HELP Command
The HELP command displays help text for the interface commands that are supported in the
current operating mode.
Syntax
HELP [command-name]
command-name
is the name of an interface command that is supported in the current operating mode. If you
do not specify a command, NCI returns a list of all commands that are supported in the
current mode. If you specify SET, NCI returns a list of all SET commands that are supported
in the current mode. If you specify SHOW, NCI returns a list of all SHOW commands that
are supported in the current mode.
Considerations
You must enter the command on one line. The command does not require an SQL terminator.
Examples
• This HELP command lists all the commands that are supported in SQL mode:
SQL>help
• This HELP command lists all the SET commands that are supported in SQL mode:
SQL>help set
• This HELP command shows help text for SET IDLETIMEOUT:
SQL>help set idletimeout
• This HELP command lists all the SHOW commands that are supported in CS mode:
CS#help show
HISTORY Command
The HISTORY command displays recently executed commands, identifying each command by
a number that you can use to reexecute or edit the command.
Syntax
HISTORY [number]
number
is the number of commands to display. The default number is 10. The maximum number is
100.
Considerations
• You must enter the command on one line. The command does not require an SQL terminator.
• You can use the FC command to edit and re-execute a command in the history buffer, or
use the REPEAT command to re-execute a command without modifying it. See the “FC
Command” (page 96) or the “REPEAT Command” (page 115).
