Linux Learning note 6 locate/slocate MV

Both the locate command and the Slocate command are used to locate files or directories.

Locate is different from find: find is to go to the hard drive, locate only in/var/lib/slocate database. This database contains all the local file information. The Linux system automatically creates this database and updates it automatically once a day, so you can't find the latest changed files using the Locate command. In order to avoid this situation, you can use the UpdateDB command before using locate, manually update the database, locate faster than find, it is not really looking, but to check the database,

[Email protected]/]# UpdateDB

[Email protected]/]#
