Furthermore, file and directory names are uppercase in this system, even though systems that use the 8.3 standard are usually case-insensitive (making CamelCap.tpu equivalent to the name CAMELCAP.TPU). has no significance (that is, myfile and myfile. If a file name has no extension, a trailing. For systems that only support 8.3 filenames, excess characters are ignored. Similar 8.3 file naming schemes have also existed on earlier CP/M, TRS-80, Atari, and some Data General and Digital Equipment Corporation minicomputer operating systems.Ĩ.3 filenames are limited to at most eight characters (after any directory specifier), followed optionally by a filename extension consisting of a period. The filename convention is limited by the FAT file system. ![]() It is also used in modern Microsoft operating systems as an alternate filename to the long filename, to provide compatibility with legacy programs.

The locate command will return all file names that contain the pattern as a substring.įor example, to find all files that contain the word “yes” in their names, you can use this command: locate yes. The pattern is a string of characters that you want to search for in the file names.

For example, -not -name “*.txt” matches files that don’t end with. -not: Negates the following expression.The find command has a number of useful features and settings that you can explore by reading its manual page via the terminal ( man find).
