Linux File Operation Commands

In Linux, everything is treated as a file, whether it is a text document, a program, or even a device. To manage files and directories (folders) effectively, Linux provides a set of simple yet powerful commands. These commands help users create, copy, move, and delete files and directories through the command-line interface (CLI). Understanding these basic file operations is essential for anyone beginning their journey with Linux.

Example:

$ cp file1.txt backup/

This command copies file1.txt to the backup directory.

mv Command

The mv command is used to move or rename files and directories.

Example:

$ mv oldname.txt newname.txt

This command renames oldname.txt to newname.txt.

rm Command

The rm command is used to remove (delete) files and directories.

Example:

$ rm unwanted.txt

This command deletes the file named unwanted.txt.

touch Command

The touch command is used to create an empty file or update the timestamp of an existing file.

Example:

$ touch newfile.txt

This command creates a new empty file named newfile.txt.
