Getting help using the Access CLISH
Access Appliance provides the following features to help you when you enter commands on the command line:
Auto-completion
The following keys both perform auto-completion for the current command line. If the command prefix is not unique, then the bell rings and a subsequent repeat of the key displays possible completions.
[enter] - Auto-completes, syntax-checks then executes a command. If there is a syntax error, then the offending part of the command line is highlighted and explained.
[space] - Auto-completes, or if the command is already resolved inserts a space.
Command-line help
Type a question mark at the command line to display context-sensitive Help. This is either a list of possible command completions with summaries, or the full syntax of the current command. A subsequent repeat of this key, when a command has been resolved, displays a detailed reference.
Keyboard shortcut keys
Move the cursor within the command line or delete text from the command line.
Command-line manual pages
Type man and the name of the command.
Error reporting
The ^ (caret) indicates a syntax error occurred in the preceding command statement. The location of a caret in the command statement indicates the location of the syntax error.
Escape sequences
Substitute the command line for a previous entry.

Note:
Most of the Access Appliance commands are executed asynchronously, so control may be returned to the command prompt before the operation is fully completed. For critical commands, you should verify the status of the command before proceeding. For example, after starting a NFS service, verify that the service is online.
