Command Line Interface
Command Line Interface
A restorer is administered through a command line interface. Use the SSH or TELNET (if enabled)
utilities to access the command prompt. The majority of this manual gives details for using the
commands to accomplish specific administration tasks. Each command also has a help page that
gives the complete command syntax. Help pages are available through the restorer
help
command
and in an appendix at the back of this manual.
•
To list restorer commands, enter a question mark (?) at the prompt.
•
To list the options for a particular command, enter the command with no options at the prompt.
•
To find a keyword used in a command option when you do not remember which command to
use, enter a question mark (?) or the
help
command followed by the keyword. For example,
the question mark followed by the keyword password displays all restorer command options
that include password . If the keyword matches a command, such as
net
, then the command
explanation appears.
•
To display a detailed explanation of a particular command, enter the
help
command followed
by a command name.
•
Use the up and down arrow keys to move through a displayed command. Use the
q
key to exit.
Enter a slash character (/) and a pattern to search for and highlight lines of particular interest.
•
The Tab key completes a command entry when that entry is unique. Tab completion works for
the first three levels of command components. For example, entering
syst
(tab)
sh
(tab)
st
(tab) displays the command
system show stats
.
•
Any restorer command that accepts a list, such as a list of IP addresses, accepts entries as
comma-separated, space-separated, or both.
•
Commands that display the use of disk space or the amount of data on disks compute amounts
using the following definitions:
1 KB = 2
10
bytes = 1024 bytes
1 MB = 2
20
bytes = 1,048,576 bytes
1 GB = 2
30
bytes = 1,073,741,824 bytes
1 TB = 2
40
bytes = 1,099,511,627,776 bytes
