updatedb [OPTIONS]

updatedb creates or updates the database used by the locate command. It scans the filesystem and builds an index of all filenames for fast searching.
The command is usually run daily by cron to keep the database current. Manual execution is needed to index newly created files before the next scheduled update.

-v, --verbose

Display filenames as they are found

Exclude specified paths from database

Exclude specified filesystem types

Write to specified database file

/etc/updatedb.conf

Controls which paths, filesystem types, and file patterns are included or excluded from the database.

Requires root privileges for full filesystem access. Initial scan can take several minutes on large filesystems. Network filesystems are typically excluded by default.
