How to Install Applications on Linux OS


In comparison to Windows and other OS, Linux is an open-source program with several distributions. Each distribution handles the installation of applications differently, depending on factors like package manager. Since Linux applications are coded and developed in different environments, certain pre-installed binaries as well as files are required on the system wherein a typical application is to be run.
As an illustration, the installation of an application on Red Hat would differ from that of Debian Linux – the former makes use of RPM that is Red Hat Package Manager while the latter works with dev package. So, first identify the minimum installation requirements for the kind of Linux distribution you have on your computer.
Now, using the Red Hat Linux as the version installed on a PC, here are the steps required for applications to be installed.
Red Hat, as noted earlier on, uses RPM to install programs, thus making it simple to perform the removal and the addition of an application through its user-friendly graphical package management tools.
For the installation to initiate, ensure that you’re in the root account of the system. Otherwise, it won’t start. You would get an error dialog display.
Once you boot the PC to the desktop, click the “start” menu, then select “system” from the displayed list. From there, go to “setting” where you would see the “Add /Remove” tab.
From here, you can select the application you want to install or remove by accessing the sections and sub-sections in the details menu entry. It’s a bit like you would do with Windows’ Control Panel.
Alternatively, the command line can be used to add and remove applications from a Linux system. Firstly, ensure that the source file of the program to be installed is already downloaded to the computer, and the source file should be downloaded in the tar-gzipped extension
Then, unzip it with this command:
# tar – zxvf wp-1.0rcl.tar.gz
NB: WP.tar.gz is the sample file name.
The above command creates a directory consisting of all the files, e.g WP- 1.0rclin. Then, create another command:
# / configure
It simply begins the build-up of make files. Provided there is no installation error at this point, you can issue the next command line:
# make
Afterwards, make a change to the system’s root user mode through su command followed by the command for the installation of executable files in appropriate directories. Here is the command line:
# make install
As for the removal of the application, just issue the command “# make clean”.
When you have successfully installed the files, you can then run the application by issuing its command name, e.g. WP (word processor as in our example). Nonetheless, other essential utilities like auto-make, make and compilers must have been installed on the PC before make file can be created.
Finally, it is advisable that you take caution when giving these commands by reading necessary documentations that are associated with the software and computer system. Generally, with these steps, you should be able to install applications on your Linux system.
