Navigation and File Management

Understanding where you are and how to move files is fundamental. Use pwd to print the working directory and ls to list contents. Navigate folders with cd folder_name and return to the home directory with cd ~. Create new directories using mkdir and remove them with rmdir. To copy files, use cp source destination, and to move or rename them, use mv source destination. Delete files cautiously with rm filename.

System Administration and Packages

Managing software and system privileges requires specific commands. Prepend sudo to execute commands with administrative rights. Install new applications using sudo apt install package_name and update your package list with sudo apt update. Monitor system performance in real-time by typing top or htop, and check disk space usage with df -h.

Permissions and Text Editing

Controlling access and editing configuration files are critical skills. Change file permissions with chmod and modify ownership using chown. For text editing within the terminal, nano is user-friendly for beginners, while vim offers advanced features for experienced users. Always verify changes by viewing file contents with cat filename or less filename.
