You wanted the python code in bash so don't run before you can walk!
The code, (#11), CAN be improved, it also has no error detection nor reporting, it has no means of going over a persons wrongly inputted data and it WILL overwrite the file on every (re)run.
I left those those anomalies out for you to to learn by working them out.
And line 3 of your python code does NOT do what you expect: av1 = float(sum / 4)
As your example always shows integer values for q1 to q4 the let's see what happens...
As you can see, the float is a conversion of integer division.
Either that is a bug or q1 to q4 MUST be, for example, sum = 5.0+6.0+7.0+7.0 to arrive at 6.25...

Hi ,
this is the first time i use bc to calculate and i would have decimal result , i use the following :
toto=400;scale=1 echo $toto / 1000|bc
scale to adjust the numbers after the command would have in this case 0.4 as result and i wonder why i have always 0 as result.
Somebody can... (2 Replies)

About 4 years ago I wrote this tool inspired by Rob Urban's collect tool for DEC's Tru64 Unix. What makes this tool as different as collect was in its day is its ability to run at a low overhead and collect tons of stuff. I've expanded the general concept and even include data not available in... (0 Replies)

pmprintvalue
PMPRINTVALUE(3) Library Functions Manual PMPRINTVALUE(3)NAME
pmPrintValue - print a performance metric value
C SYNOPSIS
#include <stdio.h>
#include <pcp/pmapi.h>
void pmPrintValue(FILE *f, int valfmt, int type, const pmValue *val, int minwidth);
cc ... -lpcp
DESCRIPTION
The value of a single performance metric (as identified by val) is printed on the standard I/O stream identified by f.
The value of the performance metric is interpreted according to the format of val as defined by valfmt (from a pmValueSet within a pmResult
structure; see pmFetch(3)) and the generic description of the metrics type passed in via type.
The value for type is typically extracted from a pmDesc structure, following a call to pmLookupDesc(3) for a particular performance metric.
The output will be optionally padded to be at least minwidth characters wide.
pmPrintValue is most useful for displaying values of performance metrics from pmFetch(3) (which returns a set of valfmt and val pairs for
each requested metric), based upon the metrics type as returned from pmLookupDesc(3).
