Table 9-20 Primary Commands
Command Description
set
The
set command assigns a value to a variable. Syntax:
set <variable> <value>
where <variable> is a word, and <value> can be defined in one of the following
ways:
A quoted string
A word
A variable reference
A value generated via one of the string secondary commands (compare,
match, first, etc.)
A value generated via the expr secondary command
A value generated via the format secondary command
A value generated via the expr timestamp command
unset This command removes the definition of a variable within a script. Syntax:
unset <variable>
where
<variable> is a word.
scan
The
scan command is analogous to the C language scanf(). Syntax:
scan <variable> <format string> <value 1> <value 2> ... <value n>
where
<variable> a variable reference, and <format string> is a quoted
string. Each of the
<value x> elements will be a word.
sleep
The
sleep command suspends execution of the script (puts it to 'sleep') for the
specified number of seconds. Syntax:
sleep <value>
where
<value> can be a word, a quoted string or a variable reference.
exec
The
exec command executes a single CLI command. Currently only CLI 'show'
commands may be executed via exec. Syntax:
exec <CLI command>
send, send_user
The
send command sends output to a sub-process, The send_user
command sends output to the standard output. Both commands have the same
syntax:
send <string>
send_user <string>
where
<string> can be either a quoted string or a variable reference.
expect, expect_user,
expect_before,
expect_after,
expect_background
The
expect command waits for input and attempts to match it against one or
more patterns. If one of the patterns matches the input the corresponding
(optional) command is executed. All
expect commands have the same syntax:
expect {<string 1> {command 1} <string 2> {command 2} ... <string n> {command
n}}
where
<string x> will either be a quoted string, a variable reference or the
reserved word 'timeout.' The command x is optional, but the curly braces
('
{' and '}') are required. If present it must be a primary command.
return
The
return command terminates execution of the script and returns an optional
value to the calling environment. Syntax:
return <value>
where
<value> can be a word or a variable reference.
