Bash is the shell (or interpreter) for the GNU operating system. It stands for “Bourne-Again SHell”—a nod to its predecessor, sh, and to the fact that it reimagines many of its features. Bash provide many tools like variables, functions, and loops enhances capability of user.
How can you utilize such powerful tools?
First of all, Bash scripts are simply text files with the .sh extension. Every Bash script begins with a special line called a shebang: #!/bin/bash
This line tells your system to use Bash to interpret the file. After the shebang, you can include any commands you would normally run in a terminal. Bash lets you combine these commands into scripts that automate repetitive tasks.
Linux@Operating-System:~$ cat Hi.sh
#!/bin/bash
echo “Good to see you again boss!”
Linux@Operating-System:$ ./Hi.sh
Linux@Operating-System:$ Good to see you again boss!
Linux@Operating-System:$ cat conclusion.txt
This example demonstrates how a Bash script is structured and run. With Bash, you’ll discover that its flexibility can save you time and effort. Start small, and gradually build scripts that handle more complex tasks—remember, Bash is a powerful ally in automating your workflow!
Feel free to adjust and expand this example to suit your needs.
