The command "man -f ${command}" is used to display the manual pages associated with a specified command. Here's a breakdown of each element in the command:
-
"man" is the command itself, which stands for manual. It is used to access the system's manual pages, which contain detailed information about various commands, utilities, and functions available on a Unix-like operating system.
-
"-f" is an option or flag for the "man" command. In this case, it stands for "whatis" or "apropos." When used with "man", it searches the manual pages' database for the specified command and provides a brief description or summary of what the command does. It helps in finding commands when you have a general idea of what you want to achieve but don't know the specific command name.
-
"${command}" is a placeholder indicating that you should replace it with the actual command you want to search for in the manual pages. For example, if you want to find information about the "ls" command, you would replace "${command}" with "ls" like this: "man -f ls".
