How does Linux handle different cases in commands?

Linux is case-sensitive, which means that it treats commands, file names, and directory names with different cases as distinct entities. For example:

• File.txt and file.txt are considered two different files.
• The command ls (to list directory contents) is different from LS or Ls.

When using commands, you must use the correct case as defined by the system. For instance, if you want to change a directory, you would use cd Documents, not cd documents if the directory is named "Documents".

This case sensitivity applies to all aspects of the Linux environment, including commands, options, and file paths. Always ensure you use the correct case to avoid errors.
