Sed tutorial (i) Installation configuration

Describes how to set up an SED environment in a gnu/linux system

Install using the Package Manager

In general, SED is provided by default in most Gnu/linux distributions. Use this command to determine whether it exists on your system. If not, then in Debian-based gnu/linux you can use the APT Package Manager as follows to install SED:

[root]# sudo apt-get

After installation, ensure that SED can be accessed from the command line.

[Root]#--versio   

Executing the above code, you will get the following result:

sed (GNU sed) 4.2.2 Copyright (C) Free Software Foundation, Inc. License gplv3+: GNU GPL version 3 or later 
Similarly, the Gnu/linux-based RPM installation sed, with the Yum Package Manager, looks like this:
[Root]#-y install sed   
After installation, ensure that SED can be accessed from the command line.
[Root]#--version   
Executing the above code, you will get the following result:

Installing from source code
Since the GNU SED is part of the GNU program, its source code is free to download. We have seen how to install SED using the Package Manager. Now, learn how to install sed from source code.
The installation below applies to any Gnu/linux software, and most other free-to-use programs. Here are the installation steps:
1th Step-Download the source code from a real place. The command-line utility wget serves this purpose.
[root]# wget ftp://ftp.gnu.org/gnu/sed/sed-4.2.2.tar.bz2    
2nd Step-Unzip and decompress the source code of the download.
[root]# tar xvf sed-4.2.  2.tar.         
3rd Step-Change into directory and run configuration.
[root]#./    
4th Step-Once successfully completed, the configuration generates the makefile file. Compile the source code and use the Make command.
[root]#    make
5th Step-You can run a test suite to make sure that the build is clean. This is an optional step.
[root]#   
6th Step-Finally, install the SED utility. Make sure that you have superuser privileges.
[root]#   
We have successfully compiled and installed SED. By executing the SED command, verify the following:
[Root]#--version   
Executing the above code, you will get the following result:
