NAME

help – print summary of commands and help strings

SYNOPSIS

help [ command ... ]

? [ command ... ]

DESCRIPTION

help prints a summary for each command in its argument list. With no arguments, help prints a list of all available Data ONTAP commands.

Full UNIX-style man pages for all filer commands and files are available in the /etc/man directory.

If the help facility doesn’t find a matching command, then all the command help strings are searched for a match.

VFILER CONSIDERATIONS

When run from a vfiler context, (e.g. via the vfiler run command), help lists and summarizes only those commands that can be executed in the context of the concerned vfiler.

EXAMPLES

In the following example, the command is found and displayed:

jayna> help version version – display Data ONTAP software version

In the next example below, the exact command match is not found and the matching command strings are displayed:

jayna> help display date – display or set date and time df – display free disk space hostname – set or display appliance name httpstat – display HTTP statistics nfsstat – display NFS statistics options – display or set options version – display Data ONTAP software version vol – display or change characteristics of volumes ypgroup – Display the NIS group cache entries environment – display environmental information

Here is a vfiler command match:

jayna> vfiler run vf1 help hostname ===== vf1 hostname – set or display appliance name

Vfilers can also do command string matches:

jayna> vfiler run vf1 help display ===== vf1 df – display free disk space hostname – set or display appliance name nfsstat – display NFS statistics options – display or set options ypgroup – Display the NIS group cache entries
