Este capítulo describe cómo configurar el entorno SED en su sistema GNU / Linux.

Instalación mediante el Administrador de paquetes

Generalmente, SED está disponible de forma predeterminada en la mayoría de las distribuciones GNU / Linux. Utilizarwhichcomando para identificar si está presente en su sistema o no. De lo contrario, instale SED en GNU / Linux basado en Debian usandoapt administrador de paquetes de la siguiente manera:

[jerry]$ sudo apt-get install sed

Después de la instalación, asegúrese de que se pueda acceder a SED a través de la línea de comandos.

[jerry]$ sed --version

Al ejecutar el código anterior, obtiene el siguiente resultado:

          . Be sure to include the word "sed" somewhere in the "Subject:" field.

Similarly, to install SED on RPM based GNU/Linux, use yum package manager as follows:
 [root]# yum -y install sed
 After installation, ensure that SED is accessible via command line.
 [root]# sed --version
 On executing the above code, you get the following result:
 GNU sed version 4.2.1

 Installation from Source Code
 As GNU SED is a part of the GNU project, its source code is available for free download. We have already seen how to install SED using package manager. Let us now understand how to install SED from its source code.
 The following installation is applicable to any GNU/Linux software, and for most other freely-available programs as well. Here are the installation steps: 
      
      Download the source code from an authentic place. The command-line utility wget serves this purpose. 
      [jerry]$ wget ftp://ftp.gnu.org/gnu/sed/sed-4.2.2.tar.bz2
 
      Decompress and extract the downloaded source code. 
      [jerry]$ tar xvf sed-4.2.2.tar.bz2 
 
      Change into the directory and run configure. 
      [jerry]$ ./configure 
 
      Upon successful completion, the configure generates Makefile. To compile the source code, issue a make command. 
      [jerry]$ make
 
      You can run the test suite to ensure the build is clean. This is an optional step. 
      [jerry]$ make check 
 
      Finally, install the SED utility. Make sure you have superuser privileges. 
      [jerry]$ sudo make install 
 
     
 That is it! You have successfully compiled and installed SED. Verify it by executing the sed command as follows:
 [jerry]$ sed --version
 On executing the above code, you get the following result:
 sed (GNU sed) 4.2.2

       .
