The which command searches for files that meet the conditions in the directory set by the Environment Variable PATH. That is to say, by using the which command, you can see whether a system command exists and where the command is executed.

 

Whereis command

It is used to locate the path of the binary program, source code file, man manual page, and other related files of the command.

 

Locate/slocate command

Used to find files or directories.

 

Type COMMAND

Displays the type of a specified command and determines whether the command is an internal command or an external command.
