Tutorial 2: File Management
Learn how to remove files, move directories, set permissions, and create your first bash script.
Remove hello.txt from the desktop
Working in our firstfolder directory, we'll use the absolute path to remove the file.
$ rm /home/tom/Desktop/hello.txt
Move the firstfolder to Desktop
First navigate to home directory, then move the folder to Desktop.
$ cd ~ $ mv firstfolder/ /home/tom/Desktop/
Create script.sh in firstfolder
Navigate to the moved directory and create a new script file using nano.
$ cd Desktop/firstfolder $ nano script.sh
Writing Your First Bash Script
Add this content to your script.sh file in nano:
#!/bin/bash echo "Hello! $(whoami)" echo "The current date/time is: $(date)"
