Linux Fundamentals - Adding Path to the Scripts into the PATH Variable

The video tutorial explains how to execute a script using absolute or relative paths and how to make it accessible from any directory by updating the PATH variable. It covers creating a bin folder, moving the script into it, and modifying the PATH variable to include the bin folder. The tutorial also demonstrates renaming the script without an extension and executing it successfully. The video concludes with a brief overview of executable scripts and permissions, setting the stage for a discussion on networking in Linux systems.

What is the purpose of modifying the PATH variable when executing scripts?

• To allow script execution from any directory

• To increase script execution speed

• To prevent script execution errors

• To change the script's content

• The script becomes non-executable

• The script can still be executed if PATH is set correctly

• The script is automatically renamed

• The script's content is deleted

What is a key requirement for executing a script from any location?

• The script must be written in Python

• The script must have executable permissions
