Note: The database is recomputed periodically (usually weekly or daily): `locate "{{pattern}}"` - Look for a pattern case-insensitively: `locate {{[-i|--ignore-case]}} "{{pattern}}"` - Look for a file by its exact filename (a pattern containing no globbing characters is interpreted as `*pattern*`): `locate "*/{{filename}}"` - Recompute the database. You need to do it if you want to find recently added files: `sudo updatedb`
