How to compare files?

To compare files in Linux, you can use the diff command. Here’s how to do it:

1. Open the Terminal.

2. Navigate to the directory where your files are located. For example:

   cd ~/project
   

3. Use the diff command to compare two files. For example:

   diff file1.txt file2.txt
   

This command will display the differences between file1.txt and file2.txt.

Example Output:

If there are differences, you might see output like: ```plaintext 1c1 < this is file1

this is file2

### Additional Options:
- Use `-u` for a unified format:
  ```bash
  diff -u file1.txt file2.txt

• Use -i to ignore case differences:

  diff -i file1.txt file2.txt
