What command can be used to search through the manual pages?

The command that can be used to search through the manual pages is "man -k keyword." This command utilizes the '-k' option, which enables the user to search the manual page descriptions for the specified keyword. It looks through the short descriptions and manual page names for occurrences of the keyword and provides a list of related manual entries. This is particularly useful when you are unsure of the exact command you are looking for, but you have a keyword that relates to it.

The other commands do not perform a search through the manual pages in the way intended. For example, "man keyword" displays the manual page associated with the exact "keyword" if it exists, but it does not search through all manual pages for related content. The "man -s keyword" command attempts to search within a specific section of the manual pages, which can be useful but again does not perform a search across all manual descriptions. Lastly, "search man keyword" is not a valid command in the context of accessing manual pages on Linux, so it wouldn't work at all.

Using "man -k" effectively allows for searching and is a valuable tool in a user’s command-line toolkit for finding relevant command manual entries based on partial or descriptive keyword input.
