help -- Command Print concise description of command help [-dc] [-ffile] [-ifile] [-r] [command]... help prints a concise description of the options available for each specified command. If command is omitted, help prints a simple description of itself, followed by information about the command given by $LASTERROR, which is the last command returning a nonzero exit status. help provides more information than the usage message printed by a command, but less than the detailed description given by the man command. The primary purpose of help is to refresh your memory if you have forgotten an option to command. help looks in /usr/lib/helpfile for system information and the file named in environmental variable $HELP for user-specific information. Information about a command begins with a line #command and ends with the next line beginning with `#' in /usr/lib/helpfile or $HELP. help recognizes the following options: -dc Use c as the delimiting character within the helpfile, instead of the default #. -ffile Read the help entries from file instead from the default, /usr/lib/helpfile. -ifile Read the helpfile's index from file instead of from the default, /usr/lib/helpindex. help uses the index to speed its retrieval of an entry, and does not work without it. -r Rebuild the index. If you modify a helpfile, you must rebuild its index, or help will no longer retrieve items correctly. Example The following shows how to rebuild the index for helpfile myhelp, using @ as the delimiting character: help -d@ -fmyhelp -imyindex -r Files /usr/lib/helpfile -- Additional system information /usr/lib/helpindex -- Index for helpfile $HELP -- User information $LASTERROR -- Default command help See Also apropos, commands, man, Using COHERENT
