Creating a Bash File
To create a bash script file with the .sh extension. For example, "my_script.sh" Add a shebang line at the beginning of the script to specify the interpreter. In this case, we will use bash.
#!/user/bin/bashWrite your script commands under the shebang line. Each command should be on a new line. For example, let's print "Hello, World!" and list the files in the current directory.
#!/user/bin/bash echo "Hello, World!" ls
Save your script file.
Open a terminal and navigate to the directory where your script file is located. Give the script file execute permissions by running the following command:
chmod +x my_script.sh chmod u+rwx my_script.sh . . .
removing permission
chmod u-w my_script.sh chmod u-r my_script.sh . . .
Now you can run your script by executing the following command:
./my_script.sh
This will execute your script and display the output in your terminal.
Remember to replace my_script.sh with the actual name of your script file.
- EXAMPLE:
#!/user/bin/bash greeting = "welcome" user = $(whoami) day = $(date + %A) echo "greeting back $user! Today is $day, which is the best day of the entire week!" echo "your bash shell version is $BASH_VERSION. Enjoy!"
