## **What is File Manipulation?**
File manipulation is a fundamental aspect of computer systems and is pivotal in interacting with our digital world. It involves performing various operations on files and directories, allowing users to create, modify, organize, and delete digital assets within a file system. These files can be documents, scripts, programs, configuration files, or even directories.

## **Functions of File Manipulation in Linux**
File manipulation encompasses many functions in Linux:

➔     **Creating Files and Directories:** Users can create new files or directories using commands like touch for files and mkdir for directories. For example

mkdir newfolder        # Creates a new directory

rmdir # Removing a directory

➔     **Viewing File Contents:** To see the contents of a file, you can use commands like cat in Linux. This is akin to opening a document to read its contents. For example:

cat myfile.txt          # Displays the content of the file

➔    ** Modifying Files:** File modification involves changing a file's content, attributes, or permissions. It includes tasks like editing a file's content, altering permissions, renaming, or updating metadata. For example:

nano myfile.txt    # Opens a text editor to modify the file 
chmod 755 script.sh # Changes file permissions

➔     **Copying and Moving Files:** You can duplicate files using commands like cp and move them from one location to another using mv. For example:

cp file1.txt copy_of_file1.txt # Copies a file

➔     **Deleting Files:** Deleting files removes them from the file system, freeing up storage space. Deleted files often end up in a trash or recycle bin before being permanently removed. For example:

rm oldfile.txt  # Deletes a file
