2024, February 14
3. File Management System Operations
File Management System (FMS) is an essential component of an operating system that organizes, stores, retrieves, and manages data files on a computer. This practical involves using command-line tools in Kali Linux to perform basic file operations.
3.1. Creating, Listing, and Removing a File
Create a file, list it, and then remove it to demonstrate basic file operations:
touch example.txt # Create a new file
ls -l # List the file
rm example.txt # Remove the file
ls -l # List the file
3.2. Working with Directories
Create a directory, list it, and then remove it:
mkdir dir # Create a new directory
ls -l # List directories to check if directory created
rmdir dir # Remove the directory
ls -l # List directories to check if directory removed
3.3. Copying and Moving Files
Create a file, copy it to a new file, move the new file to a new name, and then clean up:
touch original.txt # Create a new file
cp original.txt copy.txt # Copy the file to a new file
ls -l # List files to check if copied
mv copy.txt moved.txt # Move the copied file to a new name
ls -l # List files to check if moved
rm original.txt moved.txt # Remove both files
ls -l # List files to check if removed
3.4. Directory Operations with Content
Create a directory with a file in it, copy the directory, move the copied directory, and then remove everything:
mkdir testDir # Create a directory and a file within it
touch testDir/file.txt
ls -l # List the directory
ls -l testDir # List the directory and file
cp -r testDir copiedDir # Copy the directory recursively
ls -l # List the directory
mv copiedDir movedDir # Move the copied directory
ls -l # List the directory
rm -r testDir movedDir # Remove directories and their contents
ls -l # List the directory
3.5. Viewing File Content
Create a file, add text, view the content, and then remove the file:
nano viewfile.txt # Create a new file and add 10 lines of text to the file and save it using 'CTRL + X' and 'Y' (yes), 'Enter' in sequence.
cat viewfile.txt | wc -l # Count the number of lines in the file
tail -n 2 viewfile.txt # Display last 2 lines of content of the file
cat viewfile.txt # Display the content of the file
rm viewfile.txt # Remove the file
