A Bash script is a text file containing a series of commands written in the Bash (Bourne Again SHell) programming language. It is used to automate tasks in Unix-like operating systems, such as Linux and macOS.
Key Features:
- Automation: Bash scripts can automate repetitive tasks, such as file management, system monitoring, and application deployment.
- Execution: You can run a Bash script by making it executable and then executing it from the terminal.
- Scripting Language: Bash provides control structures (like loops and conditionals), functions, and variables, allowing for complex programming logic.
Basic Structure:
A simple Bash script might look like this:
#!/bin/bash
echo "Hello, World!"#!/bin/bash: This is called a shebang, indicating that the script should be run using the Bash interpreter.echo "Hello, World!": This command prints "Hello, World!" to the terminal.
Creating and Running a Bash Script:
- Create a file (e.g.,
script.sh). - Add your commands to the file.
- Make it executable:
chmod +x script.sh - Run the script:
./script.sh
