Basic Linux Commands

1. 
   pwd — When you first open the terminal, you are in the home directory of your user. To know which directory you are in, you can use the “pwd” command. It gives us the absolute path, which means the path that starts from the root. The root is the base of the Linux file system and is denoted by a forward slash( / ). The user directory is usually something like “/home/username”.

1. cd — Use the “cd” command to go to a directory. “cd” expects directory name or path of new directory as input.

1. rm – Use the rm command to delete a file. Use “rm -r” to recursively delete all files within a specific directory.

1. cp — Use the cp command to copy files through the command line.

9.cat — Use the cat command to display the contents of a file. It is usually used to easily view programs.
