This article covers how to easily create a shell script and automate repetitive jobs in #Linux. Shell scripts are just a series of commands that you add in a file and run them together.
To write and execute a #script:
Open the #terminal. Go to the directory where you want to create your script.
Create a file with . sh extension.
Write the script in the file using an editor.
Make the script executable with command chmod +x <fileName>.
Run the script using ./<fileName>.
#Shell is a #UNIX term for an interface between a user and an operating system service.
Shell provides users with an interface and accepts human-readable commands into the system and executes those commands which can run automatically and give the program's output in a shell script.
