Final answer:
The 'type' command in Unix-like systems provides information about a command, including its type, complete path, and sometimes the location of its man pages. 'what is the command gives a one-line description, and 'man -w' gives the path to the man page.
Step-by-step explanation:
The command you are asking about is known as type, which is used in Linux and Unix-like operating systems. When you enter type command_name, it displays all the information about what type of command it is (alias, keyword, function, built-in, or file), its complete path, and sometimes the location of the associated man pages if it is a file-type command. For instance, type ls will show you that ls is typically aliased to 'ls --color=auto' and the binary is located at /bin/ls. Another command that provides details about commands, including the path and manual page location, is whatis. The what is command_name command gives you a one-line description which is sourced from the man page of the command. Additionally, man -w command_name displays the path to the man page of the command.
