Locate and find: find file commands in two Linux systems-general Linux technology-Linux technology and application information. The following is a detailed description. If you want to execute a file search task on the command line interface for the first time switching to Linux, you need to know the commands locate and find. Although both of these commands can be used to search for files, they have their own advantages.

Locate: This Command requires the database indexed in the background to support running. In Ubuntu, the database file is located in/var/cache/locate/locatedb. Generally, this database file is automatically updated through cron every day. If the update is unfortunately not obtained, You can execute sudo updatedb to manually update the update.

If you want to find a file named linux.html in the system, you can execute the command: locate linux.html. The locate search speed is very fast, and the results will be listed later. Locate has a very useful option-r, which allows you to use regular expressions when searching for files.

For example, if you want to find the linux.html file in the/root directory, you can run find/-name linux.html. In addition to searching for files by file name, you can also use the-size n option to specify the file size), time (for example,-atime n indicates to search for files accessed n days ago) to search for files.

In addition, the find command also supports regular expressions when searching files. You only need to specify the-regex option.
