find by name, type, and size in Linux CLI - Mini Project: Build & Apply

Find Files by Name, Type, and Size Using Linux CLI

📖 Scenario: You are organizing files on your Linux system. You want to find files based on their name, type, and size to manage storage efficiently.

🎯 Goal: Build a Linux command using find to search files by exact name, file type, and minimum size.

📋 What You'll Learn

Use the find command

Search for files with a specific name

Filter by file type (regular file or directory)

Filter files by minimum size

💡 Why This Matters

🌍 Real World

System administrators and users often need to find files quickly based on specific criteria to manage disk space or organize data.

💼 Career

Knowing how to use the <code>find</code> command with filters is essential for Linux system administration, scripting, and automation tasks.

1

Create a directory with files for testing

Create a directory called test_dir and inside it create three files named report.txt, data.csv, and summary.log.

Linux CLI

# Create directory and files
# Your code here

Need a hint?

Use mkdir to create a directory and touch to create empty files.

2

Add a size filter variable

Create a variable called min_size and set it to 1k to represent minimum file size of 1 kilobyte.

Linux CLI

mkdir test_dir
cd test_dir
touch report.txt data.csv summary.log

# Set minimum size variable
# Your code here

Need a hint?

Assign min_size=1k to set the size filter.

3

Write the find command with name, type, and size filters

Write a find command to search in test_dir for regular files named report.txt with size greater than or equal to $min_size.

Linux CLI

mkdir test_dir
cd test_dir
touch report.txt data.csv summary.log
min_size=1k

# Write find command here
# Your code here

Need a hint?

Use find . -type f -name report.txt -size +$min_size to filter files.

4

Display the result of the find command

Run the find command from Step 3 and print the output to show the matching files.

Linux CLI

mkdir test_dir
cd test_dir
touch report.txt data.csv summary.log
min_size=1k
find . -type f -name report.txt -size +$min_size

# Print the output
# Your code here

Need a hint?

The output should show ./report.txt if the file matches the criteria.
