing
Use the following command to compile the program:
$ make
After this command finishes, the program is successfully compiled — but it’s not installed. Use the following command to install it to your system:
$ sudo make install
That is it! You have successfully compiled and installed AWK. Verify it by executing the awk command as follows −
$ which awk

Writing a Bash Shell Script

Bash shell scripts in Linux are text files that contain a series of commands that can be executed by the Bash shell. Bash (Bourne Again Shell) is a popular shell in Linux and UNIX systems, and shell scripts are used to automate tasks, configure systems, or perform a sequence of operations. How to Write a Bash Shell Script Create a New File: You can create a new script using any text editor like nano , vim , or gedit . gedit myscript.sh Write the Script: A basic shell script begins with a "shebang" ( #!/bin/bash ) to specify the interpreter that will be used to execute the script. The rest of the file contains the commands to be run. Example of a simple script: #!/bin/bash # This is a comment echo "Hello, World!" # Print "Hello, World!" #!/bin/bash : Specifies that the script will be executed using the Bash shell. echo "Hello, World!" : A command that prints the string "Hello, World!" to the terminal. Comments: Any line starting ...

Different syntax for writing arithmetic expressions in bash shell

#!/bin/bash echo "Enter two numbers" read a b s=`expr $a + $b` echo "Sum1=$s" s=$[$a+$b] echo "sum2=$s" ((s=$a+$b)) echo "sum3=$s" ((s=a+b)) echo "sum3=$s" let s=$a+$b echo "sum4=$s" let s=a+b echo "sum4=$s" Note:bash shell support only integer arithmetic.zsh support operations on real numbers.We can use bc in bash shell to do real arithmetic. Eg: echo "$a*$b"|bc # where a and b are real Mathematical Operators With Integers Operator Description Example Evaluates To + Addition echo $(( 20 + 5 )) 25 - Subtraction echo $(( 20 - 5 )) 15 / Division echo $(( 20 / 5 )) 4 * Multiplication echo $(( 20 * 5 )) 100  % Modulus echo $(( 20 % 3 )) 2 ++ post-increment (add variable value by 1) x=5 echo $(( x++ )) echo $(( x++ )) 5 6 -- post-decrement (subtract variable value by 1) x=5 echo $(( x-- )) 4 ** Exponentiation x=2 y=3 echo $(( x ** y )) 8

Flow Control in shell script - if and case statements

Shell script usually consist of sequence of commands that starts at the first line and continues line by line until it reaches the end. Most programs do much more than this. They make decisions and perform different actions depending on conditions. The shell provides several commands that we can use to control the flow of execution in our program. In this lesson, we will look at the following:  test if case exit   test The test command is used most often with the if command to perform true/false decisions. The command is unusual in that it has two different syntactic forms: # First form test expression # Second form [ expression ] The test command works simply. If the given expression is true, test exits with a status of zero; otherwise it exits with a status of 1. Common numerical test conditions -gt   Greater than -lt    Less than -ge  Greater than or equal to -le    Less than or equal to -eq   Equal to -ne...
