$ man ls | ./hae "how to show file sizes" -n 1 -hl                                                                   
$ man ls | grep -C 5 -E 'the following information'                                                                  
       By default, ls lists one entry per line to standard output; the exceptions are to terminals or when the -C or -x options are specified.

       File information is displayed with one or more ⟨blank⟩s separating the information associated with the -i, -s, and -l options.

   The Long Format
       If the -l option is given, the following information is displayed for each file: file mode, number of links, owner name, group name, number of bytes in the file, abbreviated month, day-of-month file was last modified,
       hour  file  last  modified, minute file last modified, and the pathname.  If the file or directory has extended attributes, the permissions field printed by the -l option is followed by a '@' character.  Otherwise, if
       the file or directory has extended security information (such as an access control list), the permissions field printed by the -l option is followed by a '+' character.  If the -% option is given, a '%' character fol‐
       lows the permissions field for dataless files and directories, possibly replacing the '@' or '+' character.

       If the modification time of the file is more than 6 months in the past or future, and the -D or -T are not specified, then the year of the last modification is displayed in place of the hour and minute fields.
