Hi All,
In the output of TOP command in my unix system, i monitored that some process has utilization more than 100% even some process has 4000% utilisation.
Please help me understand how it is possible to show more than 100% utilization.
Please see the screenshot below:... (2 Replies)

Am struggling, and wondering for the past more than one week that, how to calculate the total available and used memory/swap space.

ok, so I have a script im running on a linux box that uses "egrep" a lot. now, when i run this script, i check the TOP to see how much system resource it is using.
the "top" command gives the following output:

I'm not sure if this is even possible but I'm hoping to avoid generating a temporary file. What I'm trying to do is append a perl command to the start of a list created by grep, then send the entire thing to mail. This is mainly to ensure that something isn't wrong when the list is blank, but it... (2 Replies)

DC(1) General Commands Manual DC(1)
NAME
dc - desk calculator
SYNOPSIS
dc [ file ]
DESCRIPTION
Dc is an arbitrary precision desk calculator. Ordinarily it operates on decimal integers, but one may specify an input base, output base,
and a number of fractional digits to be maintained. The overall structure of dc is a stacking (reverse Polish) calculator. If an argument
is given, input is taken from that file until its end, then from the standard input. The following constructions are recognized:
number The value of the number is pushed on the stack. A number is an unbroken string of the digits 0-9A-F or 0-9a-f. A hexadecimal num-
ber beginning with a lower case letter must be preceded by a zero to distinguish it from the command associated with the letter. It
may be preceded by an underscore _ to input a negative number. Numbers may contain decimal points.
+ - / * % ^
Add subtract multiply divide remainder or exponentiate the top two values on the stack. The two entries are popped off the stack;
the result is pushed on the stack in their place. Any fractional part of an exponent is ignored.
sx
Sx Pop the top of the stack and store into a register named x, where x may be any character. Under operation S register x is treated
as a stack and the value is pushed on it.
lx
Lx Push the value in register x onto the stack. The register x is not altered. All registers start with zero value. Under operation
L register x is treated as a stack and its top value is popped onto the main stack.
d Duplicate the top value on the stack.
p Print the top value on the stack. The top value remains unchanged. P interprets the top of the stack as an text string, removes
it, and prints it.
f Print the values on the stack.
q
Q Exit the program. If executing a string, the recursion level is popped by two. Under operation Q the top value on the stack is
popped and the string execution level is popped by that value.
x Treat the top element of the stack as a character string and execute it as a string of dc commands.
X Replace the number on the top of the stack with its scale factor.
[ ... ]
Put the bracketed text string on the top of the stack.
<x
>x
=x Pop and compare the top two elements of the stack. Register x is executed if they obey the stated relation.
v Replace the top element on the stack by its square root. Any existing fractional part of the argument is taken into account, but
otherwise the scale factor is ignored.
! Interpret the rest of the line as a shell command.
c Clear the stack.
i The top value on the stack is popped and used as the number base for further input.
I Push the input base on the top of the stack.
o The top value on the stack is popped and used as the number base for further output. In bases larger than 10, each `digit' prints
as a group of decimal digits.
O Push the output base on the top of the stack.
k Pop the top of the stack, and use that value as a non-negative scale factor: the appropriate number of places are printed on output,
and maintained during multiplication, division, and exponentiation. The interaction of scale factor, input base, and output base
will be reasonable if all are changed together.
z Push the stack level onto the stack.
Z Replace the number on the top of the stack with its length.
? A line of input is taken from the input source (usually the terminal) and executed.
; : Used by bc for array operations.
The scale factor set by k determines how many digits are kept to the right of the decimal point. If s is the current scale factor, sa is
the scale of the first operand, sb is the scale of the second, and b is the (integer) second operand, results are truncated to the follow-
ing scales.
+,- max(sa,sb)
* min(sa+sb , max(s,sa,sb))
/ s
% so that dividend = divisor*quotient + remainder; remainder has sign of dividend
^ min(sax|b|, max(s,sa))
v max(s,sa)
EXAMPLES
[la1+dsa*pla10>y]sy
0sa1
lyx
Print the first ten values of n!

DIAGNOSTICS
x where x is an octal number: an internal error.
`Out of headers' for too many numbers being kept around.
`Nesting depth' for too many levels of nested execution.
BUGS
When the input base exceeds 16, there is no notation for digits greater than F.
Past its time.
