Linux Shell Syntax
While this manual is primarily designed for using the E2000, 2500, and 5000 web interface, some special features show you how to configure the AlterPath Manager using the Serial Console Interface. The Serial Console configuration is discussed in the “Advanced Configuration” chapter of the AlterPath Manager Installation, Configuration, and User’s Guide. The typographical conventions used for showing the syntax for these commands are as follows.
Brackets
(
[]
)
Indicate that the parameter inside them is optional. The command will still be accepted if the parameter is not defined.
When the text inside the brackets starts with a dash (-) and/or indicates a list of characters, the parameter can be one of the letters listed within the brackets.
iptables [-ADC] chain 
rule-specification [options]
Indicate that the latest parameter can be repeated as many times as needed. Usually this is used to describe a list of subjects.
ls [OPTION]... [FILE]...
One of the parameters separated by this character should be used in the command.
netstat {--statistics|-s} 
[--tcp|-t] [--udp|-u]
[--raw|-w]
Text enclosed in greater than or less than symbols (or angle brackets) is variable text that is to be substituted in a specific command line.
add user <username>
Spacing and 
Separators
Lists will not normally have spaces between the items, but will have commas, hyphens, or semicolons as separators.
[<username>:<outlet_list>]

[;<username>:<outlet_list>...]
[<outlet_number>|<outlet_start>-
<outlet_end>][,<outlet_number>|

<outlet_start>
<outlet_end>]...
