How can you execute a script in Linux?

Executing a script in Linux often requires that you run it within a command-line interface. The most direct way to execute a script file, provided that it has been given the appropriate execute permissions, is by using the ./ prefix followed by the script's name. This tells the shell to look for the script in the current working directory and execute it.

The command ./script.sh effectively invokes the script by specifying its location relative to your current directory, allowing Linux to execute the commands contained within the script. For this method to work, you need to ensure that the script has the executable permission set, which can typically be done using the chmod +x script.sh command.

The other methods mentioned in the question do not lead to successful execution of the script in a straightforward or standard manner on a Linux system. Double-clicking the script file might work in some graphical desktop environments, but it does not guarantee execution in a terminal context or in environments that do not support such interactions. Simply typing script.sh in the terminal may not work unless the script is in your PATH or you specify its relative path, while opening the script in a text editor is simply for viewing or editing the contents, not executing it. Therefore, the correct
