man:tldr:546c3
The man
command is used on Unix-like systems to display manual pages, which provide detailed information, explanations, and usage examples for various commands, utilities, and system components.
The -k
option in the given command specifies that a keyword search should be conducted within the manual pages. It allows you to find commands or topics related to a specific keyword.
The ${search_string}
is a placeholder for the keyword you want to search for. You replace it with the actual keyword or phrase you are interested in. For example, if you want to search for information related to "network," you would replace ${search_string}
with "network" like this:
man -k "network"
By executing this command, the system will search through the available manual pages for commands or topics that contain the keyword "network" and display a list of relevant matches. This helps you to quickly find the manuals you need for the given keyword.
