Are file and directory names case-sensitive in Linux?

Yes, file and directory names are case-sensitive in Linux. This means that file.txt, File.txt, and FILE.TXT are considered three distinct files. Similarly, directories are also case-sensitive, so Documents and documents would refer to different directories.

Example:

• If you create a file named example.txt, you cannot access it using Example.txt or EXAMPLE.TXT—you must use the exact case.

Why Case Sensitivity Matters:

1. Consistency: It helps maintain consistency in naming conventions, especially in programming and scripting.
2. Avoiding Conflicts: Different cases allow for more unique naming options, reducing the likelihood of name conflicts.

Practical Tip:

When working in the terminal, always pay attention to the case of file and directory names to avoid errors. If you’re unsure, you can use the ls command to list files and check their exact names.
