When I tried to install arduino on ubuntu, arduino site says that I can install it through terminal by typing these commands
sudo apt-get update && sudo apt-get install arduino arduino-core
And generally in Linux Debian we can install programs using terminal by typing
sudo apt-get install ${program-name}
The question is how could I know the ${program-name} needed to install without going to the program installation guide to copy the code?

The apt-cache command line tool is used for searching apt software
package cache. In simple words, this tool is used to search software
packages, collects information of packages and also used to search for
what available packages are ready for installation on Debian or Ubuntu
based systems.
To find out the package name and with it description before installing, use the ‘search‘ flag. Using “search” with apt-cache will display a list of matched packages with short description. Let’s say you would like to find out description of package ‘vsftpd‘, then command would be.
Syntax:
apt-cache search SearchTerm
$ apt-cache search vsftpd
The possible output would be:
vsftpd - lightweight, efficient FTP server written for security
ccze - A robust, modular log coloriser
ftpd - File Transfer Protocol (FTP) server
yasat - simple stupid audit tool
To find and list down all the packages starting with ‘vsftpd‘, you
could use the following command.
$ apt-cache pkgnames vsftpd
You may also want to run the results through a more, or even a grep.
For instance:
apt-cache search firefox | grep plugin
