pwd - Print Working Directory
To know your current location within the file system, use the pwd command. It reveals the absolute path of the directory you're currently in.

Working with Files and Directories

Creating, copying, moving, and deleting files and directories are common tasks when working with Linux. Familiarize yourself with these commands to perform these operations effortlessly.

mkdir - Make Directory
To create a new directory, use the mkdir command followed by the name of the directory you want to create.

touch - Create a File

kill - Terminate a Process
To terminate a process, use the kill command followed by the process ID (PID) of the program you want to stop.

top - Monitor System Activity
To get an overview of system activity, including running processes and resource usage, use the top command. It provides real-time information and can help diagnose performance issues.

Advanced Command Features

Linux commands offer various advanced features that can enhance your productivity and efficiency. Let's explore a few of them.

Redirection with > and >>
To redirect command output to a file, use the > symbol followed by the desired file name. You can also append output to an existing file using >>.

Piping with |
To redirect the output of one command as input to another command, use the | symbol. This allows you to chain commands together and perform complex operations.

Command History with history
