Navigation and File Management

Understanding how to move around and handle files is the first step in using the terminal. The pwd command prints your current working directory, while ls lists the contents of that directory. To change directories, use cd followed by the path. You can create new folders with mkdir and empty files with touch. To copy files, use cp, and to move or rename them, use mv. When you need to delete files or directories, the rm command is used, but it should be handled with care as deleted items are not sent to a trash bin.

System Administration and Permissions

Managing system privileges and installing software requires specific commands. The sudo command allows you to execute tasks with administrative rights. To install new applications, Ubuntu uses the apt package manager; for example, sudo apt update refreshes your package list, and sudo apt install package_name installs software. File permissions are managed with chmod, which changes access rights, and chown, which changes file ownership. To monitor system performance, top displays active processes, and ps shows a snapshot of current processes running on your machine.
