Swat Reference

The descriptions of the Swat commands will follow the following notational conventions:

command (alternative1|alternative2|...|alternativeN) () The parentheses enclose a set of alternatives separated by a vertical line. For example, the expression quit (cont|leave) means that either quit cont or quit leave can be used.
command [optional_argument] [] The brackets enclose optional arguments to the command. For example, the command alias [<word[<command>]>] could have zero, one, or two arguments because the <command> and <word> arguments are optional. Another example would be the command objwalk [<addr>] , which may take zero arguments if it is meant to use the default address, and one argument if the user gives it a particular address to look at.
command <type_of_argument> < > The angled brackets enclose the type of an argument rather than the actual string to be typed. For example, <addr> indicates an address expression and <argument> indicates some sort of argument, but (addr|type) means either the string addr or the string type .
* + An asterisk following any of the previous constructs indicates zero or more repetitions of the construct may be typed. An addition sign indicates one or more repetitions of the construct may be used. For example, unalias word * can be the unalias command by itself, or it can be followed by a list of words to be unaliased.
