Linux File Management Whereis

Whereis Search program Simple and quick Command English original meaning

Command format

Command function

• The Whereis command locates the location of the executable file, the source code file, and the Help file in the file system. The properties of these files should belong to the original code, binary files, or Help files. The Whereis program also has the ability to search for source code, specify alternate search paths, and search for unusual items. Whereis find is very fast, because the Linux system will record all the files in the system in a database file, when using Whereis, will look for data from the database, rather than by traversing the hard disk to find, the efficiency will naturally be very high. However, the database file is not updated in real time and is updated once a week by default, so when we use Whereis to find files, we sometimes find data that has been deleted, or just created the file, but cannot find it because the database file was not updated.
