This article mainly introduces the use of linux whereis command to display commands and related files of the path, the article is very detailed, has a certain reference value, interested friends must read it!

The whereis command is used to locate the path to related files such as the command's binaries, source code files, and man man pages.

The whereis command is very fast because it is not looking around on disk, but in a database, which is automatically created by the linux system, contains information about all local files, and is updated once a day by automatically executing the updatedb command. Because of this, the search results of the whereis command are sometimes inaccurate, such as the file you just added may not be found because the database file has not been updated.

Syntax format: whereis [parameter] [command name]

Common parameters:

-b find binaries or commands-B find binaries or commands from specified directories-m find man manual files-M find man manual files from specified directories-s find source code files only-S find source code files from specified directories

[root@linuxcool ~] # whereis ln

Ln: / usr/bin/ln / usr/share/man/man1/ln.1.gz / usr/share/man/man1p/ln.1p.gz

Displays the path to the binary program for the ln command:

[root@linuxcool] # whereis-b ln

Ln: / usr/bin/ln

Displays the path to the man man page for the ln command:
