The “whereis” command in Linux is used to locate the binary, source, and manual page files for a specific command or file. The command takes the name of a command or file as an argument, and it will display the location of the corresponding files.

Here is an example of using the “whereis” command:

$ whereis ls

This command will display the location of the binary, source, and manual page files for the “ls” command. The output will be in the format: command: binary_location source_location manual_location

Here is another example

$ whereis python3

This command will show the location of the binary, source, and manual page files for python3.

In some cases, the command may not find the source and manual page files, in that case the output will be like command: binary_location

You can also use whereis command to find files in a specific directory

$ whereis -b /usr/bin -f ls

This command will display the location of the binary file of ls command in the /usr/bin directory.

You can use -m option to search for man pages and -s option to search for source code.
