Chapter 2 Utilizing the Command Line Interface

Managing the XSR

 Command Abbreviation: You can abbreviate commands and keywords

to the minimum number of characters that define a unique

abbreviation. For example, you can abbreviate the

hostname

command to

hostn (but you cannot abbreviate to hos because other

commands also start with the letters

hos).

 Output Display: By default, output data are displayed one page at a

time if the data occupies more than one page. In this case, you can use

the spacebar to scroll down to the next page or press

ENTER to scroll

down one line at a time. The default page size is 132 characters wide,

23 rows high and they are configurable in a range from 0 to 512

characters using the

terminal command. Refer to the XSR CLI

Reference Guide for more information about the command.

 Command Recall: Non-help commands are stored in the command

history list buffer up to the last 32 commands. You can recall and edit

previous commands using shortcut keys. For example:

Ctrl+p/Ctrl+n will list the previous/next command respectively

and can be applied repeatedly. The up-arrow or down-arrow keys

provide the same feature if your terminal supports these keys.

 Tab Completion: Pressing the

TAB key or CTRL+I completes a command.

In case of an ambiguous match, the word is completed up to the

character which leads to ambiguity. For example,

hostname and

hostDos share the letters host, so tab completion completes the

“command”

ho to host.

 Carriage Return/Enter: Pressing the carriage return/

ENTER key signals

the end of a CLI command.

 Help Symbol: At any point you can enter the

? character to prompt for

a list of possible commands/parameters at a particular mode.

 Error: Proper error messages are displayed if the command could not

be issued due to syntax errors or invalid values made by the user.

Typing these characters will produce output as follows:

XSR#showFIioLLJl

% invalid input detected at '^' marker

XSR#
