What command can you use to search for files by name in Linux?

The command used to search for files by name in Linux is "find." This command is powerful and versatile, allowing users to search for files and directories by various criteria, including name, type, size, and more. When searching for files by name, the "find" command can be combined with options such as "-name" or "-iname" for case-insensitive name matching.

For instance, the command find /path/to/directory -name "filename.txt" will search for a file named "filename.txt" within the specified directory and all its subdirectories. The "find" command traverses the directory structure and provides precise control over search parameters, making it highly effective for locating files.

While "locate" is another command that can find files by name, it relies on a prebuilt database and may not reflect real-time changes to the filesystem. "grep" is primarily used for searching text within files rather than locating files themselves, and "search" is not a standard command in Linux for this purpose. Therefore, "find" is the most suitable command for direct file name searches within the filesystem.
