Locate (Unix)

codice_1 is a Unix utility which serves to find files on filesystems. It searches through a prebuilt database of files generated by the codice_2 command or by a daemon and compressed using incremental encoding. It operates significantly faster than codice_3, but requires regular updating of the database. This sacrifices overall efficiency (because of the regular interrogation of filesystems even when no user needs information) and absolute accuracy (since the database does not update in real time) for significant speed improvements, particularly on very large filesystems.
codice_1 was first created in 1982. The BSD and GNU Findutils versions derive from the original implementation. Their primary database is world-readable, so the index is built as an unprivileged user. codice_1 command is also included in MacOS.
codice_6 (Merging Locate) and the earlier codice_7 (Secure Locate) use a restricted-access database, only showing filenames accessible to the user.
