Unix/Linux CLI Commands 3.0

Unix/Linux CLI commands are used to interact with the operating system through a command-line interface, allowing users to perform a variety of tasks such as file management, system monitoring, and software installation.

You can usually open the terminal by searching for 'Terminal' in your applications menu or by using a keyboard shortcut like Ctrl+Alt+T.

'ls' lists files and directories in the current directory, whereas 'ls -l' provides a detailed listing that includes permissions, number of links, owner name, group name, file size, and last modified date.

You can copy files using the 'cp' command. For example, 'cp source_file destination_file' will copy 'source_file' to 'destination_file'.

You use the 'cd' command. For example, 'cd /path/to/directory' will change your current directory to the specified path.

You can use the 'cat', 'more', or 'less' commands. For example, 'cat filename.txt' will show the contents of the file on your terminal.

A package manager is a tool that automates the process of installing, upgrading, configuring, and removing software packages. In Unix/Linux systems, commands like 'apt', 'yum', or 'pacman' are used with package managers.

You can use the 'find' command. For example, 'find /path -name filename.txt' will search for files named 'filename.txt' starting from '/path'.

'chmod' changes the file permissions for users. For example, 'chmod 755 filename' sets read, write, and execute permissions for the owner and read and execute for others.

You can use the 'ps' command or the more interactive 'top' command to view active processes running on your system.
