A man page for fork, for example, is in the System Calls section that has number 2:man 2 forkHow do you see what else is section 2 without resorting to Google?
How do you output a list of all man pages in a particular section?
shell;man
This command lists the sorted names of all the entries in the given section:man -aWS 1 \* | xargs basename | sed 's/\.[^.]*$//' | sort -uIf you want to see the pathnames, use:man -aWS 1 \* | sed 's/\.[^.]*$//' | sortThis tells man to search a section for all commands using the wildcard pattern * (backslash-quoted so the shell doesn't interpret it). -a finds all matches, -W prints the pathnames instead of displaying the pages, and -S 1 specifies section one. Change the 1 to whatever section you want to search.The sed command strips the filename extensions; remove it if you want to see the complete filenames. sort sorts the results (-u removes duplicates).For convenient reuse, this defines a Bash shell function:function mansect { man -aWS ${1?man section not provided} \* | xargs basename | sed 's/\.[^.]*$//' | sort -u; }For example, you can invoke it as mansect 3 to see the entries in section three.[Tested on macOS.]
