Code:
syntax error in expression with " *2" : unexpected operator *
while executing :
"expr $bw *2"
invoked from within:
"$ns duplex-link $n1 $n3 [expr $bw *2] Mb [expr $rtt_1 /2-1 ]ms DropTail"

test
test(1) General Commands Manual test(1)Name
test - test conditional expression
Syntax
test expr
[ expr ]
Description
The command evaluates the expression expr. If the value of expr is true, the command returns a zero exit status; otherwise, it returns a
nonzero exit status. The command also returns a nonzero exit status if no arguments are specified.
Options
The following primitives are used to construct expr:
-r file Tests if the file exists and is readable.
-w file Tests if the file exists and is writable.
-f file Tests if the file exists and is not a directory.
-d file Tests if the file exists and is a directory.
-s file Tests if the file exists and has a size greater than zero.
-t [ fildes ] Tests if the open file, whose file descriptor number is fildes (1 by default), is associated with a terminal device.
-z s1 Tests if the length of string s1 is zero.
-n s1 Tests if the length of the string s1 is nonzero.
s1 = s2 Tests if the strings s1 and s2 are equal.
s1 != s2 Tests if the strings s1 and s2 are not equal.
s1 Tests if s1 is not the null string.
n1 -eq n2 Tests if number1 equals number2.
n1 -ge n2 Tests if number1 is greater than or equal to number2.
n1 -gt n2 Tests if number1 is greater than number2.
n1 -le n2 Tests if number1 is less than or equal to number2.
n1 -lt n2 Tests if number1 is less than number2.
n1 -ne n2 Tests if number1 is not equal to number2.
These primitives can be combined with the following operators:
!expr Negates evaluation of expression.
expr -a expr Tests logical and of two expressions.
expr -o expr Tests logical or of two expressions.
( expr... ) Groups expressions.
The -a operator takes precedence over the -o operator. Note that all the operators and flags are separate arguments to Note also that
parentheses are meaningful to the Shell and must be escaped.
